Descr. Root a small disc. Fronds either solitary or somewhat tufted, from four 
inches to a foot in length, commonly compressed, rarely cylindrical or nearly 
so, varying in breadth from the thickness of a bristle to nearly a line, fur- 
nished with an undivided stem which is set throughout its whole length, 
except for a short distance above the base with alternate, closely placed, 
patent branches, the lowermost of which are the longest, the upper being 
gradually shorter as they approach the apex: thus giving to the frond an 
ovate outline. Lower branches similar to the stem in all respects, furnished 
with a second, third, or even fourth series of lesser branchlets; upper 
branches less divided. Every part of the frond is pectinated, at distances 
of a line or less, with subulate, alternate ciliz, a line in length; on the older 
stems only are they partially obliterated. The capsules, which are invariably
