ASPLENIE^E ASPLEXIUM. 85 



lobed more than half way down to the rachis in the lower part, the two 

 sides unequal, the upper auricled and narrowed suddenly, the lower very 

 obliquely truncate at the base ; texture coriaceous ; rachis deciduously 

 villose; veins very oblique; sori subflabellate. 



Arayat, 800 m.; Tonglon, 2,250 m.; Mariveles, 1,400 m., and Montalban, 

 Loher, pinnae strongly auricled, resembling A. dimidiatum, but the point 

 acuminate; Xueva Vizcaya, Merrill 295; Baguio, Topping 266. 



Tropics, around the world. 



A., polyodon Forst., collected at Sorsogon by Haenke and in Laguna by 

 Cuming, and A. zamicefolium Presl, collected at Sorsogon by Haenke, are 

 hardly separable by the descriptions from A. caudatum. Tarachia trun- 

 catiloba Presl is also the plant commonly called A. caudatum on the 

 assumption that the real A. caudatum Forst. is not, as Presl states, 

 A. horridum Kaulf. 



(27) A. cuneatum Lam. Stipes tufted, 15 to 25 cm. high, firm, erect, 

 naked; frond 15 to 40 cm. long, 15 to 25 cm. broad, with numerous 

 spreading pinnae on each side, the lower ones 10 cm. long, 3 cm. broad, 

 lanceolate-deltoid, cut down to the rachis into several distinct ovate- 

 cuneate pinnules, which are inciso-dentate and cut down in the lower part 

 nearly or quite to the rachis; texture subcoriaceous ; rachis firm, grayish, 

 nearly naked; veins fine, conspicuous on the upper surface; sori linear, 

 subflabellate.

(28) A. affine Swartz. Stipe 15 to 30 cm. high, firm, erect, gray, nearly 

 naked; frond 30 to 45 cm. long, 15 to 30 cm. broad, with numerous pinnae 

 on eacli side, the lower ones lanceolate-rhomboidal, cut down to the rachis 

 into numerous distinct rhomboidal pinnules, which are again inciso-serrate 

 or deeply lobed; texture subcoriaceous; rachis firm, naked; veins sub- 

 flabellate; sori copious, linear.

(29) A. nitidum Swartz. Stipe stout, erect, grayish-black, naked; frond 

 6 to 10 dm. high, with numerous lanceolate-deltoid pinnae, the lowest of 

 which are 20 cm. long, 8 cm. deep, with numerous stalked subdeltoid 

 pinnules, which are again cut down to their rachis into broad, flabellato- 

 cuneate segments inciso-serrate round the outer edge; texture subcoria- 

 ceous; rachis stout, gray, naked; veins channeled, flabellate; sori short, 

 radiant.

This description covers two ferns. 



(30) A. laserpitiifolium Lam. Stipes tufted on an erect scaly root- 

 stalk, 20 to 40 cm. high, stout, erect, gray-black, naked; fronds reaching 

 a length of above 1 m., by one-third as broad, with numerous pinnae; the 

 lowest pinnae deltoid-lanceolate, with numerous stalked pinnules, the 

 lowest of which are again pinnate, and their segments incised or pin-
