Ocroser 30, 1908] PTERIDOPHYTES OF THE lioRN or NEGROS 
LEPTOCHILUS Kaulf. 
Leptochilus heterochilus (Presl) C. Chr. var. Foxworthyi 
Christ in Philip. Journ. Sci. 2 C (1907) 160. 
On mossy rocks near Bonyao river, alt. 850 m., No. 10041. 
Luzon (this variety). 
Leptochilus heteroclitus (Presl) C. Chr. 
On rocks near Bonyao river, alt. 750 m., No. 9705. “‘Tagu- 
buyoe.’’ 
Throughout the Philippines. 
Subtropical Asia to Melanesia. 
A part of this collection is the same as my No. 1543 from 
Zamboanga, determined by Christ as L. diversifolius Bl. I think 
Mr. Elmer is right in collecting them as the same plant. 
He observes, ‘‘An exceedingly variable species." 
LOMAGRAMMA J. Sm. 
Lomagramma pteroides J. Sm. var. subcoriacea Copel. 
In deeply shaded ravines, alt. 900 m., No. 10175. 
Rhizome growing from soil, much branched, scandent; 
the fronds heavy, coriaceous, the fertile usually terminal, not 
common. 
This variety has been found in Mindanao and Paragua. 
Lomagramma pteroides J. Sm. var. negrosensis Copel. 
var. nova. i 
Pinnis sterilibus cuneato-truncatis, late lanceolatis, quam 
typo brevioribus, herbaceis, grabrescentibus, fertilibus plerumque 
sessilibus, vix basin versus dilatatis. 
Creeping over large boulders and ledges of a damp gorge, 
alt. 600 m., No. 9678. Local name, ''Locdo-na-balagon."'

In the plants from Luzon and Mindoro, which I re- 
gard as typical L. pteroides, the sterile pinnae are longer and 
narrowly lanceolate, the fertile for the most part stipitate 
and dilated at the base. The variety negrosensis differs from 
subcoriacea in thinner texture, permanently clear green color, 
and comparative nakedness, and from the type and var. sub- 
coriacea in the non-cordate base of the less acuminate and 
less falcate sterile pinnae. Both of these varieties will prob- 
ably prove to be good species, and would be so described, but 
that I have still other forms of questionable status.
