i2 3. ALSOPHILA. 



Dentose above, the tomentum dark-reddish-brown. Pinnae ± crecto-patent, 

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

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

 talked, + 25 on each side, distant, the lowest longest or sometimes somewhat 

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

 vith the apex acuminate, toothed, the base ti-uncate, the edge broadly crenate 

 r lobed to '/s^^^y down, the lobes or crenations entire, crenate or denti- 

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

 ostae and veins distinct, dark-coloured ; main veins pinnate, veins simple, 

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

 ather near the costa, on the lower 1 — 2 veins, sometimes in 3 — 4 rows, «e* 

 whether or not divaricating.

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

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

 he base, 3-pinnatiiid, to 3 M. long. Pinnae stalked, 45 — 60 c.M. long or 

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

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

 )ase truncate, the edge pinnatifid + '/s — Va'^^Y down to the costa. Lobes 

 riangular or rounded, crenate or serrate.- Texture membranaceo-subcoriaceous ; 

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

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

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