H a b . — On the walls of a limestone cave at Schurlock’s Spring,
Jackson County, Florida, Dr. C h a pm an. Also near Ocala, Florida, collected
by Mr. W. H . S h o c k l e y , and by Captain J ohn D o n n e l l S m it h ,
who found it “ growing in tufts at the bottom of pocket-like holes in
cavernous liirie rock, the fronds spreading flat around the orifice.” Also
in the West Indies, Mexico, and parts of South America.
D e s c r i p t i o n : — This is the most delicate and finely divided
of all our Spleenworts, and need not ’ be confounded
with any other native species.
The lower pinnules of each pinna are more or less lobed,
being usually deft into from three to five little lobes. A
few of the next pinnules are often two to three-lobed, and
the rest are mostly entire. The solitary veins and sori show
a close approach to the section Darea of the genus Asplenmm.
A . cicutarium, recently collected in Sumpter County,
Florida, by Mr. Shockley, comes nearest to it, but has broader
and, when fully developed, much larger and coarser fronds.
A . monteverdense, of Hooker, is scarcely distinguishable from
our plant, and, indeed, Wright’s 1092 seems to be precisely
A . myriophyllum, and was collected also “ at the entrance of
caverns.” A . rhizophyllum is a larger plant, and has usually
a prolonged radicant apex.
The specimen figured is among the largest of those collected by
Dr. C h a pm an .
