Communicated by the Honourable the East India Company as a native of the East Indies ; but 

 of which particular district of the Indian possessions is not stated : — probably Nepaul. It differs 

 from every species hitherto described, in many points ; yet in the decidedly cuneate form of the 

 foliola, it approaches the tribe with the membranaceous leaflets, to which A. Capillis Veneris 

 belongs. Here, however, the foliage is remarkably rigid and coriaceous ; and on looking at the 

 upper side of a frond, the stipes, rachis, and pedicels will be found to be rough with short close- 

 set harsh brown hairs, whilst the rest of the plant is quite glabrous.
