DESCRIPTIONS OF THE SPECIES 109 
long, one to two feet broad, with a stipe one foot long, 
which is densely set with reflexed, lanceolate, pointed, dark 
scales toward the base, while the upper part, as well as the 
rather rigid rachis and secondary rachises, are set with 
spreading or reflexed hair-like dark scales, which are smaller 
upward. Lowest pinnae largest, and with the lower side 
larger than the upper ; other pinnae almost equal sided, 
tapering slowly from a base three inches broad. Pinnules 
ovate-lanceolate, obtuse, cut to the mid-rib below into oblique, 
oblong, obtuse segments, which are entire, or the lower ones 
pinnately blunt lobed. Sori near the veins in the upper half 
of pinnules rather large. Indusium small, not hairy, per- 
sistent. Veins pinnate with few forked veinlets. Buchanan 
says — “While growing, the fronds are covered with long hairs, 
strikingly transparent in the sunlight, but quickly disappearing 
in the process of drying.” In Holland’s specimen they show 
well even on the dried frond.
