Spécimens cultivated in the Buitenzorg Gardens, determined by Engler, 

 liaving flowered March 1921, are distinguished as foUows: Leaves with the 

 pétiole 2—4 cm. long, the anterior side more or less canaliculate between 

 the sheath and the lamina, the sheath IV2— 3 cm. long, finally scariose and 

 more or less dilacerated; lamina elliptical-oblong or ovate, to 15 X 7'/2 cm., 

 the upper surface dark-green, opaque-velutinous, spotted, the spots very 

 irregular and irregularly scattered, pale-yellowish-green, hère and there pale- 

 greyish-green, especially near the costa, the base rotundate or rotundate- 

 cuneate, occasioiially slightly emarginate, the apex acuminate, shortly api-

 grooved in the lower part, beneath prominent, semiterete ; primary veins 

 impressed above, prominent beneath, stouter than the secondary ones. Pe- 

 duncle 2'/2— 3cni. long, pale-green. Spathe broadly oblong or obovoid,

 rescence, the higher nearly resembling the fertile ones; fertile stamens 

 dirty-white or ivory-white. 



The young plants hâve the leaves with the spots not irregularly scat-
