deltoid and bi- or tripinnatifid (in shape of the Greek delta, A, and twice or 

 thrice divided half-way to the midrib), are 2ft. to oft. long, and furnished 

 with spear-shaped leaflets 9in. to 12in. long, the stalks of which are densely 

 covered with scales of a reddish-brown colour. The round and numerous but 

 small spore masses are disposed in one row on each side of, and close to, the 

 midvein of each fertile leant. — Nicholson, Dictionary of Gardening, hi., p. 190.

 (having a downy foot or stalk), W allien. 

 This greenhouse species, native of Northern India, and found, according 

 to Beddome, in Nepaul and Khasya at elevations varying between 4000ft. and 

 6000ft., in Simla and Kumaon at 7000ft., and in Sikkim up to 11,000ft., is 

 totally distinct from the preceding one. Its simply-pinnate fronds, produced 

 from a wide-creeping rhizome densely clothed with black, bristly scales, and 

 borne on slender, naked stalks 2in. to 4in. long, are of a flaccid nature, 1ft. 

 to If ft. long, 3in. to 4in. broad, and cut down nearly or quite to the rachis 

 into slightly-toothed leaflets of a soft, papery texture, and naked on both 

 sides. The spore masses are disposed in single series. — Hooker, Species 

 Filicum, v., p. 25 ; Second Century of Ferns, t. 52. Beddome, Ferns of

A stove species, native of Java, with a wide-creej)ing rhizome and 

 pinnatifid fronds of a somewhat leathery texture, 1ft. to l^ft. long, 1ft. or 

 more in breadth, cut down throughout to a narrowly- winged rachis into 

 sharply-pointed lobes, slightly undulated at their edges and naked on both 

 sides. The sori (spore masses) are immersed and disposed in one row on 

 each side of the midvein.— Hooker, Species Filicum, v., p. 87.
