found only in South Africa, where they are known as witte els or white alder. Their botanical name Platylophus trifoliatus means broad crest with trefoil leaves. The leaflets are 3-5 inches long.
kaffirboom (Erythrina caffra), a leguminous tree up to 60 feet in height, grows in woods not far from the sea in the eastern districts of South Africa and is often cultivated as an ornamental tree. The wood is soft and the trunks are hollowed out to make troughs and canoes. The leaves are clustered near the end of the branchlets. They are deciduous and appear later than the flowers, being fully developed just after the flowers are over.
The latter are up to 2 inches long and are massed in dense clusters. Their copious supply of nectar attracts sunbirds as well as bees.
There are about a hundred species of Erythrina in the warm regions of both hemispheres, five of which belong to South Africa. They are commonly known as coral trees on account of their bright red flowers, and the scientific name (derived from the Greek word eruthros, red) is also in reference to this character.
litvit, an epithet coined by the author for the arum-lily-frogs, his special pets at Ronde Vlei.
mabolel. - The Mabolel is the chief of the ‘many large holes in the Limpopo River (northern Transvaal), popularly known as hippo-holes, parts of the river where a dike of limestone or dolomite has dammed up the water so as to make a lake-like expanse. It is a huge pool (in good seasons) which in late afternoons with the sun glinting upon its wide waters seemed much larger than it really was. I judged it to be about half a mile long and 200 yards wide, overhung in parts by high trees which gave shelter to many different kinds of birds, making it not only an ornithologist's paradise but a place probably unrivalled in the Transvaal for the variety of natural interest it holds.’ (See ‘Bushveld Doctor’, pp. 143-159: ‘The Mabolel’ C.L.L.).
melat, probably an error for meloti, a name sometimes used for the camdeboo stinkwood, Celtis Kraussiana, which is found from Cape Town to Abyssinia, attaining a height of 80 feet in favourable situations.
sicklethorn (Dichrostachys glomerata), a shrub or small tree belonging to the Mimosa-group of the Leguminosae, and having sickle-shaped thorns on the leaves. The flowers are in spikes or ‘tassels,’ those in the lower part being pink or purplish and sterile and those in the upper part yellow and bearing pods in a close cluster. Dichrostachys, meaning two-coloured spike, is in reference to this characteristic, and glomerata probably alludes to the agglomerated pods.
twining lilies belong to the lily-family (Liliaceae) and to the small genus, Gloriosa, containing about six species, all with remarkably handsome flowers. They twine with the tendril-like tip of their leaves. Three species are found in South Africa, and very probably the species referred to here is the ‘superb’ one (G. superba), which has bright red and yellow flowers about 2 inches long.
usakos, a town near the borders of the Namib desert in South-West Africa, a country rich in minerals.
water-hawthorn or water-uintjie is a common aquatic plant whose floating leaves and fragrant flowers mantle whole vleis in the rainy season. During the dry season the plant dies down and the tuberous rootstock or ‘uintjie’ rests in the ground. Both the uintjies and the flowering-portion are eaten, and if properly prepared are very good and wholesome. It belongs to the naiad family (Naiadaceae) and is known botanically as Aponogeton distachyon, which might be paraphrased as meaning an inhabitant of calm water, with the inflorescence divided
