THE BOOK OF CHOICE FERNS. 



The spear-shaped fronds (Fig. 108) of this species, 2in. to 6in. long 

 and pinnate, are produced from a clustered rootstock. They are provided 

 with stalkless, blunt, oblong leaflets, broader at the base, slightly hairy 

 above, and deeply cleft into many oblong, obscurely-toothed lobes of a dull 



green colour. The rachis (stalk of 

 the leafy portion) and the secondary 

 midribs have their under- side clothed 

 with reddish, chaffy scales. — Hooker,

A small-growing species, of little decorative value, native of China. — 

 Hooker, Synopsis Filicum, p. 47. 



W. lanosa — la-no'-sa (woolly), Hooker. 



This distinct species is a native of Northern India ; it has been found on 

 the mountains of Kumaon at 11,000ft. to 12,000ft. elevation, and in Sikkim 

 at altitudes varying between 14,000ft. and 16,000ft. Its oblong, pinnate 

 fronds are quite shaggy with copious, soft, long, rusty-coloured hairs, mixed 

 with very narrow, long, chaffy scales. The leaflets, somewhat heart-shaped 

 and toothed, are scarcely cleft again. This plant has much the appearance of 

 a densely-woolly form of W. hyperborea. — Hooker, Synopsis Filicum, p. 47.
