2o6 Ferns of British India and Ceylon. 
6. PoLYSTicHUM iLiciFOLiUM. {BoH.) Stipcs densely tufted, 
2-4 inches long, clothed with large scales throughout ; fronds linear 
or lanceolate, not attenuated at the base, very coriaceous, pinnate ; 
pinnae either small simple triangular or subrhomboidal, or much 
larger and again pinnate, naked on both sides and shining, angles spinu- 
lose-mucronate ; rachis fibrillose ; sori mostly in two rows, usually large; 
indusium peltate ; veins immersed. Don. Frod. Fl. Nep. 2,- Hook. 
Syn. Fil. 251. Polystichum stimulans (Kze.), Bedd. F.B. I. t. 31. 
Himalayas, from Chumbra to Sikkim, 7,000-11,000 feet 
elevation. 
The smaller forms with simple pinnae are very distinct, but the 
larger ones with the pinnae again pinnated, quite graduate into 
P. aculeatum, var. rufo-barbatum till it 
becomes quite indistinguishable from 
forms of that fern, and is probably only 
a variety of it. 
7. Polystichum Thomsoni. {Hook.) 
Stipes tufted, 2-4 inches long, fibrillose ; 
fronds pinnate linear up to 7 inches 
long, subcoriaceous, not gradually atten- 
uated at the base, both surfaces more or 
less fibrillose ; pinn^ cut down almost to 
the rachis, bristly serrate, very unequal at 
the base, the lower margin being cut away, 
POLYSTICHUM ILICIFOLIUM. the uppcr wlth the basal lobe much en- 
{Do7t.) larged ; veins pinnate or forked in the 
segments ; sori terminal on a veinlet ; indusium peltate, bluntly 
crenated or subentire. Hook. Syn. FiL p. 251, and 2nd Ce?it. Ferns, 
A 25, in part only. Bedd. F. B. I. t. 126. 
Himalayas; from Balti to Sikkim, 7,000-13,000 feet elevation. 
Very near the smaller forms of Prescottianum, but the stipe is 
fibrillose, not scaly. Hooker's plate is taken from specimens of 
both species, and it is very probable that they are only varieties 
of the same plant.
