keeled, of the same colour as the lamina ; veins when dry very distinct on 

 both sides, fine but prominent, the primary and secondary ones nearly equal, 

 the former, however, occasionally (few to several on one side or on both 

 sides of the costa) beneath thickened gradually from the apex towards the 

 base. Spadix at length about 15 cm. long by 2 cm. thick, with the highest 

 pistils stérile ; style very short ; stigma oblong, of the higher fertile pistils 

 rather rounded. 

 Amboina. 



Scindapsus marantifolius, MlQ. ; V. A. V. R., this Bull., 1^, 7920,388. 



The javanese plants referrible to this species are distinguished from 

 the Amboinese plant mentioned above in having the pétiole with the 

 margin of the sheath scariose, dilacerate and deciduous, the lamina coriaceous, 

 somewhat thicker, oblong-ovate, about 2'/2 — 3 X as long as broad (to 30 

 — 45X10— •'^72 cm.), broadest commonly in the lower half, occasion- 

 ally at the middle, the base occasionally obliquely and broadly rotundate- 

 cuneate, the costa beneath when dry rather rounded (semiterete), the veins 

 somewhat less distinct and less prominent but the occasionally thickened 

 primary ones much more thickened in the lower half, the spadix at length 

 about 10 cm. long, the styles varying from very short to distinctly conically 

 elongated (see Schott, Gen. Aroid., tab. 80), which may be due to 

 différent circumstances independent from the species, the stigma round or 

 occasionally suboblong. 



The living plant has the spadix yellow. 



Java. 



Scindapsus javanicus, V. A. V. R., this Bull., P, 1920, 389. 



This species, which is surely very neary related tô the preceding 

 and may perhaps be considered as a narrow-leaved form of it, is distin- 

 guished from it in having the lamina lanceolate, about 4 X ^s long as broad 

 (25 — 42X6—11 cm), broadest at or a little below the middle, the base 

 as a ruie obliquely rotundate-cuneate, occasionally obliquely rounded ;extraor- 

 dinarily thickened primary veins and elongated styles wanting (in the material 

 in hand). 



The living plant has the spathe yellow, soon desiccate and becoming 

 black, caducous, the spadix yellow or pale-orange. 



Scindapsus alpinus, V. A. V. R.

 + 35—40 cm. longus, canaliculatus, usque ad geniculum ± l'/j cm. longum

 crassiuscula, elongato-ovato-lanceolata, plus minusve falcato-curvata, + 35 —
