Augea capensis

When one sees a great many of these plants together, this usually means that the local vegetation has been heavily disturbed (the plants are rarely eaten by stock or game because the juice in the leaves is very salty). They can absorb a great amount of water after rain, not only in the leaves but also in the roots.

The plants usually live for only a few years or, in more official terms, they are annuals or short-lived perennials, up to 50 cm tall with leaves 3-4 cm long and about 1 cm thick.
The flowers appear in spring (August-October) and produce large fruits with woolly seeds.
This species (the only one in the genus) is widespread on dry sandy or loamy flats from southern Namibia and Bushmanland to the Little Karoo.

Pelargonium echinatum (part 1 of 2)

The specific name echinatus means prickly or armed with spines or prickles and is derived from the word echinus (hedgehog).
When you look at the recurved thorny stipules on the stems, it is easy to see where the name comes from.

The plants may be up to 60 cm tall, but are usually much smaller; they have few to many branches, with leaves 2-3 cm long and 3-4 cm broad on relatively long stalks.
The flowers are about 3 cm in diameter and appear from July to November in groups of 3-8. They vary in colour from white and pink to brilliant purple, with darker blotches.
This beautiful and interesting species occurs from the Richtersveld to Clanwilliam,
usually on dry granite or sandstone slopes and protected by bushes or overhanging rocks.

In search of the ideal tripod for plant photography

Most cameras nowadays are small and light, so the need for support is less than it used to be. But still: think of people working with heavy lenses for sport or wildlife photography. What of astrophotography, panoramas, time lapse. And what about the plant photographer who wants to make more than just snapshots of his subjects.
Using a tripod has a few drawbacks:
– it adds extra weight and volume to what you already have to carry.
– setting it up takes time and slows you down. Actually this may be more of an advantage than a drawback. It makes you more aware of the subject and its surroundings. Also, because you have invested time and effort, you will be less inclined to rush on after taking your picture; you will probably look again at your subject and start asking questions like: what if I go a bit nearer; is there a way to get rid of that disturbing item in the background; would a different angle be better etc. etc.
The main advantage of a tripod is that it supplies stability (after all, that’s its raison d’ être) and allows you to take pictures that would otherwise be impossible or at least much more difficult. In my case for instance, I often have to kneel down because I want to photograph a plant (or a part of it) at ground level. And let me tell you, in such a situation having the camera on a tripod makes life a lot more pleasant.
The use of a tripod also allows you to easily play around with different lenses, magnifications, apertures, shutter speeds and so on.

Over the years I have acquired several tripods, depending on the purpose I wanted them for and on what was available. Most of them are now gathering dust in a cupboard, either because they were not as great as they once seemed, because I don’t need them for the type of work I do now, or because something more suitable has appeared on the scene.
When I look at the tripods I have used most for plant photography, two of them stand out and both are rather different from the usual type of tripod.
The most versatile of the two is the Benbo (not Benro!) Trekker, which was my favourite up to a few months ago. Unfortunately, its versatility also means that it is often rather awkward to use.
The second one is the GorillaPod Focus, which is easy to work with, but has a limited scope.
Between them, these two gave me about all the options I needed, but this came at a price: having to drag along a heavy camera bag as well as two tripods in the field is no fun. So, in many instances I took only one with me and then regretted not having the other one available as well.
Slowly it dawned upon me that maybe I should start looking for a new tripod that combined as many advantages of these two as possible, but without the disadvantages.

Finding this ideal tripod was made complicated by conflicting wishes:
– the tripod had to be small when not in use, but big enough when extended;
– I wanted it to be as light as possible, but at the same time sturdy enough to secure a DSLR with a heavy macro lens;
– it had to be versatile as well as easy to work with;
– the tripod should allow me to make pictures at low level without the need for physiotherapy afterwards (ever seen pictures of someone trying to take photos with a camera hanging down from the tripod’s inverted centre column)?

For quite a while, trying to find a tripod combining all these wishes looked like expecting the impossible. But then suddenly one came along, from an unexpected corner of the tripod universe. Until not long ago I would have shuddered at the idea of buying a piece of photographic equipment both designed and manufactured in China. In this case, not only did it tick all the boxes of my wish list, but nearly all the reviews I saw were very positive, both on the count of practical use and of durability. The more I looked into it, the more attractive it became and so now I am the happy owner of a Sirui T-025X.
The following characteristics clinched the deal for me:
– the legs are made of carbon fibre for a light and strong construction.
– at its shortest, the tripod itself is only 32 cm; the ball head adds 6.5 cm.
– because the legs have three different angle settings and the centre column is removable, you can shoot from as low as 18 cm. This works especially well if your camera has a tilt and swivel LCD screen. If you want to go even lower, you will have to resort to a beanbag or one or two pieces of foam rubber to support the camera.
– with a maximum height of 139 cm the tripod can also be used for shooting tall plants and scenery -The tripod comes with a hook so that you can hang your camerabag or something else from it to lower the centre of gravity.
– the tripod/ball head combination weighs only 800g and can carry up to 6kg, enough for a DSLR with a 105 mm macro lens.

