68 3. ALSOPHILA. 



Fronds lanceolate, probably 1 74 — 1 % m- long by '/a m- broad, 3-pinnatifld, 

 abruptly acuminate, rather narrowed at the base. Pinnae ± 8 — 9 on a 

 side, horizontal or spreading, remote, alternate, lanceolate, the central 

 ones the largest, ± 26 cm. lang, abruptly acuminate, the higher sessile, 

 the lower + 10 cm. long, petiolate. Pinnulae petiolulate, pinnatifld, 

 triangular-lanceolate, the largest ± 7 cm. long and 1 'z, cm. broad. 

 Segments approximate, linear-falcate, + 1 cm. long and '/s cm. broad, 

 serrate, obtusate. Texture chartaceous; surfaces naked; upper surface 

 dark-green, lower paler ; rachis muricate, fusco-pilose ; costae fusco-pilose 

 above, beneath when young clothed with short, fuscous hairs and fer- 

 rugineous, ovate, long-acuminate, ciliate scales; as are the costulae which 

 are naked above; veins forked. Sori + 10 on a side, near the costulae, 

 the lower somewhat divaricating.

[26d} A. wengieiisis, Bfuu., in Engl. Bot. Jahrb., IL, 13, flg. 1 C. 



Fronds 3-pinnatifid. Pinnae sessile, lanceolate, 39 cm. more or less 

 long, 12 '/a cm. broad, sUghtly narrowed at the base. Pinnulae remote, 

 triangular-lanceolate, the central ones the largest, + 6'/2 cm. long, I'j^ 

 cm. broad at the base, shghtly acuminate, deeply pinnatifld; lobes sub- 

 falcate from a slightly dilated base, + 8 mm. long and S'/^ mm. broad, 

 entire or subcrenulate in the lower part, serrate towards the bluntish 

 apex. Texture chartaceous; surfaces naked; rachises muricate, above 

 densely brown-hairy, when young beneath short-hairy and brown-scaly, 

 glabrescent; costae densely hairy above, sparingly hairy and buUato- 

 squamulose beneath; costulae naked above, sometimes sparingly hairy 

 and buUato-squamulose beneath; veins + 12 on a side, simple or forked. 

 Sori mostly occupying the upper part of the lobes, 5 — 7 on a side, the 

 lower medial, the higher nearer the costula than the edge; sporangia 

 intermixed with setiform paraphyses.
