Caudex long, creeping, filiform, flexuose, rigid, here and

St ipe s short, filiform.
Frond from two to three inches tall, oblong in its outline,
bipinnatifid, with the pinnas erecto-patent,
alternate, the' segments long, linear, simple or
bifid, the margins spinuloso-dentate, furnished
with a nerve running down the middle, prominent
on each side, slender, brown, when dry fal-
cato-recurved. Rachis slender, winged, with a
membranous entire margin. The substance of
the frond is membranous, beautifully reticulated
with roundish meshes. The colour is brownish
green, brown when dry.
Involucra situated in the upper part of the axilla?,
nearly sessile, between ovate and roundish, compressed,
principally at the apex, of the same substance
as the frond, reticulated, two-valved, the
valves spinuloso-dentate at the extremity.
R eceptacle central,spongy, oblongo-clavate, included,
twice as short as the involucrum.
Capsules round, compressed, brown, fixed by their
centre, almost entirely covering the receptacle,
having their disk reticulated, the elastic ring
large, entire. 0
Seeds very minute, roundish.
B ill™ described it as a new species under the name of Ihjmcmplnjllum cupressiforme. '
