﻿32 3. ALSOPHILA. 



mentose above, the tomentum dark-reddish-brown. Pinnae + crecto-patent, 

 stalked, 40 — 60 c.M. long, with a terminal segment, which is pinnatifid at 

 the base, toothed towards the acuminate point. Pinnulae spreading, short- 

 stalked, ± 25 on each side, distant, the lowest longest or sometimes somewhat 

 shorter than the next higher ones, ± 7 — 10 c.M. long, 10 — 15 m.M. broad, 

 with the apex acuminate, toothed, the base truncate, the edge broadly crenate 

 or lobed to Vs"'^*! down, the lobes or crenations entire, crenate or denti- 

 culate. Texture coriaceous ; colour dark above, paler beneath ; surfaces naked ; 

 costae and veins distinct, dark-coloured; main veins pinnate, veins simple. 

 Sori large in 1 row medial between the costa and the margin or in 2 rows 

 rather near the costa, on the lower 1 — 2 veins, sometimes in 3 — 4 rows, not 

 divaricating.

Stipe more or less rough, scaly at the base, and as well as the main 

 rachis reddish-black, polished. Fronds oblong-lanceolate, hardly narrowed at 

 the base, 3-pinnatifid, to 3 M. long. Pinnae stalked, 45 — 60 c.M. long or 

 longer, the apex acuminate and pinnatifid. Pinnulae linear, acuminate, (upper 

 ones sessile, lower ones petiolate), 7 — 15 c.M. long, 12 — 24 m.M. broad, the 

 base truncate, the edge pinnatifid + Vs — V2"way down to the costa. Lobes 

 triangular or rounded, crenate or serrate. Texture firm, but not coriaceous; 

 rachises often scaly or lomentose above; surfaces naked; veins simple, 5 — 6 

 on each side of the costulae. Sori dorsal on the veins, mostly arranged in 

 the shape of a yy, not extending to the apices of the lobes.

Fronds large, deltoid, 3-pinnatifid; main rachis naked, black-brown, un- 

 armed. Pinnae oblong-lanceolate, the lowest + 30 c.M. long; rachis brown, 

 hairy above. Pinnulae sessile, linear, subobtuse, 3V2 — 5 c.M. long, 10 — 15 

 m.M broad, the base truncate, the lower ones pinnatifid + V2"Way down to 

 the costa. Lobes oblong, entire. Texture rigid; surfaces naked; main veins 

 pinnate in the lobes; veins 4 — 6-jugate, conspicuous, curved, ascending, simple 

 or the lower ones forked. Sori medial.
