The descriptions of both the type (flowering November 1918) and the 

 variety (flowering July 1919) are taken from living spécimens cultivated in 

 the Buitenzorg Gardens, the former, mentioned in Engler's monograph, 

 has been introduced from Ceram, the latter from an unknown iocality.

Monster., 58, fig. 24. 



Spécimens cultivated in the Buitenzorg Gardens, flowering November 

 1918, are distinguished as follows: Pétiole ± 40—80 cm. long, sheathed 

 nearly to the knee, the sheath narrowed towards the rounded apex; lamina 

 lanceolate-subovate, ± 50-75X10—30 cm., straight or somewhat falcate, 

 narrowed gradually towards the acute apex, the base somewhat unequal- 

 sided, obliquely rotundate-cuneate, shortiy decurrent upon the knee; prim- 

 ary veins about 15—25 on a side, oblique, impressed above, separated by 

 about 5-11 parailel scondary and tertiary ones. Peduncie ± 10 cm. long, 

 272 cm. diam. Spathe and spadix as in E. ceramense v. A.v. R. ioima 

 typica but the ovaries 4— 6-ovulate.

The description is taken from a spécimen doubtfuUy determined by 

 Lauterbach and mentioned by Engler (Nov. Guin., Vill, 249) as E am- 

 plissimum Engl. which differs from this principally by its sessile, much 

 thicker spadix.
