Var. tricolor, N. E. BR., MS. ; Enql., I.c. — Another jDlant cultivated 

 in the Buitenzorg Gardens, flowering and fruiting February and March 1921,

 having the entire lamina spotted, ratlier marbled with dark-green, bright- 

 green and pale-grey-green but so that the bright-green portions are domi-

I hâve not seen an authentic spécimen of this species. Plants from an 

 unknown origin, cultivated in the Buitenzorg Gardens, determined by 

 EnGLER as A. Roebelenii, are distinguished from Engler's diagnosis as 

 foliows: Stems to 1 m. high, 5 cm. thick, erect or at length reclinate, 

 densely foliate at the apex. Leaves with the pétiole T'/g— 20 cm. long, 

 green, with the sheath 6—12 cm. long, narrowly scariose at the edge; 

 lamina elliptical-oblong, to 30X15 cm, somewhat unequal-sided, the apex 

 very shortly acuminate, the upper surface dark-green, maculate; spots pale- 

 greyish-green, minutely darker-spotted or puncticulate, those of the smaller 

 leaves mostly confluent into irregularly flammiform or marbled lines running 

 along the primary veins and the lines commonly confluent again into 

 a very broad, irregularly eroso-lacerated line on each side, medial between 

 the Costa and the margin, as is invariably the case in the larger leaves. 

 Cataphylla linear-lanceolate, shorter than the peduncle, pale-yellow. Peduncle 

 4 — 7 cm. long, green. Spathe elongate-oblong, 372—572 cm. or more long, 

 72 — ^/4 cm. diam., green. Spadix on a stalk 72 — ^/4 cm. or more long; 

 ovaries depresso-globose or -ovate, pale-green, the apex subconically attenu- 

 ated into a short and thick style; stigma broader than the style, slightly 

 foveolate in the middle; masculine inflorescence very pale-green or-yellow, 

 nearly white; berries oblong, when young green, afterwards orange or 

 minium-red, when ripe carmine-red, + I72 cm. long, nearly 1 cm. thick, 



Àglaonema robustum, V. A. V. R. 



Planta robusta, caudice usque 172 m- vel plus longo, basi + 6 cm. 

 crasso, apice foliato. Foliorum petiolus 1772" 2772 cm. longus, vagina + 

 15 cm. longa instructus, supra vaginam teres, antice apicem versus pro

 35—40 X 14—16 cm., medio latissima, utrinque subaequaliter angustata, 

 supra obscure viridis, secus venas pallidius viridi-maculata, maculis plerum- 

 que in fasciis irregulariter erosis confluentibus, subtus laete viridis, basi 

 late rotundato-cuneata, apice obtusiuscula, acuta vel brevissime acuminata, 

 brevissime apiculata ; costa supra leviter depressa, subtus valde prominens, 

 teres; venae primariae + 6—8 utrinque, subtus leviter prominentes, basi
