PTEIUDOPHYTA HALCONENSES. 131 
venis in lineam signatam intraniarginalem anastomosantibus^ inter se 
1.4 nim. distantibiis; soris a costa y\ ad marginem attingentibus, inae- 
qualibiiSj venulis 1-2 inter soros sterilibus, indusiis brunneis, 1 mm. 
latis. 
In silva muscosa epiphytieum, 1,800 m. s. m. (No. 5901). 
Type from Mount Maquiling, Luzon, leg. Lolier. 
This fern combines the fructification of A. Phyllitidis and the stature of A. 
musaefoUum. My No. 1745 from Mindanao, doubtfully identified as A. Phyllitidis, 
is rather this species. More typical A. Phyllitidis occurs in Negros and Saniar, 
6 but even this is by no means identical with the Indian plant. 
Asplenium (Thamnopteris) colubrinum Christ in Bull. Herb. Boiss. II. 6 
(1906) 909, var. taeniophyllum Copel. n. var. 
Ehizomate 1 cm. erasso in substrate radienm foliorumque mortuorum 
imraerso; stipitibns confertissimis 2-5 cm. longis; fronde ca. 80 cm. 
longa^ 3 cm. lata^ acuminata^ deorsuni per alam longam siccam ad 
stipitem sensim attenuata^ integerrima^ coriacca^ glabra^ costa snpra 
biangulata deorsumque inter angulas concava, subtus vakle carinata, 
^ fragile, pleurumquc nigra; venulis inconspicuiis, inter se 1 mm. dis- 
tantibus, intra marginem anastomosantibus; soris a costa vix mediam 
laminam transeuentibus, plerumque venulis 2 inter soros sterilibus, in- 
dusiis ca. 0.3 mm. latis. 
In silvis epiphytieum, 700-900 m. s. m. (No. 5899). 
The type collected by Loher in central Luzon. 
Extast autem varietas hujus speciei frondibus interdum 4 cm. latis/ 
soris J-f ad marginem attingentibus, indusiis nigris, 0.6 mm. latis. 
In silvis eisdem, 1,800 m. s. m. (No. 5900). 
Conspicuous in the Thamnopteris group, and resembling a huge Vittaria, by 
the narrowness of the fronds, "which are so crowded that with the narrowest 
possible bases tliey form dense "nests. 
Asplenium scOLOPENnBioiDES J. Sm., has been previously collected near the 
foot of Mount Halcon by Merrill (Nos. 1810, 4075) and by McGregor (No. 239).

On ridges at 1,000 m. alt. (No. 5898), and in the mossy forest at 2,300 m. alt. 
( No. 5897 ) . 
Known from near the latter altitude on Mount Apo, Mindanao, and in northern 
* Luzon. 
India to Hawaii. 
Asplenium heterocarpum Wall. 
On cliffs in dense forests at 1,700 m. alt. (No. 589G). 
Not previously reported from the Philippines. 
India to Borneo and Formosa. 
+ 
Asplenium unilaterale Lam. 
On wet rocks at 1,400 m. alt. (No. 5895), 
Already known in the Pliilippines from Luzon and Mindanao.
