A couple of months ago my wife and I were travelling to our farm near Matjiesfontein when we decided to have a short coffee break. As usual, I utilized this opportunity to quickly scan the area. Not far from the road I came across a plant of Cotyledon orbiculata (the beautiful form that used to be called undulata).
This picture shows my first attempt of photographing the plant.
It is not a bad photo, but neither does it convey the feeling I got when looking at the subject.
After cropping the picture this is what I got. Much better I thought, but too realistic.
Cropping in a slightly different way, combined with darkening the picture and enhancing the colours, resulted in this.
It seemed to me I was on the right track, but now the left side of the photo was too busy and distracting.
I had also made another picture, almost identical to the first one, but taken from a slightly different angle. When I closely compared the two, it became clear that the second one would be the best starting point for the picture I wanted.
I first treated the picture the same way as in number 3 and the lowered the contrast.
This is the end result, realistic enough to be of botanical value, but at the same time visually stimulating.
The editor of “Veld & Flora” ( http://www.botanicalsociety.org.za/) invited me to write an article on succulents for the magazine. It is now ready and will be published in the March issue.
The article is called “Miniature succulents – masters of survival” and highlights some of the intriguing adaptations miniature succulents deploy in order to survive. The following snippet will give you some idea of what to expect.
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.
As the soil dries out towards the end of the growing period, the older leaves are gradually sacrificed and their water content is translocated to and stored in the younger ones. In this way, all available water reserves are concentrated in the last pair of leaves.
In the end, the dry remnants of the old leaves form a papery sheath acting as a protective layer of insulation for the new ones. When the next rainy period starts, the new pair reaches its final size and bursts through the old skin, ready for action.
It has been found that this adaptation enables plants to survive for about a year without any moisture supply from outside.
These three pictures of Antimima pygmaea were taken near Matjiesfontein in winter (mid August), spring (early October) and summer (end of January) respectively. At first, it would be hard to believe that it is all one species.
A short while ago I stumbled upon a website that turned out to be very interesting.
Here is the link: http://www.ispot.org.za,
and here is what they themselves say about the site:
“So what’s it all about?
iSpot is a website aimed at helping anyone identify anything in nature.
Once you’ve registered, you can add an observation to the website and suggest an identification yourself or see if anyone else can identify it for you.
You can also help others by adding an identification to an existing observation, which you may like to do as your knowledge grows. Your reputation on the site will grow as people agree with your identifications.
You may also like to visit our forums which offer lively debate around observations and other more general topics.”
The first time a saw a plant of Pelargonium tetragonum in the wild was in the vicinity of Calitzdorp. Later on I found out that the species was rather plentiful in the area, both north and south of the village.
The plants cannot be confused with any other species, but what surprised me was the colour of the flowers.
All the many plants I had seen in cultivation had pale pink flowers with deep red stripes on the upper two petals. All the plant I saw in the wild, not just around Calitzdorp but also elsewhere, had cream flowers (with the same red stripes as in the cultivated ones).
The more I thought about this phenomenon, the more I got the idea that the plants in cultivation originated from one or a few ancestors with an aberrant flower colour.
Last months I was in the Eastern Cape looking for plants with my wife and two Belgian plant friends. While trying to find my way into a dense thicket near Uitenhage, I suddenly came across several plants of this species with beautiful pink flowers.
So clearly the flower colour has to do with the area where the plants grow. According to J.J.A. van der Walt in “Pelargoniums of Southern Africa” (1977) the species occurs ” in a strip parallel with the coast from the Worcester-Caledon districts eastwards to Grahamstown. It has also been collected further inland near Graaff Reinet and Bedford”.
In their natural habitat the plants flower from September to December.
A few weeks ago my friend George Hattingh, who is about as mad about succulents as I am, told me that he had seen some beautiful succulents in flower which he could not identify. They were growing on top of the Rooiberg, a little mountain range just South of Calitzdorp which you have to cross on the way to Vanwyksdorp. As the road meanders its way up, it takes you through different vegetation zones. At the lower slopes a lot of succulents are found, whereas the plateau with its moister and colder climate is covered in arid fynbos. In winter and early spring the fynbos is at its best, with many different plant in flower. This type of vegetation harbours only few succulents, but some of the ones that do grow there are rather interesting. One of the plants George had found is probably an Antimima, but these I often find difficult to name. All suggestions are welcome.
The other species was clearly a Drosanthemum, but which one? After going through the literature, the only species of which the description fitted was D. striatum. According to the “Red List of South African Plants” (2009) this is a vulnerable species with only 10 locations remaining after much its habitat has been transformed for wheat and vineyard cultivation. The distribution range is given as: Malmesbury and Worcester to Swellendam and Bredasdorp. This is well outside the Calitzdorp area (even the nearest of these places is at least a 100 kms away). This new find means that the species has a rather wider distribution than assumed; hopefully it also means that it is less vulnerable than thought.
The peculiar thing is that we never found the plants before. The most likely explanation is that -like many other fynbos plants- they only flowers after fire. Or maybe we just missed them because they were too well hidden by all the vegetation that is normally present. Even without flowers they would have been much more visible without all kinds of other plants hiding them. At this moment (about seven months after a big fire on the mountain) large patches are still almost bare, so anything colourful stands out.
Whatever the reason, it just shows that interesting botanical discoveries can still be found in this part of the world.
This is the beginning of a blog that is focused on two topics. Firstly on anything that has to do with succulent plants, especially those growing in South Africa, because that is were I live.
Secondly on photographing plants, succulent or not, cultivated or in the wild.
These two things have kept me busy for many years and I have written and lectured on them for almost as long. I have the privilege of living in an area where interesting succulents grow almost on my doorstep and as I am retired I have lots of time to study and photograph them
