?essile, oblong, ronnded at the outer end, the inner
truncate, inferior margin obliquely cut away, the
rest crenate-dentate, 4 to 6 lines long, 2 to 3 lines
wide, the inferior gradually dwindling to mere
•uridM, those above passing as gradually into the
lobate-dentate obtuse apex of the fronds ; rachis green
channelled ; veins few, pinnate, simple or forked ;
sori oblique, short, medial, 1 to 1£ lines long ; invo-
lucre narrow, silvery, partly concealed by the elevated
sporangia at maturity. Barbados, West Indies,
«growing on the tide« and in crevices of dripping
calcareous rocks in caves in the interior of the
island ; a species intermediate between the European
A. viride and the Antillian A, dentatnm, from the
latter of which it is well distinguished by the barren
ind fèrtile fronds having the same habit, the pinose
being twice to thrice as nnmerous and contiguous,
their different shape, and descent and dwindling to
the base of the diminished stipite*. The small
densely tufted fronds, leaved to the base, make it a
very pretty small pot, pan, or rock plant. 6, S.
