Van Alderwerelt van ROSENBURQH: Malayan Araceae 2. 165 



cylindraceo sensim subcymbiformis, 16 — 10 cm. longa, apice breviter acu- 

 minata et leviter recurvata, extus lactea ad pallide viridis, intus perpallida; 

 tubus 2'/2 cm. longus et 2'/2 cm. diam.; lamina explanata 8 cm. lata. Spadix 

 + 12'/2 cm. longus; inflorescentia feminea cylindracea, 1^/4 cm. longa, P/2 

 cm. crassa; ovaria perpallide viridia, 1-ovulata, in sicco prismatica, apice 

 truncata, 4 — 6-angulosa; stylus subnullus; stigma capitatum, pallide brun- 

 neum; inflorescentia mascula suboblongo-cylindracea, 3 cm. longa, média 

 parte 1^/4 cm. crassa, basi et apice paullo attenuata, r/2 cm. crassa, pallide 

 brunnea; appendix obovoidea, 8 cm. longa, 3 cm. crassa, basi attenuata, 

 apice semihemisphaerica, pallide flavida, caeruleo-viridi-afflata. 



The dimensions are taken from the field note; the dried material has 

 the dimensions of the inflorescences much smaller. 



A leaf of a probably young tuber, gathered at the same locality and 

 belonging probably to this species, is distinguished as follows: Pétiole 

 about 30 cm. long, slender, darker than the penduncle; lamina 3-partite ; 

 primary branches about 25 cm long, forked ; pinnae (leaflets) — 2 on 

 each side below the fork-branches, lanceolate, 7 — l7X3'/2 — 5'/2 cm., the 

 lowest sessile, the higher adnate with a cuneate base, the apex rather 

 suddenly long-subcaudate-acuminate; highest leaflets binate or subbinate.

The material is accompanied by 2 leaves which are so absolutely 

 différent that they cannot belong to one and the same species. The whole 

 flower imitâtes deceptively the dilated neck and head of an erected Cobra 

 or hooded snake (Naja tripudians).
