3. ALSOPHILA. 67 



ed with dark-brown, minutely ciliate-serrate, setiform scales 2'l^ — 3 cm. 

 long and % mm. wide. Fronds (incl. the ^tipe) 2 — 3 m. long. Pinnae ± 

 60 cm. long, + 25 cm. broad, subsessile, acuminate. Pinnulae + 13 cm. 

 long, + 2'.^ cm. wide, acuminate, sessile, close, pinnate near the base; 

 segments subfalcate, obtuse, + S'/j mm. wide, serrulate, separated by 

 narrow sinuses, the lowest not adnate. Texture herbaceo-coriaceous ; both 

 surfaces green, naked; main rachis stramineous beneath, beset with small, 

 sharp spines with black, mammiform bases, scurfy with minute, rather 

 deciduous squamules; secondary rachises tawny beneath, finely prickly 

 and deciduously squamulose; costae bearing pale hairs above, and beneath 

 2 kinds of stramineous scales : minute (? bullate) ones which are ciliate or 

 subentire, and larger, lanceolate ones which are strongly lacerate into brown 

 setae; costules beneath bearing pale, bullate squamules and hairs; veins 10 — 

 12 on a side, mostly forked below the middle. Sori in the forks of the veins.

Stipes spinose, castaneous, clothed towards the base with glossy, 

 castaneous, caducous, linear-subulate scales; main rachis giabrescent, 

 spinulose, the upper part castaneous and tuberculate, as are the secondary 

 rachises. Pinnae + 45 cm. long, 9—11 cm. broad, horizontal, sessile, 

 acute, the rachis velutinous above, naked beneath, with the base thickened 

 and pilose, provided with a pale spot on the upper side; lowest pinnae 

 stalked, reduced, deflexed, narrowed at both ends. Pinnulae numerous, 

 sessile, horizontal, often straight, cut down hardly to the costa, 9 — 11 

 mm. broad at the base, narrowed gradually towards the serrate apex ; 

 costae above velutinous towards the base, beneath densely clothed with 

 ovate, stramineous or castaneous scales. Lobes approximate, subfalcate, 

 + 2 mm. broad, obtuse. Texture herbaceous; surfaces naked; under 

 surfaces paler than the upper; costulae paleaceous at the base beneath; 

 lower veins forked, higher simple. Sori costular, occupying the forked 

 veins, contiguous, confluent.
