Plants often very robust. Leaf-blade somewhat oblique, typically broadly 

 elliptic, uncommonly varying' to elliptic-rotund or narrowly elliptic, 35-50 (-85) 

 cm long and (11-) 14-24 (-30) cm wide, widest just at the middle, rounded 

 toward the apex and ending in an acuminate-cuspidate point 2-5 cm long, the 

 base mostly obtuse or sometimes acute ; petiole subequaling or a little longer than 

 the blade, 30-45 (-63) cm long, prominently alate to the base of the geniculum or 

 less, the wing early deteriorating; geniculum 1.8-2.5 (-5) cm long. Peduncle 

 1.5-2 times as long as the blade, (35-) 50-75 (-90) cm long ; spathe reflexed, lance- 

 olate or oblong-lanceolate to elliptic- ovate, rarely ovate-rotund, 14-24 (-35) cm 

 long and (3-) 5.5-8 (-14) cm wide, long-attenuate or acuminate, the base obtuse 

 to subrotund or cordate ( !), sometimes decurrent on the peduncle 0.4-2 (-4) cm; 

 spadix 5-9 (-16) cm long, on a stipe 0.3-3(-5) cm long; perianth fleshy, formed 

 into a round or 4-6-sided truncate cup nearly concealing the pistil and 5 or 6 

 stamens within; pistil cylindric-obpyramidal, the apex subtruncate varying to 

 conic or occasionally attenuate or dome-shaped in age ; ovary 3-locular, the ovules 

 superposed, varying from 7-2 in each of the 3 locules, totaling 21-10 (-6) ovules 

 per ovary; fruiting spadix smooth, the fruit cylindric and rostrate, or the apex 

 truncate and crowned by the persistent stigma ; seeds nearly as many as the 

 ovules, oblique-reniform or ovoid to comma- or horseshoe-shaped in profile, tan- 

 colored, the surface quite smooth or sparsely foveolate. 



Type collection: H. Cuming s.n., "Philippines" (holotype BM). That collector 

 visited Pacific islands and the East Indies between 1836 and 1839. It is unknown 

 from which island of the Philippines this specimen came.
