FLORA NIGRITIANA. 477 
~ Corolle tubus (tubus cum faucibus, N. ab E.) fere bipolli- 
caris, supra ovarium contractus, dein ventricosus, ad faucem 
ampliatus ; limbus subequalis. Anthere mutice, omnes sub- 
similes, loculis ciliatis inzequalibus, altero altius inserto bre- 
viore et magis divergente. Stylus apice divisus in lobos 
stigmatiferos 2 cuneato-dilatatos emarginatos. Flores ex 
Vogel erecti, corollis basi luteo-albidis, apice purpureis. 
l. Elytraria marginata, Beauv. ; N. ab E., in DC. Prod. 11. p. 
63.—Grand Bassa and Fernando Po, Vogel; St. Thomas, 
Don; Senegal to Oware, and scarcely to be distinguished 
from the common East Indian E. crenata, or the American 
E. virgata. 
The Nelsonia canescens, N. ab E., a native of Senegal and of 
à great portion of Africa, appears to grow also in Tropical 
America and Australia, Senegal has likewise supplied the five 
following Acanthacee, hitherto confined to that country : Phy- 
sichilus Senegalensis and P. barbatus, N. ab E., Polyechma 
micranthum and P. odorum, N. ab E., and Nomaphila levis, 
N. ab E. 
l. Brillaintaisia Lamium, Benth.—Leucoraphis Lamium, JV. 
ab E., in DC. Prod. 11. p. 97.—Fernando Po, Vogel, Ansell ; 
Sierra Leone, Don. 
2. Brillaintaisia Vogeliana, Benth.—Leucoraphis Vogeliana, N. 
ab E., in DC. Prod. 11. p. 97.—Fernando Po, Vogel; St. 
Thomas, Don. s 
There seems little doubt that these two plants belong to 
Beauvois’ genus. Brillaintaisia, as characterized in the Fl. Ow. 
et Ben., and accidentally overlooked by Nees. It is also very 
Probable that the species figured by Beauvois (B. Owariensis, 
Beauv. F/. Ow. et Ben. 2. p. 68. t. 100. f. 2.) is the Belanthera 
Belvisiana, N. ab E., notwithstanding the discrepancy of the 
` presence of the sterile stamens in Beauvois’ Brillaintaisia, and 
their absence in Nees’ Belanthera. Beauvois’ specimens are 
in general made up of mere’ fragments; and several cases are 
known where the details of the flowers in his figures are compiled 
from different plants. The fragments seen by Nees, left him 
also in some uncertainty as to their all belonging to one plant.