After working extensively with the Sirui during my recent trip to Madagascar, I can say it did everything it was supposed to do, with very little fuss. In other words, it proved its value not just for plant photography, but also as a general travel tripod.
As everyone’s requirements and methods are different, obviously this tripod may not be for you, but if you are not happy with the one you use now, it is probably worth having a look at it.

Uncarina stellulifera

Uncarina is a genus of 12 species occurring in northern, western and southwestern Madagascar.
U. stellulilifera is common between limestone rocks in the Tulear region, between Morondava in the north and Lake Tsimanampetsotse in the south.
It is a small tree up to 3.5 m tall, with a thickened base and leaves 4-12 cm long and 3-10 cm wide. The beautiful flowers are 5-6 cm long.
The fruits are most peculiar with their very long barbed spines, which attach them to passing animals as an aid in dispersal. We were told that the local people use the fruits to catch mice.

Euphorbia hamata (incl. peltigera)

Hamata means hooked, an apt specific name for this species with its recurved tubercles.

The plants often form dense, much-branched clumps up to about 50 cm tall and 60 cm or more in diameter with a thickened main stem.
The flowers (cyathia really) are surrounded by green or yellowish to red bracts and appear from April to September.
One can find this species from Luederitz in southern Namibia to SE of Worcester in the Western Cape, usually on stony slopes.

Brianhuntleya intrusa

On seeing this species for the first time, one would be excused for mistaking it for an Antegibbaeum. It was first described as a Ruschia, but in 2003 a new genus was established just for this one species. Since then, two more species have been added. If you are interested in the whole complicated story, you should read A Gordion knot in Ruschioideae by H. Hartmann and I. Niesler in Bradleya 30/2012, p. 33-60.

The plants form dense mats 7-10 cm high with persistent leaves 5 to 6 cm long and 0.7-0.8 cm wide.
They flower in June-August; the flowers have long stalks (to 5 cm long), are to 3.5 cm in diameter and open for only a few hours in the afternoon. After pollination they turn into
tumble fruits.
Although the species grows only in the Robertson, Swellendam and Worcester districts of the western Cape, it is locally abundant there, usually in full sun on gentle shale slopes, at an altitude of 200-250 m. In this area most of the rainfall occurs in winter.

Senecio crassissimus

Because of the peculiar orientation of its leaves, this species is often called Vertical Leaf Senecio or propeller plant.
The plants have creeping to erect stems, to 80 cm tall and much-branched.
The vertically flattened leaves* are variable in shape, size and colour, to 10 cm long, 3 cm wide and 3-5 mm thick.
Inflorescences are to a meter tall.

The species is widespread in central and southern Madagascar, where it grows on denuded granite rocks, often together with members of the Euphorbia milii groep, such as E. horombensis and E. fianarantsoae and Pachypodium species (first picture shows P. horombense in foreground).

* This vertical compression of the leaves is usually regarded as an adaptation which reduces the amount of light that reaches the leaf surface, resulting in lower daily water loss than in leaves in other orientations.

Euphorbia primulifolia (var. primulifolia)

At the end of our latest trip to Madagascar, we stayed in Antsirabe, south of the capital Antananarivo. The area is well known for its succulents and I decided to spend an afternoon in the mountains surrounding the town. For several kilometers the road leading out of town ran through the middle of a wide valley, and what I could see of the mountain slopes did not look promising at all. At a certain moment we decide to take a little side road that seemed to take us out of the valley. This was indeed the case, but even the hillsides appeared to be cultivated.
When the driver asked talked some local people if there were any bare rocks nearby, he got a positive reply, but in spite of their directions no rocks came into view. At a loss what to do now, I decided to just stop at an uncultivated spot and look around.
Picture #1 shows the first plant that I noticed there. Without flowers it could be about anything, but next to it was a group of flowering plants (#2) and immediately the penny dropped.

With a large tuber 10-15 cm long and to 7 cm thick, Euph. primulifolia is a true geophyte. It has a very short stem, hidden in the ground, with a radial rosette of 4-12 leaves. In the dry season the plants are leafless and hidden in the grass; in other words, they are only visible in the rainy season. This growth form allows the plants to survive the yearly grass burning.
The leaves are flat or undulate, 8-11 cm long and 3-4 cm wide.
Usually the plants flower before the leaves appear, but as the pictures show, this was not the case here. The cyatophylls* vary from white or greenish to pink and violet.

This variable species is widespread in the central highlands at about 1400-1500 m in a variety of substrates.

* cyatophylls are the bracts that surround the inflorescence proper in many members of the Euphorbiaceae.

Kalanchoe linearifolia

Because this species is often more or less climbing in surrounding shrubs, it is difficult to spot when not in flower. The name refers to the very narrow leaves, which are up to 13 cm long, but not more than 1 cm wide.
The plants become up to 1.5 m tall and produce brilliant red flowers with a tube just over 1 cm long.

One can find the plants in a wide strip roughly following the coast of southern Madagascar from Fort Dauphin to Tulear, where they mainly grow in xerophytic bush on limestone rocks.

The photos were taken at Madagascar’s southernmost tip (Cap Ste Marie) on 2 Nov. 2016.
