TzNITIS optTusA, Hook. 
Glabra coriacea nitida, frondibus simplicibus oblongo-ovatis 
obtusis brevissime mucronatis, soris intra marginem in- 
crassatum et costam continuis (infra apicem etiam) vel 
interruptis, stipite gracili filiformi basi piloso, caudice 
repente crinito. 
- Borneo, near Sarawak, Mr. Thos. Lobb. 
The genus Tenitis has been of late properly considered to 
be confined to one species, 7! blechnitis, and that is a pinnated 
species. Our present plant is a true Tenitis, with a simple 
frond, and quite entire at the margin, except from the effect 
of injury. In all our fronds too, where the apex is uninjured, 
the two lines of sori are united or continuous within the apex, 
the only portion invariably free from sorus being at the very 
base. The plant is peculiarly rigid and coriaceous, glossy, 
the margin thickened. The caudex is creeping, but rather 
slender, and clothed with dark brown, glossy, crinite scales.
