ASPLENIE.^ — ASPLEXIUM. 79 



I am unable to locate Thamnopteris stipitata Presl, collected in Luzon 

 by Cuming 195. 



(2) A. scolopendrioides J. Sm. Rhizome 8 mm. in diameter, clothed 

 with lanceolate, broA\Ti chaff; stipe 2 to 4 cm. high, scaly or almost naked, 

 passing insensibly into the attenuate base of the frond; fronds 40 to 50 

 cm. high, 3 to 4 cm. broad, apex caudate, margin entire, texture subco- 

 riaceous; veins oblique, usually simple, rather remote; sori reaching from 

 the midrib to within 6 mm. of the margin; edge of the indusium leaving 

 a distinct ridge on the lamina where it dehisces. 



Philippines, Cuming 318; Baco River, Mindoro, Merrill 1810. (This de- 

 cription adapted to Merrill's plant.) 



The fern of DeVore and Hoover 329, from Mount Apo, differs most 

 conspicuously in the indusium's leaving no prominent line where it 

 dehisces, but the material in hand does not justify its description as a 

 new species. 



(3) A. squamulatum Blume. Stipe tufted, 5 to 10 cm. long, scaly 

 below; frond lanceolate, 30 to 70 cm. long, 4 to G cm. broad, acuminate, 

 base gradually attenuate to the stipe, entire or nearly so, lamina coriaceous, 

 glabrous, midrib somewhat chaffy; veins inconspicuous, as a rule free; 

 sori reaching from near midrib to within 1 cm. of the margin. 



Southern Luzon, Baranda; ]\Iontalban, Loher; Todaya, Davao, 1,200 m., 

 Copeland 1201, 1288. 

 Java, Borneo. 



(4) A. apoense Copeland. Rhizome very short, erect; stipes clustered, 

 stout, scaly, 1 to 5 cm. high, passing insensibly into the attenuate base 

 of the frond; costa stout, scaly; frond 20 to 35 cm. high, 1.5 to 2.5 cm. 

 broad, entire, acute, glabrous, coriaceous; veins inconspicuous, erecto-patent, 

 usually forked; sori linear, reaching two-thirds of the way from the costa 

 to the margin. 



Mount Apo, Mindanao, 1,800 m., Copeland llOS; epiphytic in clumps. 



(5) A. vittaeforme Cav. Rhizome creeping, naked; stipe short, erect, 

 naked; frond lanceolate, 30 to 45 cm. long, 4 to 8 cm. broad, narrowed 

 to an acute point and very gradually into the stem below, the margin 

 obscurely toothed; texture coriaceous; veins simple, close, nearly horizon- 

 tal, the copious sori often reaching from the midrib nearly to the edge. 



Davao, Warburg 14112; southern Luzon, Baranda. 



Java, Fiji. 



The stipes are jointed to the rhizome, as in Polypodium. 



(6) A. epiphyticum Copeland. Rhizome scandent, bearing scattered, 

 minute scales; stipes about 8 cm. long, clothed with minute ferruginous 

 scales; typical fronds simple, 20 to 30 cm. high, about 4 cm. wide, 

 acuminate, base ol)tuse or subacute, margin serrate or crenate, texture 

 membranaceous; costa stout, like the stipe; lamina glabrous; veins conspic- 

 uous, usually forked, almost transverse; sori linear, toucliing neither oosta 

 nor margin; yovniger plants bear fronds bi-tri-pinnati-dissected; and tliere 

 are inteniu'diate forms. 



Davao. Miiidimjio, cpipliytic on trunks in coast forest, Copeland 004.
