8permacoce natale7isis, Hochst. (Eubiaceae), a slender herb with pairs o£ 
lanceolate glabrous leaves and small dense axillary inflorescences. 
Heliclirysum longifolium, DC, and a variety of the same (Compositae),. 
densely clothed with long, slender, woolly hairs, and with narrow 
erect leaves closely appressed to the stem. 
Helichrysum sp., with most of the leaves radical, and densely woolly 
♦ except on the upper surface of the leaves. 
Senecio latifolius, DC. var. (Compositae), a tall herb with large glabrous. 
leaves and a large corymb. 
Stachys sp. (Labiatae), a low herb with long, erect, greyish, scattered hairs. 
Gommeliyia Krebsiana, Kunth. var., with a fairly large leaf-surface, 
covered with a finely silky appressed down. 
Lobelia Erinns, Linn. (Campanulaceae), a low, slender, mesophytic^ 
glabrous herb. 
Hibiscus Trionum, Linn. (Malvaceae), a small plant with abundant long 
hairs on stem and petiole. 
Geranium ornitho]) odium, E. & Z. (?), a low herb with large leaves with 
a dense appressed down on the lower side, and to a less extent on the 
upper, and with shaggy petioles. 
Hedyotis natalensis, Hochst. (Eubiaceae), a mesophytic herb with a few 
hairs on both leaf-surfaces.

It will be seen from the above examples, most of which are common 
plants in the savannah, that it is impossible at present to relate their 
external features to their environment. They are so diverse in aspect that 
it appears as though the basis of agreement that enables them to co-exist in 
such a uniform environment must be deep seated, and does not wholly 
depend on surface characters of hairiness and so forth. 
A quadrant with an edge of two metres was selected for closer examina- 
tion. The ground on which it was situated had recently been burnt over^ 
as seen from the blackened stumps of some of the grasses. The dominant 
plant was Eriantlius Sorghum, of whose tall tufts fifty-two were present,, 
each tuft having about ten shoots. Beneath these was a lower growth of 
about seventy-five tufts of JDigitaria sanguinalis, var, ciliaris ; and one large 
patch, about 20 cm. in diameter, of Panicum aeguinerve, this probably 
having all arisen from one seed. Of the B,hus sp. there were six branching 
shoots from the base of a single plant, all growing from one long horizontal 
rhizome running about two inches below the surface of the ground. Ten 
plants of Senecio latifolius, each about 50 cm. high, were present ; three 
plants of S]jermacoce natalensis ; six plants of the Stacliys sp. each with 
4-6 straggling branches and a slightly tuberous root; about six plants of;
