spreading, blunt lobes, the lower ones of which are much reduced. The 

 leaflets are of a somewhat leathery texture and have the sori (spore masses) 

 disposed in a close row near the midrib. — Hooker^ Synopsis Filicum, p. 263.

This stove species, of medium dimensions, native of the West Indies, is 

 particularly distinct on account of the bright golden colour of the long, 

 narrow scales with which the stalks, about 6in. long, are densely 

 clothed. The fronds, IJft. to 2ft. long and 6in. to 9in. broad, have their 

 leaflets Sin. to 4in. long, about lin. broad, and cut down to the rachis (stalk 

 of the leafy portion) into narrow-oblong lobes ; they are of a soft, papery 

 texture, and have their under-side naked, but the rachises are, like the stalks, 

 furnished with bright golden-coloured, narrow scales. There are seven or 

 eight veinlets on each side, and the sori (spore masses) are disposed in 

 a row on each side of, and close to, the midrib. — Hooker^ Species Filicum, 

 iv., p. 101, t. 246. 



N. (Lastrea) barbigerum— Las'-tre-a ; bar-big'-er-um (bearded). Hooker. 



A greenhouse species, of medium dimensions, native of the Himalayas. 

 According to Beddome, it is found in Kumaon, Simla, and Sikkim, at altitudes 

 varying between 12,000ft. and 13,000ft. Its fronds, borne on tufted stalks 

 6in. to 12in. long and densely clothed with large, bright brown scales, and 

 soft, silky hairs, are 2ft. to 3ft. long and 6in. to 12in. broad. The spear- 

 shaped leaflets, 4in. to 6m. long and l^in. broad, are closely set and divided 

 mto oblong, blunt pinnules (leafits), the lower ones deeply cleft into lobes 

 copiously furnished with awned teeth, and with their edge often incurved. 

 The texture is soft and papery. The sori (spore masses) are disposed in 

 rows close to the midrib of the pinnules. — Hooker, Species Filicum, iv., p. 113.
