cylindrical neck, passing above into a pair of long narrow spine-tipped 
outgrowths, overtopping the two stigmas. 
Upper Guinea. Senegal, Leprieur (ex Rendle). 
Described from a specimen in the Cosson Herbarium at Paris. Clearly allied to 
N. Welwitschii, Rendle, from which it is distinguished by a less lax habit, the tuft- 
like dense-leaved terminal branchlets, the more regularly toothed spreading firmer 
leaves, fimbriate leaf-sheath, and the pair of terminal outgrowths on the female 
spathe.

times lax, sometimes bushy, with all intermediate states. Leaves 
variable in length, generally bent backwards, with 10-20 teeth on the 
margins; sheaths rounded-truncate, with 5-8 prominent teeth on either 
shoulder. Male and female flowers often alternating in the leaf-sheaths ;

the mouth; female flowers about 14 lin. long. Ovary sessile, about 5°; 
lin. long; style long; stigmas 2, unequal. Fruit linear-oblong,
