FLORA NIGRITIANA. 455 
all from Angola, viz.: G. pulchellus, Dene., G. lineolatus, Dcne., 
G. cristatus, Dene., and G. chironioides, Dene. 
1. Tylophora sylvatica, Dene. in DC. Prod. 8. p. 610.—Cape 
Palmas and Fernando Po, Vogel ; Senegambia. 
Dr. Planchon considers the Fernando Po specimens as be- 
longing to a distinct species, with larger and deeper coloured 
scales to the staminal corona; but on a careful comparison with 
the Senegalese specimen in the Hookerian Herbarium, the only 
differences I can perceive appear to me to arise from the Fer- 
nando Po specimens being in full flower, whilst on Heudelot’s 
there are only young buds. 
l. Marsdenia Leonensis, Benth.; volubilis, subglabra, foliis 
cordatis oblongis v. ovato-lanceolatis acuminatis, cymis petiolo 
brevioribus laxiusculis, corollz laciniis tubo intus dense piloso 
brevioribus, coronz stamine: foliolis bilobis, lobo interiore 
anthere alte adnato lineari gynostegium subzquante, ex- 
teriore brevi ovato obtuso.— Sierra Leone, Vogel. 
Folia subtripollicaria, longiuscule petiolata, supra petiolum mi- 
nute glandulifera, subtus ad costas ramuli inflorescentiaque mi- 
nute puberula, planta czeterum glabra. Cyme bifidz, breviter 
peduneulatze, Calyx semilinea brevior. Corolle tubus sub- 
globoso-campanulatus, lineam longus, presertim ad faucem 
intus dense barbatus. 
In the structure of the flower, this species appears to come 
near to M. Calesiana, Dene, which is unknown to me. 
2. Marsdenia glabriflora, Benth. ; volubilis? glabra, foliis cor- 
dato-oblongis v. ovato-lanceolatis acuminatis, eymis multi- 
floris in paniculam terminalem dispositis, corollæ undique 
glabræ laciniis ovatis tubo longioribus, coronæ stammeæ 
foliolis integris lanceolatis ad medium gynostegii adnatis 
eumque subæquantibus.—Sierra Leone, Vogel. 
Folia fere M, Leonensis, at minora. Cyme pedunculate, den- 
sifloræ, minus tamen confertze quam in M. tenuissima. Co- 
rolle lineam longæ, fere globosæ (tandem rotato-expansæ ?) 
profunde 5-fidæ, intus omnino nudæ. 
1. Gymnema subvolubile, Dene. in DC. Prod. 8. p. 621.—Cape
