Bhotan and Mishmee. The areoles are much more numerous 
than in stigmosus, and the included veinlets also more numerous, bin 
much less anastomosing, the fronds in my specimens are of thinner

8. NiPHOP.OLUS Fissus. {BL) Rhizome creeping, paleaceous

nose-coriaceous 6 inches to a foot 
and more long, \ an inch to i-if 
inch wide, lanceolate or linear-lan- 
ceolate or even linear, often finely 
acuminated, the margin quite entire 
(or rarely spuriously and very un- 
equally pinnatifid with remote long 
and narrow segments), from near

NiPHOBOLus FISSUS. (BL) with the sori ; venation quite sunk, 
veins pinnate but not pron.inent, venules transversely parallel and 
forming with the veins parallelogrammoid areoles (about five between 
costa and margin), with two, sometimes only one, excurrent free 
clavate veinlets in each areole ; sori copious and at first quite sunk 
among the tomentum appearing in the form of small tubercles, at 
length a circular opening appears, but the sori scarcely rise above the 
surface of the tomentum, arranged in series. BL Fil. Jav. p. 58, t.
