Anthera angusta infra medium affixa, liguia brevi late rotundata termi- 

 nata, calcaria loiigiuscula, hand ciirvata hand valde divergentia. Flores albi 

 lobo mediano flavo. 



During the flowering period the plant grows to more than 1 meter with 

 2—3 leaves. The primary tuber of an old plant 35 X 35; elliptic mostly per- 

 pendicularly lengthened 50X25 or 80X35. Rhizomes a finger thick, very 

 numerous spreading in all directions, almost straight often somewhat clavate 

 with perpendicular or horizontal side-branches, which soon are branched 

 again. In sterile plants lumps of a foot in diameter are formed by 

 a repeated branching (PI. VI f. 2). The longest measured rhizome 125X20, 

 of which the side-branches are 50 — 60 X 12. The downwards directed side- 

 branches form bipectinate figures by the alternate large buds of which, 

 however, only those on the under-side develop to tertiary short branches. 



The internodes are short, the nodes somewhat swollen, mostly provided 

 with ring-shaped lacerate rudiments of the scales (see PI. VI). The tops are 

 more or less acute or blunt, not rounded. The colour is very pale-yellow 

 with white tops. The section, also of the tuber, is citrine (236) ; the young 

 offshoots white yellow. 



The leaves are elliptical-lanceolate, but broadest above the middle; very 

 long-acuminate towards the base and passing very gradually into the canali- 

 culate petiole; acuminate towards the apex ending in a short filiform cusp. 



In a specimen of the Bot. garden, which grows in the shade of the 

 woodgarden and which had still two leaves only, these leaves were 700 X 180 

 and 500X160, viz. from the top to the liguia, being the base of the leat 

 so much lengthened and narrowed, a well-marked limit of the petiole is 

 wanting. The leaves of another older plant with 4 leaves, were 605X160, 

 700 X 185, 740 X 180, 770X556 and the petioles respectively 80, 190, 300, 380, 

 a diameter of 25 mm. being taken as a limit between the blade and the 

 petiole. P. was here thus 3 in the oldest leaf, 5 in the youngest, average 

 rather more than 4. In another plant with 6 leaves the average lenght 

 of the leaf was 580 X 150 (P = 3.8.) ; petiole 225. Sheath between 500 and 650. 



As be said these leaves grow in the shade. 



Of a sterile rhizome (91 H) (of "temu po/;" from Djocja) which grew on 

 an open sunny spot, the length of the leaves at a plant of 7 leaves, was: 

 350X 180, 340X150, 440 X 190, 570 X 192, 600 X 190, 650 X 170; 

 the petioles from 100 to 200. Here in the 4 oldest leaves P. is 2.2; in the 

 three youngest 3.3. In a fourth sterile plant (of temoe mangga from 

 Batavia) the smallest leaf was 510X180, the largest 700 X 140, the average 

 of 7 leaves 3.5. The membranous edge of the sheaths protrudes laterally 

 rather far beyond the base of the petiole and passes into the broad lunate 

 liguia; the latter is densely ciliated along the whole edge, also the edge 

 of the sheath is ciliated but less densely-.
