A plant consisting of a single leaf and a single flower, coUected in 

 Berhaia Island (Sumatra's Eastcoast, in forest, ait. + 50 m., J. A. 

 LôRZlNG No. 6Q88, 2 November 1Q19), which may be a form of this 

 species, differs from the type of this in having the fertile and stérile por- 

 tions of the masculine inflorescence resupinate, i. e. the lower part stérile, 

 obconical, less than half as long and the upper part fertile, elongate-ellip- 

 soidal, blunt, more than half as long as the whole masculine inflorescence 

 (forma resiipinata). — The mater ial is too incomplète for the detailed de- 

 scription of an eventually new species.
