mg out from the short thick nerve of the calyx. Perigonial
scales resembling bladders, inclosing several roundish anthers,
attached to the circumambient nerve. The pubescence
of the frond consists of very short hairs inserted between
the cellules.
We think it essentially distinct from J.furcata, because
in that species we observe the frond to be truly dichotomous,
or repeatedly forked; the branches fewer, more
distant, with the margins usually recurved; the cellules
much larger, and the beautiful reticulation which they
form regularly hexagonal, and for the most part destitute
of pubescence, except at the margin and on the rib
beneath; the marginal cilia (sometimes altogether wanting,)
consist of long recurved hairs connected in divaricating
pairs, and very different from those of J . pubescens.
