Schismatoglottis rotundifolia, ENGL., in Pflzrch., LV (IV, 23 Da) Arac- 

 Philod.-Homal.-Schism., 122. 



Plants cultivated in the Buitenzorg Gardens under name of Sch. 

 rotundifolia EnGL. are distinguished from Engler's description by the 

 following characters: Pétiole 5 — 7 cm. long, sheathing '/s— "/s its iength, 

 when young red, adult viridescent, the ventral side narrowly 2-marginate, 

 for the rest densely and very minutely glandular-puberuious, as are the 

 Costa and primary veins beneath; lamina broadly cordate-ovate, S'/q— 7'/2 

 X 4-6 cm., blunt, deciduously apiculate, the basai lobes semiorbicuiar, 

 ^j^—X^I^ X l'/2— 2'/2 cm., separated by a very narrow sinus with an acute, 

 shortiy linear-subulate corner; upper surface dark-green, opaque-velutinous 

 by crowded, very minute, rounded papillae (as in Homalomena humilis 

 HK. F., includ. var. velutina) and provided with numeroiis scattered, white 

 points; under surface pale-green; primary latéral veins less numerous, 

 5—7 on a side. — Spathe and spadix unknown. 



Schismatoglottis batoensis, ENGL., in Pflzrch, LV (IV, 23 Da), Arac- 

 Philod.-Homal.-Schism., 111. 



Engler's diagnosis of this species should be completed as foliows: 

 Pétiole 20—30 cm. long, when young densely, shortiy puberuious, 

 at Iength rather glabrescent; lamina when dry herbaceous, ovate- or 

 occasionally subsagittate-cordate, 16—22 X 9—11 cm. (in the spécimens on 

 hand), with the basai lobes semioblong, sometimes obtusely triangular, 

 about '/y— '/4 ^s long as the antical lobe; costa and the lower part of 

 the primary veins beneath (the costa densely, the veins sparingly) shortiy 

 puberuious; primary veins many on a side, upcurved towards the apex, 

 the lower radiatiiig, the lowest much deflexed, the costal ones spreading. 

 Peduncle at Iength to 15 cm. long. Spadix (young) 5'/2 cm. long, with 

 the masculine inflorescence long and slender, subcylindraceo-fusiform, 

 (young) 4 cm long. 



Schismatoglottis grandiflora, V. A. V. R. 



Herba + 30 cm. alta, caudiculo + 5 cm. longo, '/a cm. crasso. Fo- 

 liorum petiolus 10—25 cm. longus, vagina 3— 4 cm. longa instructus, ceterum 

 brevissime et decidue glanduloso-puberulus; lamina in sicco tenuiter her- 

 bacea, cordato-ovata, usque + 12'/2— 18 X 5 — 9 cm., supra obscura, 

 immaculata, subtus pallidior, apice breviter acuminata, lobis posticis sub- 

 semiorbicularibus, ^/4— 2'/2 X l'/2— 4 cm.; costa venaeque primariae subtus 

 brevissime et decidue glanduloso-puberulae; venae primariae 8 — 12utrinque, 

 apicem versus sursum curvae, apice vena collectiva crassa, intramarginali 

 unitae, basales radiantes, ceterae ascendentes; venae secundariae, tertiariae 

 et quaternariae sensim graciliores. Pedunculus 2—3 cm. longus. Spatha 

 i: 12 cm. longa; tubus obconoideo-obovatus, 4 cm. longus, fere l'/a cm. 

 amplus; lamina explanata oblonga, 8 cm. longa, 3 cm. lata, apice abrupte.
