Van Alderwerelt van Rosenburgh: Malayan Araceae 2. 173 



Var. purpurasccns [H. piirpurascens, SCHOTT) : Like the type but the 

 sheath of the pétiole reddish, the lamina above reddish or dark-green. 

 — Hallier's No. 3223 from Bornéo, determined by Engler as var. pur- 

 piirascens, is a species near H. humiiis Hk. F. 



Homalomena Kingii, Hk. F.. Flor. Brit. Ind., VI, 535; EnGL., Pflzrch, 

 LV (IV, 23 Da). Arac.-Philod -Homal.-Schism., 41, fig. 21. 



According to the diagnosis and figure given by Engler, this species 

 has an oblong-ovate lamina about twice to thrice as long as broad, with 

 a rotundate-truncate base. Raap's No. 117 from Botoe IsLand, determined 

 and mentioned by ENGLER, however, has a very broadly ovate lamina at 

 best 1 '/2 X 3S 'ong ^s broad, with a slightly cordate-emarginate base, narrow- 

 ed gradually towards the apex. Spécimens from Sumatra (BiiNNEMEljER 

 Nos. 3239, 3254) are distinguished in having the lamina as broad as in the 

 Batoe plant but the base is not emarginate but very broadly truncate- 

 cuneate and abruptly, shortly cuneate.

WiNKLER's No. 2277 from Bornéo is unknown to me. — Two spéc- 

 imens from an unknown habitat, cultivated in the Buitenzorg Gardens, 

 determined by ENGLER several years ago, differ from the original diagnosis 

 of the species. They are distinguished as follows: Pétiole shorter or some- 

 times somewhat longer than the lamina, 3'/2-12'/2 cm. long, green with 

 a reddish sheen, sheathing about 1/3 — '/2 '^s length, the sheath red or 

 broadly red-margined; lamina elongate-ovate or triangular with broadly 

 rounded basai corners, 7'/2— 12'/2 X 2'/2— 7'/2 cm., red-margined, above 

 moderately dark-green, beneath green intermixed with dirty-red, the base 

 rounded or truncate, whether or not more or less cordate-emarginate; prim- 

 ary veins 3 — 6 on a side, ascending, or the basai ones horizontal or 

 slightly deflexed in the leaves wilh a truncate or emarginate base. Peduncle 

 1— 3'/2 cm. long, green. Spathe l'/2— 2'/2 cm. long, ^U—^U cm. diam., 

 green, becoming gradually reddish towards the finely long-cuspidate-acum- 

 inate apex. Ovaries green, broadly conoid-ovoid, with the stigma as broad 

 as the apex of the ovary ; staminodes clavate from a slender base, white ; mas- 

 culine flowers nearly white, 2 — 4-androus, the 3-androus ones resembling 

 Engler's fig. 25 D. — Thèse différences may be due to the conditions in 

 which the cultivated plants are placed. — Another spécimen, from Bornéo, 

 approaches the habit described by ENGLER, 



Var. subconcolor: Foliorum lamina utrinque viridis sed subtus quam 

 supra pallidior, rubro-cincta; pedunculus apicem versus pallide viridis, ce- 

 terum roseus; spatha pallide viridis. — Sumatra, (D^//, JAHERI ; cultivated 

 in the Buitenzorg Gardens, flowering July 1920).
