This species o f Aepteuiusn, lo n g ago figured b y Plumier, bears iu many respects a considerable
resemblattee to A .m a rm u m ; but its fronds are broader and shorter, the pinnæ have qnite a diffe-
rent texture, b e in g remarkably tl.in , membranaceons and pellncid, and instead o f r egn k r scrraturcs
th e margtn ts slnnato-dentate, the te e th form in g so many irregular small .angles. I t appears, both
from .ts Itab.t and from what Plumier says o f its place o f growth, to be almost an .aquatic fern
" I t IS found," observes that author. " at the sources o f b rooks, npon m o ist and m o ssy rocks I
have even seen i , in the water itse lf o f a spring upon the summit o f the Calebasse mountain in
Martinique.”
