less deflexed and abbreviated; largest pinnulae linear-lanceolate, about 

 12' J cm. long by 2% cm. broad, gradually acuminate, the acumen 

 obliquely serrate-dentate, the edge cut about 'j^-^&y down to the costa, 

 the base truncate or subcordate-truncate, not rarely slightly narrowed, 

 the costa brown-hairy above, sparingly and deciduously subulato-squamulose 

 beneath, the costulae and veins naked. Lobes or lobules somewhat oblique, 

 rather close, blunt to truncate, the largest 5 — 6 mm. each way, crenate- 

 dentate at the apex. Texture firm-herbaceous; surfaces naked; upper 

 surface dark, lower paler; costulae pinnate in the lobes; veins to + 6 on

 This species has the rachises not rarely tomentose, and the fronds 



reddish-brown when dry. It differs principally from A. squamulata Hk. 

 by the often, though not invariably, conspicuously V-shaped rows of sori 

 (especially in the typical form) and the polished, reddis-black stipe and 

 main rachis, and in having the pinnulae cut rarely more than '.^ -way down 

 to the costa into mostly crenate or serrate lobes with 4 — 5 veins on a side.
