 having the lamina biackish when dry, wilh the basai 

 lobes much shorter, V?— '/e ^he length of the antical

Spécimens gathered in Batavia by C. A. BACKERand others cultivated 

 in K. Heyne's garden in Biiitenzorg are distinguished in having the pét- 

 iole to about 75 cm. long, dark-purple, the lamina to 47'/2X35 cm., the 

 spathe to S'/,— 9 cm. long, purple, the spadix to 9 — 10 cm. long, on a 

 stalk about '/s cm. long, the ovaries oblong-ellipsoidal, yellow-green with 

 a purple apex, the staminodes obconoid-clavate, ivory-white, long-stalked, 

 the masculine inflorescence about twice as long as the féminine, '/2 cm. 

 thick. — A spécimen gathered in 7y7Z?£'Z?^r by W. F. WiNCKEL at an altitude 

 of 1000 m. differs in having the différent dimensions smaller. 



A plant gathered in Sumatra (Dell, Slbolanglt, J. A. LôRZiNG No. 

 5324, 10 October 1917), which may be a form of this species, is disting- 

 uished in having the caudex to 1 m. high, the leaves with the lamina 

 deeply cordate at the base, with the basai lobes nearly half as long as 

 the antical lobe, the spathe smaller than in the type, pale-red, the spadix 

 about 5-6 cm. long, with the masculine inflorescence about l'/2Xas 

 long as the féminine.— Ail the portions of this spécimen are said to be 

 awfuliy stinking; the young leaves and the cataphylla are bright-pale-red. 



Homalomcna alba, HASSK., Catal. Bog , 57; EnGL., Pflzrch, LV (IV, 

 23 Da), Arac.-Philod.-Homal.-Schism., 63. 



A spécimen gathered bij C. A. Backer near Batavia is distinguished 

 in having the lamina large, 60X45 cm., the spathe 9— 9'/2 cm. long, 

 greenish-white, the spadix 9'/2— 10 cm. long, on a stalk + 5 mm. long, 

 the féminine inflorescence cylindrical, 2^/4 cm. long, the ovaries more or 

 less oval, yellow-white, the staminodes obconical-clavate, very thick, long- 

 stalked, the masculine inflorescence about twice as long as the féminine.— 

 This is perhaps hardly more than a form or variety of the preceding. In 

 dried state BACKER's spécimens of both species are not distinguishable 

 rfom each other.
