crebras florum delapsorum. Drupe samaroidew, stipite 2-3 
lin. longo fulte, eum alis 14-2 poll. longe, 7-9 lin. late, 
apice obtusissime et sepe emarginate, basi rotundatz v. sub-

Two other species are mentioned as West African, T. ma- 
croptera and T. avicennoides, Guill. et Perr., both from Se- 
negambia. 
l. Conocarpus erecta, Jacq., 9. procumbens, DC. Prod. 8. p. 
16.— Sierra Leone, Vogel; on the Gambia, Don. 
According to Vogel, the woody stems of this species spread 
over.the ground for a considerable space, sending up a number of 
erect branches. 
The Anogeissus leiocarpus, Guill. ct Perr., is a native of Sene- 
gambia. 
l. Laguncularia racemosa, Gertn. fil. —DC. Prod. 3. p. 17.— 
Grand Bassa and Fernando Po, Vogel. Also in Senegal, and 
a common maritime plant in Tropical America. 
The Guiera Senegalensis, Lam., extends from Senegal to 
Cordofan. 
l. Poivrea grandiflora, Walp. Rep. 2. p. 64.—Combretum 
grandiflorum, Don, DC. Prod. 3. p. 21.—C. Afzelii, Don, 
Linn. Trans. 15. p. 437.— Sierra Leone, Don, Whitfield, 
Miss Turner; Munrovia, Vogel.— Fructus late 5-alatus. 
Embryo 5-angulatus, cotyledonibus crassiusculis convolutis, 
minus tamen quam in P. comosa. 
It appears to have been by mistake that Don placed his 
C. grandiflorum in his octandrous division of Combretum, for 
although a tetramerous flower may have been found by chance, 
by far the greater part, all indeed that 1 have seen, are penta- 
merous, and the seed has the cotyledons certainly convolute. 
€ thorns in this and other Poivree are formed of the lower 
Portion of the petiole, which remains attached to the stem, 
becoming hard and prickly after the upper portion has fallen off 
with the leaf. 2
