Mr. Johnson notes that the flowers are greenish and the plant produces “ pas'e 
rubber.” It closely resembles Euphorbia Teke, Schweinf. Probably Welwitsch, 
645, from the Island of St. Thomas, and 6458, from Princes Island, belong to 
this species, but the specimens consist of a few leaves only. See Hiern in Cat. Afr. 
Pl. Welw. i. 944. 
The Berlin Herbarium contains a specimen of Euphorbia grandifolia, Haw., 
cultivated at Berlin in 1858, from Sierra Leone, which is most probably correctly 
named, and although there are neither flowers nor fruit upon it, the cliaracter of the 
spines, leaf-scars, and form and apiculation of the leaves agree so exactly with those 
of Elaeophorbia drupifera as to leave no doubt that Euphorbia grandifolia, Haw., is 
i synonym of that species. The only other known plants with which it might be 
confused sre Euphorbia Teke, Schweinf., and EH. leonensis, N. E. Br., from Sierra 
Leone, but the spines, leaf-scars, and apiculation of the leaves are not quite the 
sume as in the former, and the latter differs in its subsessile cymes. Structurally 
also, when not jn fruit, the thick fleshy walls of the young ovary will always 
distingnish Eleophorbia from the Euphorbias, in which they are much thinner and 
less fleshy.

_ Apparent flower consisting of an entire cup-like 4-angled involucre, 
divided into 4 compartments by 4 thick cuneate-obovate partition-like 
glands, without a gland or glands on or around its margin and witiout 
inner lobes in the compartments; sometimes all the involucres of an 
inflorescence male, containing a group of 5-10 stamens (really male 
flowers asin Huphorbia, each with a small cup-like perianth just above the 
articulation) in each compartment, mingled with a similar number of 
bracteoles ; sometimes the terminal involucre of some of the branchlets 
bisexual, with a 4d-angled 4-celled pedicellate ovary (really a female 
ower, asin Huphorbia,with a small cup-like 4-angled perianth at the base 
of the Ovary) erect in its centre, surrounded by the 4 compartments 
full of stamens; ovule solitary in each cell, pendulous; styles 4, united 
at the base, stout, emarginate or shortly bifid at the apex. Fruit a 
4-celled capsule ; cells separating at maturity from the central persistent 
axis and opening along their inner face into 2 hard valves. Seeds 
ellipsoid or subglobose, without a caruncle ; testa crustaceous ; embryo 
Straight, with flat cotyledons, enclosed in copious albumen.—A small 
tree with milky juice. Leaves alternate, simple, exstipulate or the 
stipules very rudimentary. Panicles terminal, unisexual or bisexual. 
Species 1, endemic. 
In structure the involucre really consists of 8 bracts more or less fused together : 
“i outer series of 4, forming 4 pocket-like cavities at the corners containing the
