848 LEAFLETS OF PHILIPPINE BoTANY [Vor. III, Arr. 45 
The species is found on high mountains throughout the 
Philippines and in Celebes. 
Hymenolepis spicata (L. f.) Presl. 
No. 11448. The common, small form with narrowly 
linear fertile apex. The veins are conspicuous and purplish. 
Mt. Apo, alt. 2050 m. “‘Kalili.”? This general form is found 
throughout the Philippines and at various altitudes. 
No. 11482. A very large form, the fronds up to 60 
em. long, with broad fertile apex. Mt. Apo, alt. 1800 m. 
"Barawit. This form was previously collected here by; 
Williams and myself. It is evidently not rare in Mindanao 
and what seems to be the same form occurs in the high 
mountains of northern Luzon. It suggests a hybrid of 
H. spicata and H. platyrhynchos. 
CHRISTIOPTERIS Copel. 
Christiopteris Sagitta (Christ) Copel. 
Epiphytic in dense woods along Mararag creek, alt. 1600 
m., No. 11568. ''Cacain-cain." This material collected in 
August is all sterile. I searched in vain for fertile fronds 
in the same locality in October, 1904. This is the form 
which Christ (Bull. Herb. Boiss. 1906, p. 990) suggests sepa- 
rating as a distinct species from C. Sagitta; but as it has 
never been found fertile, and is not really distinct from 
juvenile forms of that fern, I prefer to regard it as identical. 
LECANOPTERIS Bime. 
Lecanopteris pumila Bl. 
In moist woods above Todaya, alt. 1200 m., No. 10491. 
"Libagod." Rootstalk glaucous green, and forming a mass 
similar to a relief map of a mountainous section. 
Van Alderwerelt treats L. pumila as a variety of L. car- 
nosa; if he is right in this, at least one of the Philippine
