This is the piant to which Mr Brown aiiudes, at p. 138 of his Prodr., when speaking of
the genuine Cyathem, and of which he remarks, that it differs from them in having the
indusium arising from the middie (not the forking) of the vein: and this it is, together
with Cyathea sinuata, Hook, et Grev. Ic. Fii. t. 106, which Mr J . Smith has distinguished
by tiie name which we have here adopted. In the opinion of the iearned Presi, they,
togetiier with C. Mexicana, Schiecht., C. grandifolia, W ., C. marattioides, W ., C. spedosa,
W., and C. lavigaia, W., {C. Madagascarensis, Kauif.) constitute his first division of
Cyathea (§. N o to c a r p ia : .sort in medio dorso vence venulave) : but he expresses a doubt
if they ought not to be rejected from the reai Cyathea.
