A. lasiopteris.

rather chaffy and villose.
Hab. Japan, China, Formosa, Himalayas.—The Samoan and Fijian 7). congruum.
Brack, t. 18, comes very near to this. In a specimen from Mr. Powell, the substance is
very thin, the rachis naked, the lobes J in. deep, j in. hr., veinlets 6-6 on each side, most
of them again forked ; and a similar plant grows in the Sandwich Islands.

Hab. Canton, Java, and the Neilgberriea, well figured by Beddome, t. 160.—This is
tbe 7). decussatum of English gardens ; but our original specimen from Wallich is A. japo-
nicum. I t comes near the two preceding, and the three are well marked by the character
of the rhizome.
