Fes, 1906,] | FLORA OF PORTUGUESE EAST AFRICA. 175 
ANACARDIACEA.—Rhus: about thirty species are described 
from Cape Colony to Natal. I can only locate the following 
species in the coast flora: Rhus insignis, R. gluucescens, R. 
villosa, and R. longifolia—small trees, rather resinous. MJan- 
gifera indica: this is the only species I have seen in 8. Africa, 
introduced from India, but the mango (fruit) is poor, the 
trees are not cultivated and not of a good variety. We are 
now introducing good varieties from India and elsewhere. 
Anacardium occidentale (Cashew nut), introduced, but has 
now become naturalised. The largest trees I have ever 
seen are on the island of Chiloane. They are a great source 
of food for the Cafirs—the fruit, nuts; and a spirit from the 
fermented fruit is made, very intoxicating, which both Cafir 
men and women relish until they are dead drunk.  Selero- 
carya caffra, a glabrous tree; the oily cotyledons are edible. 
The drupe is peculiar in its formation. 
LEGUMINOSH.—This is an Order of considerable interest 
and magnitude. As in Asia, so in Africa it includes many 
valuable food-products and highly commercial timber trees. 
Some portions of our African silva must give way to this 
Order entirely. Nearly a hundred genera attached under this 
name, and many handsome plants. Cvotalaria, over a hundred 
species in Africa. Open land, cultivated and abandoned 
fields they are to be found. On the coast I have observed 
C. capensis, C. globifera, C. macrocarpa, C. natalitia, C. 
striata, and C. lanceolata. Argyrolobium uniflorum, A. ascen- 
dens, and A. racemosum, all frequently found. Medicago 
lupulina, M. denticulata, and M. laciniata are not uncommon. 
Melilotus parviflora, a common weed. Trifolium africanum, 
abundant. Lotus arabicus, not uncommon. Psoralea pinnata 
and P. obtusifolia, both to be found in open ground. ndigo- 
jera: being so many, it is confusing keeping them all in 
recollection. Many of them are very attractive plants, more or 
less found in open ground. Indigofera Dregeanu, I. endeca- 
phylla, I. hirsuta, I vestita, I. micrantha, I. velutina, and J. 
polycarpa, all to be collected within the coast-line and islands. 
Tephrosia canescens, T. discolor, T. macropoda, and 7’. longipes are 
all found. Mundulea suberosa, an old favourite, very showy 
plant, and found at certain places on the coast. This plant has 
a remarkably wide range. The last place I collected it at 
was in the north of Ceylon, in the dry zone, among rocks at
