collects; exsicc, sched. No. 247 (nomen). 
Monoicous. Plant rather small, green oi* pale-green, densely 
stratified, corticolous. Stem up to 2 cm. long, sparingly branched. 
Leaves subopposite, distichously patulous, oblongo-conical, with 
margins straight, at apex not half as wide as at base, at apex 
lunately excised, bispinose, the spines being short and nearly of 
equal size and narrowly triangulate. Leaf-cells 28 //., at base 28 
by 37 fx; trigones minute. Amphigastria three times as wide 
as the stem, widely lunately excised, on each side bispinose and 
broadly united with the leaves. Perianths terminal, i.e. not 
borne on innovations, oblongo-triquetrous, at apex deeply multi- 
Liciniate, broadly winged, the wings being irregularly and grossly 
spinose. Innermost floral leaves little larger than the cauline, 
at apex truncato-bidentulous, with margins paucidenticulate. 
Innermost floral amphigastrium small, broadly connate with its 
proper leaves, subquadrate, quadrilaciniate to half its length, the 
innermost lacinise being the stouter. Androecia terminal on the 
branches, fusiform ; bracts exciso-bifidulous to one-third of their 
length and inflatedly lobulate on the postical side, the lobules 
being united with the amphigastrium. 
The original specimen was gathered on the Cameroon mountains 
above the village of Buea at an elevation of about 5200 ft., on

trigones rather large. The other parts of the plant are wanting.
