ASPLENIE.E ASPLENIUM. 83 



the base, cuneate below, truncate-cuneate above; veins oblique, usually 

 forked, conspicuous, sori large, close to the midrib and reaching half way 

 to the margin. 



Davao, Mindanao, on rocky bed of Sibulan River, altitude, 700 m., 

 Copeland 983. 



The apex of fertile fronds often wanting. 



(20) A. hirtum Kaulf. Stipes tufted, 5 to 10 cm. high, strong, erect, 

 brownish, deciduously fibrillose; frond 30 to 60 cm. long, 10 to 20 cm. 

 broad, with very numerous horizontal pinnae on each side, which are 

 5 to 8 cm. long, 1 cm. broad, acuminate, broadly not deeply toothed, the 

 base on the upper side conspicuously auricled, on the lower side rather 

 suddenly but obliquely narrowed; texture coriaceous; rachis dark colored, 

 strong, more or less fibrillose; veins oblique (Syn. Fil. says inconspicuous; 

 Diels says evident) ; sori in two regular rows, which fall considerably 

 short of the edge. 



Mount Mariveles, Merrill 3760, Barnes; Mount Arayat, Merrill 3816, 

 Topping ; southern Luzon, Baranda; Mount Apo, DeVwe and Hoover 319. 



Madagascar to Polynesia. 



A. hirtum Kaulf. var. repressum Copeland. Differs from the type in 

 being smaller, less than 20 cm. high, almost sessile, and having obtuse 

 pinna?. 



Mount Mariveles, 1,200 m., on exposed ridges, Merrill 3212. 



Asplenium meyenianum Presl, Epim. Bot. p. 73, said to differ from 

 A. hirtum in the serration of the pinnae and the form of the pubescence 

 is probably not really separable from it. 



Manila, Meyen, Cuming 147. 



(21) A. anisodontum Presl. Stipes tufted, firm, erect, gray, naked 

 or slightly fibrillose; frond 30 to 45 cm. long, 10 to 15 cm. broad, with 

 numerous horizontal or subfalcate sessile pinnae on each side, which are 

 5 to 8 cm. long, 1 cm. broad, acuminate, inciso-crenate, the , base on the 

 upper side auricled and narrowed rather obliquely, on the lower side 

 obliquely truncate; texture subcoriaceous ; rachis firm, erect; veins oblique, 

 mostly once branched; sori parallel, in two regular rows, reaching nearly 

 from the midrib to the edge. 



Luzon, Cuming 128. 



Java. 



No. 334 of DeVore and Hoover, from Mount Apo (but from no such 

 altitude as their label states) may be A. anisodontum, but is serrate, 

 not crenate; many pinna? have a free lobe in the place of an auricle, as 

 A. Steer ei is described. 



(22) A. macrophyllum Swartz. Stipes tufted, 15 to 30 cm. high, stout, 

 erect, brownish, nearly naked; frond 15 to 45 cm. long, 15 to 30 cm. 

 broad, with 6 to 12 opposite pairs of stalked nearly horizontal pinna?, 

 which are 10 to 20 cm. long, 3 to 8 cm. broad, acuminate, sharply serrate, 

 the two sides nearly equal, but the lower one narrowed rather more 

 obliquely; texture subcoriaceous; rachis naked, firm, erect; veins very 

 oblique; sori in close long parallel lines reaching from the midrib nearly 

 to the margin.
