Machairophyllums flowering after fire

In an earlier post I referred to a fire that raged on the nearby Rooiberg about a year ago.
Approximately half a year after the fire we discovered a great number of flowering Machairophyllums in the burnt areas.
Although there are several populations on the Rooiberg, we had never found a flowering specimen before and we wondered why that was. Had we never been there in the right time of the year and of the day (the flowers open after dark) or did the plants, like so many others occurring in fynbos, need a fire to trigger flowering?
Last Sunday we decided to visit the mountain again and see if we could find out if the Machairophyllums in the not burned areas had flowered so profusely last year as well. This is easy to establish because the fruits stay on the plants for a long time. We saw a couple of hundred plants in perfect condition, but only very few with  (max. 2-3) fruits.  If you look at the accompanying pictures (taken last October), you will see how profusely the plants flower after a fire.
All in all It seems safe to say that  this species of Machairophyllum -and probably the others too- may not be totally dependent on fire to trigger flowering, but that it certainly makes an enormous difference.
When I say “this species of Machairophyllum “ you probably wonder exactly what species we are talking about here. Comparing all the information from literature, I come to the conclusion it is most probably M. albidum.  Apparently other people too have a problem deciding which is which in this genus: The Illustrated Handbook of Succulent Plants recognises 7 species but also says “The genus is under study and four or five species may only be distinguishable”.

This picture was taken at 6.32 PM, when there was still just enough light to use

Looking and seeing

“Our looking is perfected every day-but we see less and less. Never has it been more urgent to speak of SEEING. Onlookers we are, spectators…”subjects” we are, that look at “objects”. Quickly we stick labels on all that is, labels that stick once – and for all. By these labels we recognize everything but no longer SEE anything. We know the labels on all the bottles, but never taste the wine. “
Frederick Franck, The Zen of Seeing

“You learn to see by practice. It’s just like playing tennis, you get better the more you play. The more you look around at things, the more you see. The more you photograph, the more you realize what can be photographed and what can’t be photographed. You just have to keep doing it.”
Eliot Porter

When we want to take our photography to a higher level, we must learn to observe better. It is not about visiting exciting places and having wonderful subjects in front of us.
Even in the most ordinary places you may find something of interest. It has little to do with the things you see and everything with the way you see them. The more carefully you observe things, the better your pictures will become. You can only really learn how to do this when you are able to relax. As long as your mind is filled with worries and concerns, you are occupied with yourself and not with the things you want to see. Therefore, you must try to clear your mind. Unfortunately, this is easier said than done. A good start would be reading Jon Kabat-Zinn’s inspiring book  “Wherever You Go, There You Are”.
Once you know how to relax, you can go on to the second step: paying attention to something or somebody.
As Freeman Patterson says in one of his books: “The trick is to learn how to switch yourself off, so you can switch your subject matter on. You have to “let go”.”
In other words, you must develop an attitude of “relaxed attentiveness”. This sounds like a contradiction in terms, and certainly it is not is easily accomplished. Nevertheless, it is well worth trying to get there.
Mindfulness is another word to refer to this state, in which we are not going anywhere or looking for anything specifically, but are one with what is surrounding us. Once we are able to “switch ourselves off”, we allow the picture to find us, instead of us trying to find the picture.
Most of us seem to suffer from sensory overload nowadays and we cannot pay constant attention to all the stimuli that we are subjected to. It is however possible to tune in to specific ones if they are of sufficient interest to us.

I remember an afternoon during one of the first photo workshops that I attended in South Africa. We stopped somewhere in the mountains near Kamieskroon and within minutes everybody was happily shooting away at rocks, trees, flowers, insects and what not. Everybody except me, that is. I was still busy trying to wind down, to relax, to “get in the mood”. Suddenly I became aware of the enormous variety of subjects and of the many ways people were responding to them: some were on all fours , one or two were lying on their backs looking up into a tree, others were sitting on rocks or in trees looking down, etc, etc. So, if I was the only one not seeing anything worth photographing, it obviously had to do with me and not with a lack of suitable subject matter. As soon as I realised this, the “what should I photograph” spell was broken and I started taking pictures just as happily as all the others.

