Bulletin Jard. Bot. Buitenzorq, Vol. IV. LivR. 1, 



has the leaves agreeing exactly with EnGLLR's incomplète diagnosis except 

 in some of the dimensions, which may be due to différent circumstances. 

 The plant is distinguished as follows: Caudex to 15—20 m. high climbing, 

 with the internodes + 1 cm. thick. Leaves with the pétiole to 30 -40 cm. long, 

 canaliculate and sheathing quite to the knee, dorsaliy densely but very 

 minutely puncticulate, when young perhaps minutely puberulous; sheath 

 membranaceous, soon dilacerated, caducous; knee to ±2 cm. long; lamina 

 flaccid-coriaceous, oblong, to 25— 45 X 12'/2— 20 cm., above dark-green, 

 beneath pale-green, more or less (not very) unequal-sided, the base oblique, 

 rounded or rotundate-cuneate, the apex more or less suddenly and very 

 shortly, acutely acuminate; costa above fiât or somewhat depressed, beneath 

 very prominent, densely, minutely, deciduously puberulous (when dry not 

 thinly tomentose among the hairs '), of the adult plant flanked on each side 

 with one to several suborbicular, oblong or deltoid-oblong holes V2~3 cm. 

 long, placed between the primary veins ; primary veins 20 — 30 on a side, 

 spreading, upcurved towards the apex, prominent beneath, separated by 

 + 3 finer secondary veins united by still finer transversal veinlets. Peduncle 



7'/2 — 10 cm. long. Spathe thick, cylindrical, to + 

 15 cm. long, IV2— 2 cm. diam., when young pale-green, 

 afterwards yellowish, acute. Spadix very short-stalked, 

 cylindrical, floriferous 7'/2— 10 cm. long, pale-yellow, 

 fructiferous to I21/2 cm. long, 2'/2 cm. thick, bluntly round- 

 ed at the apex; ovaries prismatical, the base laterally com- 

 pressed, the upper '/a thickened, semiglobose-pyramidal, 

 6-angular, the apex rather rounded, attenuated suddenly 

 into a very short, thick style (fig. z) ; ovules numerous, 

 arranged in 2 rows along 2 opposite pariétal placentae; 

 stigma discoid, round, somewhat broader than the style, 

 flat, with a small central dépression. 



A non-flowering plant, up till now cultivated in the 

 Buitenzorg Gardens under the name of E. foraminiferuni Engl., probably 

 determined by Enqler, has the leaves agreeing exactly with LôRZlNG'S 

 Sumatran plant. 



Fig z. 



Raphidophora celatocaulis, V. A. V. R., this Bull., !^ 382. 



Lamina of the fully developed plant with the segments to 15 or more 

 on a side. Peduncle 17'/2 — 20 cm. long. Spathe thick-fleshy, when young 

 cylindrical, convolute, acuminate, green, of the flowering spadix quite open, 

 very pale and soon becoming greyish on the inner side, bright-yellow on 

 the outer side, soon falling. Spadix 12'/2 — 20 cm. long, 2— 2'/2 cm. thick, 

 pale- or dirty-grey-yellow, soon becoming green ; stigma black or black- 

 brown, longitudinally grooved.
