This plant appears to be the next species which was definitely 

 made known. In the Kew Collection, in addition to the earlier 

 plants of Wallich, there are abundant recent specimens. The 

 plant is a coarse species with the sterile lamina ranging up to 30 

 cm. broad and 25 cm. long; the petiole of the sterile lamina is 

 usually short (4-6 cm.); the stem is elongate, often up to 3 dm. 

 The plant is ternate but the two lower divisions are alternate, vary- 

 ing as much as 1-2 cm. in their origin ; the texture is thin, the 

 veins being clearly visible and consist in each segment of a main 

 vein pinnately branched and a second smaller supplementary vein 

 rising below the mid vein. This feature is very characteristic, ap-

vein. The segments are set at an angle of about 45 ° to the 

 rachis and the lower are often lobed on one or both sides. Very 

 large specimens rarely show a second smaller supplementary vein. 



The species is represented by fifteen sheets in the Kew Her- 

 barium, besides a specimen from Samoa gummed on a sheet with 

 B. Japonicum mentioned below. The distribution includes Nepal, 

 Nilgherries, Sikkim, Ceylon, Birmah, Society Islands, Samoa. A 

 single specimen from Java has more acuminate segments, lacks the 

 supplementary vein and deserves further study. 



B. subcamosum differs mainly in its smaller size, shorter peti- 

 ole to the sterile lamina, and more simple panicle ; it can hardly 

 be maintained as distinct.
