Leaves shorter and broader than in O. affine, evidently — 
acuminate, more widely areolated, strongly revolute at the 2 
margins. Calyptra slightly pilose, straw-coloured, tipped with i 
deep brown (but greyish-green in O. affine). Vaginula smooth. — 
Pedicel not exceeding the vaginula, tapering into the collum. - 
Capsule wider and rather shorter than in O. affine, mote 
widely striated. Cilia linear, of a double series of cellules, 
scarcely equalling the teeth. Operculum equalling or €x- 
ceeding that of O. affine. Ww 
O. stramineum (described in the Bot. Society's Transat- — 
tions) bears great external resemblance to O. fastigiatum, but — 
differs in the greener, narrower leaves; the scarlet-tipped : 
calyptra (which indeed distinguishes it from all its allies 
except O. patens) ; the very hairy vaginula; the shorter cap- 
sule, when dry usually emersed or even exserted beÿon® 
the perichætial leaves, and with the sporangium less, ge 
collum more contracted; the much shorter operculum, not. 
margined with red ; finally in the subulate cilia, composed m 
a single series of cellules, and more frequently 16 than 8 1 
number. . z
