lateral, either on a fertile stem or on a separate stem (which, however, might 
■develop ultimately a terminal $ flower) ; they are also occasionally basal. 
They are rather large and numerous. The leaf-cells are unusually elongate 
and rather large, with thin walls.

§ Semilimbidium. Autoicus. Flores masculi foliorum axillis siti. 
Pusillus, viridissimus ; folia plurijuga, hand nitida, madida complanata, 
frondem circa 1*5 mm. latam instruentia., sicca fortiter incurvo-falcata ; 
•oblonga, haud acuminata, acuta vel subobtusa et apiculata. Costa sat 
angusta, pellucida, percurrens vel brevissime excurrens. Lamina dorsalis 
ad basin costae sat abrupte desinens ; lamina vaginans tantum optime, late 
(praecipue in foliis caulis fertilis) limbata, ceterum marginibus valde regu- 
lariter crenulatis. Cellulae distinctae, opacae, perchlorophyllosae, 5-6 /x latae, 
hexagono-rotundae, utraque pagina altissime spicidoso-papillosae. Seta 3 mm.

A distinct species, differing markedly from most of the African species 
of this section in the small size, the leaves broadly pointed and not at all 
acuminate, the highly crenulate margin, and especially the cells, which are 
not obscure as in most of the species, but well defined, although opaque, 
and are very strikingly papillose, the papillae being dense, highly elevated 
and spiculose, usually in fact exceeding in height the diameter of the 
individual cell.

In the type the leaves are acute, variously pointed, with the nerve mostly 
percurrent.

(No. 315). There is sometimes the faintest possible trace of border on the 
vaginant lamina, but it is practically negligible.
