Notes on AMERICAN FeRNS—XII 217 
all the divisions and segments oblique, distant; seg- 
ments mostly fertile, 3-7 mm. long, narrowly elliptical, 
pointed-elliptical, or oblanceolate (rarely linear), nar- 
rowly cuneate, their bases as broad as the greenish- 
marginate ultimate rachises; sori intramarginal, borne 
upon the swollen, nearly punctiform vein-tips, few- 
sporangiate, adjacent, confluent, not extending to the 
base of the segment, with a common proper indusium 
formed of the broadly reflexed. delicately membranous 
margin, the vein-tips evident without in the sinuses 
of shallow crenations at the base; indusia ample, often 
meeting at the middle of the segment, not decurrent 
upon the rachises, translucent, the margin delicately 
glandular-papillose or papillose-denticulate. Leaf tissue 
delicately membranous, sometimes minutely granular- 
crustaceous near the vein-tips above and on the lower 
part of the indusium, beneath beset with numerous, 
oblique or appressed, very minute glandular hairs, 
these usually wine-colored and appearing resinous. 
Type in the U. S. National Herbarium, No. 692694, 
collected on the steep moist slopes of Ramsey Canyon, 
Huachuca Mountains, southeastern Arizona, August 28, 
1912, by L. N. Goodding (No. 1327). Represented 
also by other specimens collected at the same place by 
Professor Goodding (No. 760) and by specimens col- 
lected in August, 1882, in Conservatory Canyon, of 
the same mountains, by Lemmon, all distributed as 
Pellaeca marginata, a South American species which 
barely reaches North America. While amply distinct 
from typical Mexican C. pyramidalis, the Arizona plant 
seems, nevertheless, to intergrade imperceptibly with 
larger but similarly decompound Mexican forms of 
more robust and upright habit through specimens 
collected in Chihuahua (Palmer 446; Pringle 1442), 
these necessitating its recognition as a subspecies merely.
