obtuse, cymes terminal, peduncle and subopposite corymbose branches stout, 
flowers pedicelled, fruit large subglobose, calyx-limb very small. 
AÀNDAMAN Isranps, Kurz. 
A shrub. Leaves 6-7 by 13-2} in., thinly coriaceous, dull green when dry, nerves 
slender; petiole 5-1 in. Cymes 1-2 in.; branches subopposite, short, dichotomously 
divided; pedicels stout. Calyx-teeth 5, minute. Corolla small. Fruit 4 in. long, 
slightly obovoid, base suddenly contracted. Seeds }-terete,, ventral face flat ; albumen 
ruminate.—The seeds are not very satisfactory. 
15. P. malayana, Jack in Mal. Misc. i. 3; glabrous, branches robust, 
leaves elliptic-lanceolate acute or acuminate, nerves 12-16 pair, axils imperfo- 
rate, stipules large acute or upper apiculate, cymes terminal peduncled many- 
flowered, branches stout lower or all whorled and with whorled branchlets, 
flowers pedicelled and sessile in the forks, corolla-tube elongate. DC. Prodr.

Penane, Jack.—DisrRIB. Java. 
Branches soft, smooth, upper compressed. Leaves 4-8 by 13-3 in., greenish when 
dry, nerves slender; petiole ;—-} in.; stipules coriaceous. Cymes stout, puberulous or 
glabrous, very many-flowered ; peduncle 3 in. and less, and, branches angled or com- 
pressed; bracteoles caducous. Calyx-limb truncate, obscurely 5-toothed. Corolla-tube 
4 in., lobes lanceolate, and throat villous. Fruit ** obovoid, as large as a cherry stone, 
orange-coloured," Wallich.—Jack's description is too imperfect for identification, but 
as Wallich has his aurantiaca from Jack, there is little room for doubt as to this being 
his species. I have seen no fruit, but that of a very similar Bornean species differing 
only in the opposite eyme branches is that of a Grumilea, Some of Miquel's synonyms 
are too unsatisfactory to be quoted: his G. awrantiaca is described as having 10-ribbed 
fruit; of the loose fruits transmitted with his Chasalia expansa to Herb. Kew, one is 
10-ribbed, and does not, I suspect, belong to the plant. 
16. P. polycarpa, Mig. Fl. Ind. Bat. ii. 295 (Grumilea); scandent, 
glabrous, leaves obovate or elliptic-obovate acute or abruptly acuminate, nerves 
5-7, axils imperforate, cymes terminal brachiate, branches elongate, branchlets 
divaricate, flowers pedicelled, fruit very small ellipsoid umbonate. P. obovata,

Maracca, Griffith (Kew Distrib. 3042), Maingay (924); SiwaAroRE, Wallich.— 
-—Disrriz. Sumatra. 
Branches soft, cylindric, smooth. Leaves 23-3 in., variable in width, dull greenish 
when dry, coriaceous, nerves indistinct, veins 0; petiole 1-3 in.; stipules ovate, ob- 
tuse, caducous. Cyme much corymbosely branched, sometimes 6 in. diam.; peduncle 
3 in. and less, and the branches angled; flowers very small, on divaricating pedicels. 
Calyx-limb truncate. Corolla 3, in. throat villous. Fruit } in. long; calyx-limb de- 
pressed, surrounding the prominent exserted obtuse stout disk, as in P. pendula.—This 
species, notwithstanding its ruminated albumen and }-terete seed, must stand next to 
P. sarmentosa. 
Secr. II. Seeds dorsally convex with 4 furrows.

17. P. sarmentosa, Blume Bijd. 964 ; climbing, glabrous, leaves elliptic 
or elliptic-obovate acute or acuminate, nerves 6-8 pair, petiole slender, cymes ter- 
minal subsessile compressed corymbiform or brachiate, branches opposite, flowers 
edicelled, fruit small óbovoid 8-grooved, calyx-limb very small. DC. Prodr.
