A NEW LASTREA FROM ASSAM. 

 By C. W. Hope. 



Nephrodium (Lastrea) Mannii, n. sp.' — Rhizome suberect (?), 

 clotbed with nearly linear, pale-brown, hair-pointed scales ; stipes 

 tufted, very long, longer even than frond, stiff, wiry, and, together 

 with the main rachis, channelled deeply on upper side and slightly 

 on under side ; stipe and main r-achis densely clothed to within a few 

 inches of apex of frond with hairy scales (or hairs), three-eighths 

 of an inch and less in length, changing rapidly upwards from the 

 colour of those on the rhizome to very dark brown ; frond oblong- 

 lanceolate, truncate at base, 18f in. long, 6£ in. broad halfway up, 

 increasing to 9J in. at base, upper half lanceolate, gradually 

 acuminate ; pinna narrow, oblong, slightly falcate, acuminate 

 towards tip, about 12 pairs distinctly stalked, above which the 

 lowest pinnule on lower side becoming decurrent on main rachis, 

 upper 20 or more pairs sessile, distance between pinnre gradually in- 

 creasing downwards to 1£ in. ; lowest pair of pinnae slightly the 

 longest, nearly 5 in. long ; pinna? of lower half of frond bipinnate 

 for part of the way up (i. e., towards base cut down quite to the 

 rachis and with intervals between the/ pinnules), as to the rest of 

 the frond to within 4 in. of tip cut down to rachis but for a distinct 

 si?ws between each into oblong, falcate segments, unequally rounded 

 at point, decurrent on rachises ; pinnae f in. and rather more wide at 

 base of frond, scarcely diminishing in width till near the apex ; 

 pinnules of segments ^ths of an inch long by ^ths broad, entire 

 in the upper part of the frond and becoming gradually lobed (most 

 so on lower side) towards the base, not anywhere toothed at apices ;
