An undershrub, branched from the base ; branches decumbent

with pale subfulvous gland-tipped spreading hairs, more or less 
leafless sub-glabrate and scattered with dusky specks below, spiny

oblanceolate, pointed at the apex, much attenuate to the sessile

MossAMEDEs.—In gravelly places by the river Maiombo at a place

This should be compared with A. arenarium Engl., l.c., and A. 
scaberrimum Schinz, l.c., p. 185, the types of neither of which have I 
seen ; from the former it differs by the size and other characters of 
the foliage, and from the latter by its less scabrid scarcely acute leaves.
