Van AlderweRELT van RosenburgH: Malayan Araceae 2. 223 



as is drawn in the figure. —No. 1 55 is still undeterminable because of the absence 

 of complète, floriferous materiai; the leaves, however, agrée exactly with those 

 of No 116 {Bornéo, NIEUWENHUIS No. 1748, cultivated erroneously under 

 the name of Sch. iongicuspis Enql.), which is a form of Sch. Nieuwenhuisii 

 Engl , differing from the typicai form in having the leaves somewhat narrower 

 and the féminine inflorescence provided with less numerous staminodes. 



According to the information given above, the description of Sch. 

 emarginata Engl. should be modified as follows: 



Caudex very short, copiously rooting. Leaves with the pétiole T'/a — 15 

 cm long or even longer, sheathing half its length or more, green, the upper 

 part canaliculate on the anterior side, narrowly cristate-2-marginate, the 

 crests passing into the lowest veins; lamina herbaceous, elongate-ovate- 

 lanceolate, 10 — 15X272 — 5 cm., the upper surface dark-green, grey-green at 

 the apex, provided on each side of the green cdsta with a row of mostly 

 confluent, irregular, pale-grey- green spots which are placed closely to the 

 Costa or approaching the same, for the rest copiously pale-punctate- 

 under surface pale-green; apex slightly falcate, acuminate, shortly apiculate; 

 base rounded in the smaller leaves, more or less cordate-emarginate in the 

 larger leaves, the lobes at best '/2Xl'/2 cm., broadly rounded, separated 

 by a rectangular or very obtuse sinus; primary veins 7 — 11 on a side, the 

 basai ones subhorizontal or somewhat radiating, the costal ones obliquely 

 ascending, upcurved, decurrent at the base; secundary and tertiary veins 

 finer than the primary ones. Peduncle 3 — 3^2 cm. long, pale-green. Spathe 

 about4— 5cm, long; tube obconoid-obovate, l'/a— 2 cm. long, '/2— 1 cm.diam.; 

 lamina closed conoid-fusiform, open ovate, 2'/2 — 3Xr/2 cm., yellowish, 

 acuminate. Spadix 2'/2-3'/2 cm. long; féminine inflorescence conoid, + 1 — 

 IV2 cm. long, 3-5 mm, thick, somewhat less than the lower half connate 

 with the spathe ; ovaries conoid-ovate, pale-green, the apex shortly styliform- 

 attenuate; stigma sessile, discoid, round, pale-green; staminodes among the 

 pistils few, mostly shorter or sometimes hardly longer than thèse, scattered, 

 capitate or shortly clavate, white, relatively long-stalked ; masculine inflor- 

 escence clavate, l'/g— 2 cm. long, '/2— ^^4 cm. thick, separated from the 

 féminine by a short interstice provided with several, short-oblong, neuter 

 organs; fertile lower portion obconoid. 1 — 1 '/4 cm. long, dirty-white; 

 stérile apical portion semioblong, \2— ^4 cm. long, not or hardly thicker 

 than the fertile portion, ivory-white, the apex rounded; thecae cupuliform, 

 shorter than the filament, truncate at the apex; staminodes not or hardly 

 longer than the stamens, subprismatical or elongate-clavate, the apex rotund- 

 ate-truncate or rounded, obtusely angular or roundish. minutely foveolate. 



The description is taken partly from living spécimens, partly from dried and 

 from alcohol materiai. The flower, preserved in alcohol, has the stalks of the 

 lower staminodes, the neuter organs and the higher staminodes provided with 

 brownish points or short, longitudinal stripes wanting in the living flower.
