The plants occurring in the Buitenzorg Herbarium, referrible to this 

 species, do not agrée entirely with BuCHET's diagnosis and are distinguished 

 as follows: 



Leaves with the pétiole to 40 cm. long,- the sheath rather broadly 

 rounded at the apex, the lamina with the segments sessile or more or less 

 distinctly petiolulate, elliptical-oblong to -lanceolate, to 26X1 ^ cm., the terminal 

 (medial) one equal-sided, cuneate at the base, the latéral ones unequal-sided, 

 broadest on the outer (lower) side, with the inner base cuneate, the outer 

 base broadly rotundate-cuneate to rotundate. Spadix 6— 10 cm, long. Maie 

 spadix with the inflorescence to 3 cm. long, loosely floriferous, the flowers 

 2— 3-androus; appendix subuliform, hardly exceeding the tube of the 

 spathe in the smaller, but distinctly so in the larger spécimens, the lower
