Kashmir; Sind valley, alt. 8000 feet, H. C. Levinge, once collected.—Distrib. Alpine 
: and Arctic Europe and North Asia. 
Fronds 5 by i-$ in.; lowest pinn 4 in. distant. Pinns ovate and cordate-ovate, 
crenate with rounded lobes; needle-like hairs plentiful near the sori, few on other por- 
tions of the lower surface of the pinna. H. C. Levinge's example is W. hyperborea 
type, in nowise verging towards Woodsia lanosa.

Like W. hyperborea, but the frond densely ferruginous, lanate beneath. The stipe is 
also villous or lanate in all the examples, though Beddome figures it glabrous; but the 
wool is deciduous, and seems likely to disappear altogether in age.

Himalaya; from Dhurmsala to Sikkim, alt. 8000—12,000 feet, frequent. 
Frond 9 by 1-14 in., narrowly oblong; sori globose, much elevated; involucre thin 
but persistent, globose (though torn) in the over-ripe fronds.

Nepaul and Bhotan; alt. 6000-10,000 feet, plentiful. Khasia; alt. 4500-6000 feet, 
plentiful.—Distrib. Western Ghats, fide Bedd. l. c. 25. 
Main rhachis clothed with lanceolate-acuminate scales, and also laxly pubescent. 
Aspidium spectabile, Wall. Cat. 372, is Lastrea pulvinulifera, Bedd., mainly ; but some 
Peranema has got mixed. The two (when without fruit) are difficult to separate; but 
Aspidium spectabile has the rhachis (exclusive of the scales) nearly glabrous.
