330 FLORA NIGRITIANA. 
The Entada scandens occurs among Heudelot's Senegambian 
plants, and a second species from the same country is described 
in the Flora Senegambize, under the name of E. Africana. 
1. Piptadenia ? Africana, Hook. fil. ; inermis, ramulis petiolis 
inflorescentiaque puberulis demum glabratis, glandulis nullis, 
pinnis 10-12 jugis, foliolis multijugis linearibus supra nitidis, 
floribus glabris, ovario subsessili glabro.—On the Niger, at 
Abóh, Vogel, Ansell. : 
Arbor excelsa. Folia iis P. communis simillima ; pinne 2-3- 
pollicares ; foliola 4 lin. longa, leviter falcata, obtusa v. acu- 
tiuscula, basi valde obliqua, glabra v. minute ciliata, supra 
nitidula, subtus subrufescentia. Spice bipollicares, in pani- 
culas axillares v. terminales disposite. Flores polygami secus 
rhachin sessiles, albidi, cum staminibus 2 lin. longi. Caly# 
brevis, cupuliformis, ore truncato leviter undulato. Petala 
lineari-lanceolata, acuta. Stamina 10, antheris apice glandu- 
liferis. Ovarium subsessile, glabrum, pluriovulatum. 
These specimens, in flower only, can only be distinguished 
from the Brazilian P. communis by the absence of all glands on 
the petiole, and by the nearly sessile ovary ; characters which 
may possibly prove not to be absolutely constant in the 
genus. 
Four other Mimosee, with glanduliferous anthers, are natives 
of West Tropical Africa, viz.: Tetrapleura Thonningii, Benth.,* 
from Guinea; Prosopis ? oblonga, Benth., from Senegambia, to 
which may perhaps be referred the Coulteria Africana, Guill. et 
Perr. ; Dichrostachys nutans, Benth., from Senegambia, ex- 
tending through a considerable portion of Tropical Africa; and 
Neptunia oleracea, Lour., a common aquatic plant, both in the 
New and the Old World.

* In the Spicilegia Gorgonea, above, p. 131, Parlatore has given the 
name of Tetrapleura to an Umbelliferous genus, not being then aware o 
my having previously published the Mimoseous plant referred to in the 
text under the same name. The volume of Hooker's Journal of Botany; 
in which it is described, though published in 1842, did not reach Florence 
till 1847,—(G. B.)
