Of the three species mentioned hy Presl as belonging to this Genus Cyclodium, I am
only, with certainty, acquainted with one, the C. confertum, which has a very peculiar
aspect, and the fertile fronds dissimilar not only as to size and form, but also as to venation
the venation, however, is considerably different from that represented by Presl,
Tent. Pterid. tab. U .f . 20, 21.

Sori globosi. Indusium orbiculatum, p e lta tum .— Frondes fasciculatoe, pinnatæ,
pin n is petiolatis, acuminatis, argute serrulatis, infimis lobatis. Venæ internæ, tenues,
in macidas irregulares et inoequales anastomosantes. Maculæ costales hexagonoideæ,
angulis superioribus uno-tribus venuUferoe. Venulæ rectoe, liberoe, acutoe, medio

Cyrtomium caryotideum. Pre si.— ( T a b . X L IX . C .)—Aspidium caryotideiim.

The only two known species of this Genus are of Indian origin, tropical or subtropical,
and h.ave a peculiar habit ; but it must he confessed that their venation approaches very
nearly to that of Cyclodium.
