D e s c e Root a small disc. Eronds either solitary or somewhat tufted, from four
inches to a foot in length, commonly compressed, rarely cylindi-ical or nearly
so varying in breadth from the thickness of ,a bristle to nearly a line, fm--
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 lower-most of which are the longest, the upper being
U d u a lly shorter as they approach the apex : thus giving to the frond an
ovate outline. Loiver branches simüar to the stem in ah respects, fmnished
with a second, third, or even fom-th 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 ciliæ, aline m length; on the older
stems only are they partially obliterated. The capsules, which are invanably
