A spécimen occurring in the Buitenzorg Gardens, formerly cultivated 

 under tiie name of Sch. calyptrata Z. & M. var. maeiiLata forma albido- 

 maciilata, is distinguislied from the diagnosis given by Enqler and Krause 

 in having the leaves with the pétiole about as long as the lamina, the 

 lamina 2— 2'/2 X as long as broad, with the spots of the upper surface 

 pale-green of pale-yellow-green, with the basai lobes subsemiorbicular or 

 rotundate-triangular, the primary veins 12—15 on a side, the spadix with 

 the féminine inflorescence without or with very few slender staminodes 

 which are about as long as the ovaries and slightly clavately thickened at 

 the apex, the masculine inflorescence with the fertile and stérile portions 

 somewhat longer, the staminodes subprismatical-obpyramidal, with the apex 

 obtusely angular, truncate, more or less distinctly concave at the centre, 

 especially in the higher ones.

If the plant now cultivated in the Buitenzorg Gardens under this name, 

 flowering May 1920, is the same as that on which Engler based this 

 species, the description will be as follows: 



Relatively small herb with a very short caudex. Leaves with the 

 pétiole shorter than the lamina, 6-10 cm. long, sheathing "/s — '/a its length, 

 dark-green, the anterior side flattened, rather slightly canaliculate, acutely 

 and narrowly 2-cristate-marginate, the crests passing gradually into the 

 lowest primary veins; lamina firm-herbaceous, thinner when dry, elongate- 

 cordate, + 10 — 18 X 3'/2 — ^6'/2 cm., the upper surface rather saturate-green, 

 laxly and minutely pale-puncticulate, glaucous-grey-green towards the sub- 

 falcate, acuminate, apiculate apex, provided with a pale-grey-green, lacerated 

 stripe on each side of and close to the green costa, the stripes laxly ver- 

 ruculose-puncticulate, the under surface pale-green, subglaucous, the base 

 cordate-emarginate, with the lobes semiorbicular or bluntly deltoid, '/2— 1 '/2 

 X l'/4~"3 cm., separated by an acute or subrectangular sinus; primary 

 veins 12—14 on a side, prominent beneath, the basai ones horizontal to 

 radiating, strongly upcurved, the costal ones ascending, connected at the 

 apex by an intramarginal, prominent collective vein ; secondary and tertiary 

 veins finer. Peduncle + 4'/2 cm. long, green. Spathe with the tube obliq- 

 uely ovate, + 2 cm. long, 1 cm. diam., green, slightly longitudinally veined 

 and pale-puncticulate, the base very oblique; lamina conoid-ovoid, 4 cm. 

 long, l'/2 cm. diam, yellowish-green, longitudinally veined, the apex gradually 

 acuminate. Spadix + 3'/2— 4 cm. long; féminine inflorescence conoid, 

 4: l'/2 cm. long, '/2 cm. thick, without staminodes, the lower half or 

 nearly the lower half connected with the spathe; ovaries ovoid, oblongor 

 obovoid, often obtusely angular when seen from above, very pale-green 

 (rather greenish-white) ; stigma sessile, discoid, pale-green or dirty-white; 

 masculine inflorescence clavate, separated from the féminine by a nudate
