Not illustrated. 1906 edition. Excerpt: ...D). This common tree is probably only too well-known to most of us as certainly one of the most provoking of all the thorned trees in the country. The leaves are smooth, dark green, and more or less spade-shaped. The two stipular thorns which issue from the base of each leaf point in diflerent directions, one being hooked and curving backwards and the other being straight. It is said to grow to a height of 60 feet with a diameter of 2% feet; this size is, however, seldom attained. The fruit is a berry about the size of a large pea and is edible. It may be remarked that in some varieties the thorns appear to be practically suppressed, though this is probably only a temporary phenomenon. The tree is irregularly deciduous, some trees retaining their leaves while in ot-hers they have fallen; this, as Miss Gibb remarks, is simply an example of the adaption of plants to their particular environment. According to Mr. Sim the root is gelatinous, and in the Colony a decoction is used internally for certain scrophulous diseases and swollen neck glands. We have one or more other species in the country, but they are mainly low-growing fruticaceous shrublets, common in many places and bearing edible berries and abominable thorns (e.g. Z. Zeyheriana, etc.). The tree has a rough dark-coloured bark and very hard yellow wood, which is used for the handles of farm implements, yokes, etc. This is a small tree or bush, flowering and fruiting in October. It should be a possible source of hemp fibre, like its congeners in India. These are small trees and shrubs, but mainly the latter and not growing to much more than 10 feet in height. It flowers in October. The fruit is a drupe with an astringent flavour but sweet, and is much appreciated both by natives more