Often one is so focused on the point of interest in the picture frame, that all the rest is not seen consciously. Apparently, the brain filters out much of the “noise” around us.
Richard Zakia (Perception and Imaging, 1997) describes this as: “We only see a small fraction of what we look at, and more often than not we “level” what we look at rather than “sharpen” it.”
One of the strongest barriers to seeing is categorizing and labeling:
– “why should I take a picture of that, it is only a nasty weed”;
– “no good photographing this flower, it’s not fully open yet”;
– “I don’t know this plant’s name, so there’s no use spending time on it”, etc.
It is only when we can leave this stage behind us that we will really see and realise that even simple, daily things can be very interesting.
As Robert Adams (Beauty in Photography, 1996) puts it: “Bell peppers would seem to be about as limited as any subject matter could be, but in fact how unlimited they are when photographed by Weston.”
Another attitude problem is caused by the “been there, done that” syndrome: you look at something and think: “Well, yes, I have seen this many times before and I do have pictures of it, so why waste time looking at it again”. (Never mind that it is not exactly the same thing; it is a different time of day, another season etc.). It may even be very useful to return to the same subject several times, because this will force you to look at it in new and unusual ways.
We need to have something like the receptiveness of a child looking at a thing for the first time. We can only hope to regain this wonderful innocent vision by breaking away from rigid, conventional ways of seeing and thinking.
A good way to improve your seeing is to look regularly at possible subjects through a small opening cut in a piece of cardboard. The opening should be about 10 x 15 cm (with the same aspect ratio as your viewfinder.
Because drawing  sharpens the visual senses,  one of the best ways to learn how to see better would be to attend a couple of art classes or study a book on learning how to draw. This may sound strange at first, but when you give it a try, you will find out that it really works. You will not only start looking at things in a different way, but also see things you never saw before.

The above is a somewhat modified chapter of my ebook on plant photography. The rest of this post is devoted to a recent example of looking and seeing “out of the box”.

Last Wednesday our small local photo group had its monthly meeting.  All the members had to show a couple of pictures of kitchen implements. Hardly an interesting subject one may think, but its very mundaneness had forced us to look at things in a different way.
Some of the results were quite surprising. The following pictures were part of my contribution : there is no direct relationship with plant photography, but the pictures give you a good idea what can happen if you let go of pre-conceived notions of what things should look like.

Two interesting Euphorbias from the southern Great Karoo. Part 2: The start of a hybrid swarm?

Because this area harbours a variety of interesting succulents, we had high expectations of what we might come across. Nevertheless, the rest of the trip was rather boring. That is, till the moment George pointed out a big clump of what we both thought was Euphorbia stellispina, in a field next to the road. Finding that species in itself, would have been nice enough, but when we walked up to the plant, we discovered that it was much more special: about all the plant’s features were perfectly in between those of E. stellispina and E. heptagona.  The result was spectacular.

Two pictures of the purported hybrid

When we searched the immediate surroundings, we found plants of both these species, which strengthened the idea that our plant was a hybrid between the two.

To make the find even more exciting, after some looking around we came across another hybrid between the same parents.

More interesting than beautiful

Here the results of the mix are totally different and far less appealing. On the other hand it is exciting to witness what may be the beginning of a hybrid swarm and it would be interesting to follow the population’s behaviour over some time.

Two interesting Euphorbias from the southern Great Karoo, part 1: E. braunsii

Last month my  friend George Hatting and I decided to spend a Sunday looking for plants in the Prince Albert area. We had both been there before and discovered some interesting plants.  After a nice drive over the spectacular Swartberg Pass, we arrived in Prince Albert and took a gravel road road from there heading east. Shortly after leaving town, we stopped at a place that looked promising and found a couple of beautiful small Euphorbia’s.  They clearly were plants of E. braunsii, which is well known from the area.

This is how E. braunsii usually looks in the wild (well, normally without fruits, of course). Photo taken near Prince Albert on 10 Oct. 2012.

The peculiar thing was that they were in leaf, something I had never seen before and which is apparently a rare phenomenon. Digging into my literature I found no mention of the leaves, let alone a description or picture of them. The most likely explanation for this is that the leaves are short lived, as in the related (or maybe even identical) species E. rudis from Namaqualand and Namibia. Whatever is the case, I was quite chuffed to be there right on time to photograph the leaves, especially as they add an extra dimension to an already charming plant.

Next time we will look at a natural hybrid we discovered on this same trip.

Miniature succulents, part 2

Succulent organs filled with water are quite heavy. In miniature succulents most of the body weight is near the ground, so that there is little or no need to build and maintain a strong support system. Because they are so compact, they are also far less exposed to external influences than other plants.

