COPELAND. 
Asplenium tenerum Forst. 
In humid forests at 140 m. alt. (No. 5894). 
Common in the Philippines from northern Luzon southward. 
India to Polynesia. 
Asplenium persicifolrum J. Sm. 
Epiphytic in humid forests at 140 m. alt. (No. 5893). 
Previously accredited to Luzon and Bohol; Mount Banajao, ( Elmer 7968). 
Asplenium Lepturus J. Sm., Presl. 
Epiphytic at 900 m. alt. (No. 5890), a small form; and in the ridge forests 
at 1,700 m. alt. (No. 5891), very large. Both numbers have more copious sori 
than are common in the contiguum group. 
Already collected in Luzon and Palawan. 
Asplenium laxivenum Copel. n. sp. (A. contiguum var. bipinnatifidum Christ in 
Bull. Herb. Boiss. 6 (1898) 152, non Baker). 
Ehizomate breve, 6 mm. crasso, stipite griseo-b'runneo, 30 cm. alto, 
sparse paleaceis; fronde 40-50 cm. alta, 12-15 cm. lata, acuminata; pin- 
nis brevi-pedicellatis, ca. 7 cm. longis, 15 mm. latis, caudatis, plus 
minus profunde crenato-incisis, segmento primo acroscopico pleurumque 
libero, i. e., pinnulo, orbiculari-cuneato, supra inciso-crenato, subcoria- 
ceis, glabris, venis furcatis, paucis, perobliquis, 1-2 mm. remotis, soris 
costae quam margini propioribus. 
Insigniter variat., ad terrain in silva museosa, 1,350 m. s. m. (No. 5892). 
The best constant character of this fern is the extremely lax venation. The 
stalked pinnae distinguish it from A. anisodontium. Besides the above number, I 
would include here the following specimens: 
Luzon, Mount Data, alt. 2,200 m. (Copeland 1857), with shorter subacute 
pinnae; Baguio ( Elmer 6012), with sometimes a free basiscopic pinnule. Min- 
danao, Mount Apo (Copeland 1598c), deeply cut throughout. 
Asplenium pellucidum Lam. (A. hirtum Kaulf.). 
Terrestrial in forests at 700 m. alt. (No. 5888), and epiphytic in forests at 
1,800 m. alt. (No. 5889). 
More than one Philippine species has been included under this name. This 
form is rather widespread. 
Asplenium cuneatum Lam. 
Epiphytic in ridge forests at 900 m. alt. (No. 5887). 
Mount Maquiling, Luzon (leg. Loher) and Mindanao. 
Asplenium affine Sw. 
Epiphytic in humid forests at 140 m. alt. (No. 5886). 
Central Luzon and Mindanao. 
East Africa to Polynesia. 
Asplenium laserpitiifolium Lam. 
Epiphytic at 900 m. alt. (No. 5885). 
Throughout the Philippines.
