than the species with larger sessile or sometimes shortly stalked leaves, up to

the leaf-hase.—Z. kamerunense, Engl. l.c. 125.

2. E. paiveanum, Wedd. in DC. Prodr. xvi. i. 178. A moncecious 
or dicecious herb similar in habit to F. Welwitschii ; stem about a 
foot high, glabrescent, or pubescent in the upper younger portion. 
Leaves membranous, subsessile or shortly stalked, obliquely elliptic, 
apex abruptly acuminate, base unequal, on the broader side 
auriculate, on the narrower tapering rapidly and joining the petiole 
about 2 lin. above the origin of the wider half, margin serrate or 
dentate-serrate throughout, 3-5 in. long, 14-2 in. wide, lateral nerves 
on the broader side 6-8, the lowest short, the second from the base 
on the narrower side running parallel with the margin beyond the 
middle of the blade, upper face glabrous or with a few pointed 
appressed hairs, and with numerous linear cystoliths, lower face 
More or less pubescent on the prominent nerves, rarely glabrous ; 
petiole up to 3lin. long. Stipules lanceolate-acuminate to subulate,