Plants like this Conophytum praesectum from near Pofadder are small enough to benefit from shade cast by pebbles

The fact that a great part of the plant is near to the soil has another -and rather unexpected- advantage. In the areas where succulents grow, wind is usually present and is often hot and strong. The continuous replacement of air around the plants has a dehydrating effect, so that evaporation can be extreme. Apart from this, the wind transports sand and dust, causing sand abrasion, which may damage the plants (especially seedlings) and remove hairs or wax cover.
Because of surface roughness, wind speed is zero at ground level, and wind becomes stronger with increasing height above the ground. It follows that the lower the plant, the less likely it will be to suffer from wind damage.
A drawback of being small is that smaller leaves and stems have a larger surface-area-to-volume ratio than large ones. As a result, their transpiration is relatively higher and they are more prone to heat stress. The fact that dwarf succulents have more or less spherical leaves or stems, helps to alleviate the problem. With regard to minimising evaporation, a sphere is the ideal shape, as it combines the minimum surface area with the maximum internal volume. (The surface area of a flat leaf is about 40 times bigger than that of a perfect globe with the same contents).

In the rare Muiria hortenseae from the southern Little Karoo, the two leaves making up each body are fused almost completely, so that the flowers have to force their way out

In some cases, pairs of leaves have grown into one, so that each pair resembles a little globe. Densely packed leaves or stems can attain similar results.

In Crassula pyramidalis the leaves fit so densely together, that it first sight the plant looks like a stem succulent rather than a leaf succulent

Water loss from the surface of the plant can further be minimised by (the plant) hiding underground. In dry periods, the plants are often completely hidden in the soil, covered with the sand and dust blown over them. Only when the bodies fill out at the beginning of the rainy period do they appear above ground again.
Experiments have shown that in Lithops the rate of water loss is about a fifth lower in plants that are embedded in the soil than in those totally exposed.
In addition, the daily variation of temperature in the leaves is reduced. This is important during the hottest part of the day, when the parts of the plant that are furthest away from the soil surface, stay cooler than those nearer the ground.
Hiding underground also has its disadvantages. Because less surface area is available, photosynthesis is much reduced, so growth is slowed down.
The famous window plants have found a way to reduce this problem. These plants occur almost exclusively in the dry winter rainfall areas of southern Africa and are found in just a few families- most commonly the vygies (Aizoaceae, several genera). Other examples are Haworthia and Bulbine.

Haworthia truncata has a limited distribution area around Calitzdorp and Oudtshoorn. It is one of a number of Haworthias with windows

The classic example is Fenestraria rhopalophylla: The plants are practically stem less and have club-shaped leaves with a translucent area on top.
As only a small part of the leaves is exposed to light, photosynthesis would normally be seriously hampered. The window at the top however, combined with translucent water-storage cells deeper inside the leaf, makes it possible for light to penetrate into the leaf and reach the inside of its mantle. Here, (there) are cells that contain chlorophyll and make photosynthesis possible.
The plants grow in the mist zone on the coast of northern South Africa and southern Namibia where the leaves are drawn into the ground by thick contractile roots. Usually the plants grow in deep sand, but sometimes they are found in pockets above dolomite rocks. Although the plants are only a few centimeters across, the root system may cover up to 2 metres. The mat of fine roots just underneath the surface is able to absorb the condensation of the moisture brought in by the sea fog, which is the main source of water for these plants.
The leaves are usually flush with the sand so that they do not suffer from the strong winds that blow almost daily.

This F. rhopalophylla ssp. aurantiaca was photographed south of Port Nolloth, in close proximity to the sea

The so-called stone plants – among the smallest flowering plants in the world- have followed a slightly different route. They have very thick leaves, often with dark green dots in their leaf tops. These dots contain no pigment and may be either large single cells or a group of smaller ones. They lie just below the epidermis and serve as micro windows, which may take up to over 40% of the leaf surface. In winter, when the sunlight is weak, the non-pigmented zones help it to penetrate into the leaves.

A peculiar adaptation is shown by many members of the mesemb family (Aizoaceae), especially the dwarf ones, which are able to recycle water from old leaves to new ones.
This phenomenon was already discussed in an earlier post (Water recycling in succulents,  4th Dec. 2012), so please have a look there if you are interested.

In this article, I have tried to highlight some of the intriguing adaptations miniature succulents deploy in order to survive. Of course, these are only a few of the techniques and strategies they have in common with other succulents. But that is another story, for another day.


The original version of this article appeared in the most recent issue of Veld & Flora (March 2013). If you are interested in the immensely rich flora of South Africa, it is well worth visiting their website:


Since I wrote the article I acquired a new piece of software (Inspiration) which allows the user to make mind maps, concept maps, flow charts etc. in a very intuitive and easy way. I had tried out similar programs before, but never liked the results, nor the way they worked. To my mind, this program scores well on both points.

As I am currently working on a book on how succulents survive in the wild, I thought it might be helpful to use a diagram such as the one below, to make complicated processes and relations a bit clearer.
It would be great if  readers would have a critical look at this diagram and tell me if it works for them. Many thanks in advance!
