Here's a type of aloe:

Quite a number of species of these spiny succulents can be found in southern Africa, and they range in size from about 30 cm tall such as the one I sketched, to sizable trees.
And then a quick sketch of a smallish Strelitzia:

Larger specimens are also common in the garden, and I took a close-up of one of their quite exotic-looking flowers:

Here's a type of Euphorbia:

The genus Euphorbia is quite large and the plants range from small herbs, to medium-sized trees such as the above one, to quite large trees. Just about all of them contain a milky latex, and in the case of these tree-sized ones, colloquially known as candelabra trees, the latex is a quite potent skin irritant that will make you break out in red welts. It has traditionally been used as a fish poison (poured into rivers or dams, it stupefies the fish so that they can be caught by hand) and also to kill maggots in open wounds on livestock. So these trees are not to be trifled with. When I was in primary school I once went on a school camping trip, and when we arrived at the camp, a bunch of kids from another school were just leaving. One of them looked like he had had an altercation with a blowtorch. Well, it was one of those junior paramilitary type camps; in those days they were more or less compulsory. I have no idea what the situation is nowadays. Anyway, one of the things you were supposed to do was to learn how to camouflage yourself. The standard way is to simply smear your face with mud. But this poor city kid got creative and made a paste of soil and Euphorbia latex for his facial camouflage assignment. Some things you only do once.
Last but not least, the dry fruit of a wild teak (Pterocarpus angolensis), found in the warmer areas of the country. This time of year the trees are quite attractive, covered with these large pods. On my screen it shows up about actual size; two match boxes would just about cover it.

The wood of the wild teak is of high quality and can be used to make furniture.
That's it. Next time I'll take new batteries for the camera, and a bigger sketchbook.
