The Synopsis gives e A. caryoUdmm, Wall, but adds — " It is impossible to 

 separate our two varieties satisfactorily." Clarke gives A. caryotideum as a 

 synonym. Beddome does not give A, falcatum as an Indian plant, and says 

 it differs only slightly from B. caryotideum. The N.-W. Indian plant seems to 

 be the latter, which is very commonly cultivated in Great Britain. It loves 

 water and shade — in the Himalaya. Mr. Clarke's No. 17656, from Assam, 

 Khasi Hills, has very long, narrow, falcate and toothed pinnse, 7 ins. x f in. : 

 one frond has pinnae 5 in. long, by only 1 in. broad.
