 yellow-green with a dark-purple tip; style slender, cylindrical, somewhat 

 shorter than the ovary, dark-purple; stigma capitate, slightly lobed, the 

 lobules separated by shallow grooves; masculine inflorescence commonly 

 somewhat shorter, sometimes somewhat longer than the féminine, elongate-

 slightly but distinctly contracted above the base, for the rest elongate- 

 conical, ± 10 — 40 cm. long, 1—7 cm diam. in the thickest portion, gradually 

 attenuated towards the bluntish apex, when dry finely longitudinally rumpled,

According to spécimens occurring in the Buitenzorg Herbarium and 

 Backer's manuscript notes Engler's diagnosis should be completed as 

 follows: Pétiole 20—100 cm. long, like the peduncle very variably coloured 

 and spotted, often green- or brown-green- and paler-mottled ; lamina 12— 100 

 cm diam ; ultiinate segments oblong or lanceolate, more or less long- 

 acuminate. Peduncle smooth or roughish, 12 - 100 cm. long. Spathe erected, 

 campanulate-convolute at the base, when explanated elongate-triangular- 

 ovate, as a rule 5 times as long as broad, 9— 22 cm long, acute-acuminate, 

 inside greenish-white, the base yellow, verrucose, outside pale, green- or 

 purple-bloomy or quite purple, sometimes red-margined, often provided 

 with some pale points or spots. Spadix with the féminine inflorescence 

 cylindric, l'/4— 4 cm long; ovaries green; stigma capitate, more or less 

 distinctly lobed; masculine inflorescence IV4-2 X as long as the féminine, 

 cylidric or slightly obconoid, 2—6 cm. long; appendix proportionally long 

 and slender, elongate-conoid, 10—40 cm. long, l-S'/a cm. diam, terete or 

 somewhat laterally compressed, smooth or somewhat rugose or verrucose, 

 pale-yellow to dirty-purple. 



In open field, jungle and secundary forest; ait. 1—700 m.; flowering 

 whole the year over but mostly June to December.
