Hab. Brazil, Venezuela, Peru, Mexico, Guatemala, Salvin & Godman, n. 358 ? and
14 ?.—Martius has well represented in his plate the copious, glossy, ferruginous scales
which clothe the nascent frond (t. 54, f. 1), of which the author takes no notice in his
diagnosis. In the absence of these on our copious specimens, named and unnamed, I could
not refer to any essential distinguishing character. Among our thus authenticated speci-
mens are Fendler’s, n. 54, and Sellow, from Ilevh. Reg. Bras.—Such good figures as those
of Martius must not be thought light of ; but even they require to be accompanied by
good diagnoses, and. unless they are specially well-marked species, with some notice
also of the affinities.

quite different.

Hab, Mexico.—I find this species to have the sorus sometimes on the back of a single
vein, and sometimes on the fork of a vein, so that there is no reason to separate this
species, as some authors have done, from the great mass of Cyathece which have bi-tripin-
nate fronds, with which, too, it is naturally allied. Presl. gives a figure of the venation
(Tent. Pterid. t. 1. f. 8 ), but only represents the simple form, with dorsal sori.

aud veins, lowest inferior one adnato-decurrent ; sori covering the whole underside
of the lobe ; invol.. almost globose, pale-brown, opaque, with a dark mam-
millate apex, a t length bursting with a small aperture a t the top.—H k . Sp. p . 21.
