dahl's C. pubescens, from South-west Australia. Brown him- 
self, however, observes that the Congo species can scarcely be 
distinguished either from the West Indian one or from his own 
C. pubescens. The stems of the West African plant are some- 
times thickly pubescent, sometimes nearly smooth, the flowers 
usually distinct and rather distant, occupying the upper half of 
the peduncle, and agreeing in structure with those of the Bra- 
zilian plant. 
No species of true Laurinee has been hitherto recorded from 
West Tropical Africa; nor have I seen any specimen from 
thenee, excepting one in leaf only of the Cinnamon (Cinnamo- 
mum Zeylanicum), in Don's collection, from St. Thomas. But 
this is evidently a eultivated plant, as is also a specimen, in 
leaf only, in the same collection, of Myristica sebifera, Sw., 
no species being known from this region of the Order of 
Myristicee.

This may be the Guinea plant referred to E. Chamesyce by 
Schumacher and Thonning, and is certainly very near that 
species. The leaves are, however, more oblique, the flowers 
very much smaller, and usually two or more together in each 
axila, although often, in reality, solitary in the axille of very 
much reduced floral leaves, on axillary flowering branches 
much shorter than the subtending leaf. The capsule is much 
smaller than in E. Chamesyce, always ciliate on the dorsal ribs, 
and generally without hairs on the sides of the carpels. The 
African specimens precisely correspond with the South American 
ones. 
The E. scordifolia, Jacq., to which Planchon refers E. tomen- 
tosa, Poit., extends from Senegal to Nubia and Arabia.
