248 FERNS OF. NORTH AMERICA.
Caucasus; also in Syria, Turkestan, Japan, Algiers, Madeira, and the
Azores. For a full discussion of the American stations, see the article
by Professor Paine above referred to, and compare with Pursh’s Journal.
D e s c r i p t io n . — The hart’s-tongue, though among the rarest
of American ferns, is a common plant in Europe. It has
a short root-stock, with adherent clustered stalks, which are
very chaffy, with narrow light-brown scales. The stalks are
only a few inches long, nearly terete, and contain a single fibro-
vascular bundle, which has three little bands of sclerenchyma
on its exterior surface. The texture of the living frond is
sub - coriaceous ; but it becomes more chartaceous in drying.
The undivided and tongue-like frond is usually undulate on
the margin, and may be either obtuse or acute at the apex.
Rarely the basal auricles are wanting. The sori are made up
of two Asplenioid sori facing each other on adjacent veinlets.
Moore describes sixty-six variations of form, some of them
exceedingly strange and abnormal. The genus, strictly limited,
contains three other species; but Hooker extends it so as to
include Azitigramme, Camptosorus, and Schaffneria.
The specimen drawn is smaller than the average, and was collected
at DeWitt, Onondaga County, New York, by Mr. L. M. Underwood.

L o m a r í a S p i c a n t Root-stock short and thick, very
chaffy ; fronds tufted, erect, smooth, sterile ones nearly sessile,
or short-stalked, sub-coriaceous, narrowly linear-lanceolate,
six to thirty inches long, one to three inches wide, tapering
from above the middle to both ends, pinnatifid to the rachis
into very numerous close-set oblong or oblong-linear often
upwardly curved obtuse or apiculate segments, the lower ones
gradually diminished to minute auricles ; fertile fronds taller
than the sterile, long-stalked, pinnate ; the pinnæ less crowded,
longer and much narrower than the sterile segments, sessile
by a suddenly dilated base ; involucres just within the margin ;
mature sporangia nearly covering the back of the pinnæ.
