(3 of the calyx and 3 of the corolla). Fruit (immature) ovate, conically narrowed at 
the apex; scales in 18 series, yellowish near the base and with a broad intramarginal 
sharply defined band and a scarious brown fimbriate-denticulate margin, Seed . . »

OssrRvATIONS.—Of this species, which has remained more than 70 years unnamed in 
Herbaria and has not been found again by modern travellers, I have seen in the Paris 
Herbarium a specimen of a mule spadix, accompanied by two entire leaves, labelled: 
*Senegambia—M. Leprieur, 1830—Herbier d'Adrien de Jussieu, donnó au Muséum 
par ses enfants en 1857," and another specimen, apparently of the same gathering 
and with immature fruit, in Delessert’s Herbarium at Geneva. A third specimen, 
consisting of two partial female inflorescences and one leaf, is preserved in the Leyden 
Herbarium and was also gathered by Leprieur in Senegal. The leaflets of the female 
specimen in the Leyden Herbarium have a small and short but relatively strong 
spinule at their base on the upper side next to the rachis. This spinule is scarcely 
visible in the two leaves of the Paris specimens, which leaves are respectively 35 
and 40 em, long and are very similar to that of the above-mentioned Leyden 
specimen, but in one the leaflets are distinetly grouped, while in the other they 
are almost equidistant and with short vacant spaces only near the apex of the leaf, 
The mid-costa is sparingly spinulous above and quite smooth. beneath in both,

Description.—Slender, scandent.  Leaf-sheaths armed with scattered laminar rather 
small, 8-10 mm. long, black-tipped spines. Ocrea rather elongate, furfuraceous 
horizontally truncate, very sparingly spinulous at the base and not on the etes 
side. Leaves (in one specimen) 60 cm. long, not cirriferous; petiole rather long 
(18 em.) rather thick, subcylindric and wrinkled longitudinally when dry; armed 
irregularly all round with some straight, horizontal, rather strong, 1 cm, long, dark- 
tipped spines; rachis more or less fugaciously furfuraceous as is the petiole, rigid and 
relatively thick, acutely bifaced and smooth above, roundish beneath, where armed 
along the middle with solitary, straight, horizontal or slightly deflexed spines, which 
change into small claws towards the apex; leaflets rather many and crowded 
inserted at an angle of about 45°, interruptedly equidistant, viz. divided te 
groups by short vacant spaces, but equidistant in each group, papyraceous, linear- 
lanceolate, somewhat attenuate towards the base, gradually subulately acuminate io the 
apex, opaque, slightly paler beneath than above, their mid-costa acute and 
sparingly spinulous above or smooth on both surfaces; the secondary nerves slender 
and naked; the transverse veinlets sharp, much interrupted; margins rather closely 
spinulous; the largest leaflets, those a little above the base, 18-20 cm. long, 12-14
