6. Ckeilantkes Dalhousice, (Hook.) Roots tufted, stipites rather short, ebeneous glossy, deciduously scaly, fronds about a span 
long, deltoidly lanceolate, glabrous on both sides, and perfectly free from powdery substance beneath, pinnate, the apex deeply pinnatifid 
and acuminate ; pinna3, upper ones lanceolate pinnatifid, the rest broader and bi-pinnatifid, lowest pair very broad at the base with their 
lowest inferior segments (or pinnules) much longer than the rest, the margin crenated, sometimes in the barren portions ciliated, involucres 
brown scariose reniform close, but generally distinct, sometimes confluent and then less ciliated, but lobed and jagged. Hook. 
,Sp. Fil. ii, 80. 
Very nearly allied to C/ieUanthes farinosa, but always destitute of powdery substance— its fronds are larger and more 
membranaceous.

So7'i superficial, non-indusiate, the receptacles occupying the whole under-surface, or both upper and under-surface of the 
rachiform fertile fronds. Veins simple or forked, or pinnate from a central costa ; venules simple or forked, free. 
Fronds dimorphous, pinnate, or bi-tri-pinnate, the fertile with linear contracted segments. Rhizome creeping or scandent. In 
this genus occurs the highest degree of development of which Ferns seem susceptible. The whole of the under-surface (and in some 
species the whole surface both above and below) is sporangiferous, (Moore.) 
1. Poliihotrya appendicidata, (J. Sm.) Rhizome thick, short creeping, stipes and rachis scaly ; fronds pinnate glabrous, the 
sterile ones viviparous at the apex, pinnae 25 to 50 pair, sub-opposite or alternate oblong lanceolate obtuse, 2 to 3 inches long, | an 
inch broad, rather deeply crenated with a setaceous bristle between each crenature, superior basal crenature the largest, inferior base 
cuneate and slightly unequal, veins pinnate free, fertile fronds much contracted, pinnae much shorter than the sterile ones.

2. Pohjbotnja aspleniifoUa, (Bory.) Rhizome thick, short creeping, stipes and rachis very scaly, fronds pinnate glabrous, 
sometimes viviparous at the apex ; pinn» 25 to 50 pair opposite or alternate, oblong obtuse very unequal sided (the inferior basal 
portion being, as it were, cut away) pinnatifid nearly \ way to the costa, with a setaceous bristle between each segment, upper basal 
segment the largest and crenate or serrate, others entire or crenulate, veins pinnate free, fertile fronds much contracted, pinnfe much 
shorter than the sterile ones. 
Closely allied to the preceding species, but easily distinguished.
