The genus Antrophyum—1, Synopsis of subgenera, 
and the American species 
RALPH CurTIss BENEDICT 
The genus Axtrophyum, as known at present, comprises more 
than thirty species of wide distribution in the tropics. Of this 
number, nine are confined to America, ranging from Mexico and 
Cuba on the north to Bolivia and southeastern Brazil on the south. 
The Old World species range from eastern Polynesia to Japan and 
China, south to New Guinea, the Mascarene Islands and Mada- 
gascar, and across Africa to the island of Fernando Po on the 
west coast. 
The genus was established in 1824 by Kaulfuss,* who named 
Six species, but recognized three more in a footnote. Three of the 
nine were American. The first species to be figured was the Old 
World A. reticulatum (Forster) Kaulfuss,t which may be consid- 
ered as the type of the genus. Only one of the nine, the Ameri- 
can A. danceolatum, was known to Linnaeus. 
The nine original species had been described under the Lin- 
naean genus, Hemionitis, with which, however, they have very 
little affinity. They are probably more closely related to Loxo- 
gramme Presl. Blume recognized this when he classified several 
Species properly belonging to the latter genus under A ntrophyum,t 
and Pres] placed one species of Antrophyum with Loxogramme.§ 
When the present work was commenced, it was intended to 
include the entire genus, but the material at hand was not suffi-
