PENANG, Jack. DISTBIB. Java. 



Branches soft, smooth, upper compressed. Leaves 4-8 by 1^-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 

 % 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 cyme branches is that of a Grumilea. Some of Miquel's synonyms 

 are too unsatisfactory to be quoted : his G. aurantiaca 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. poly carp a, Miq. 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.

MALACCA, Griffith (Kew Distrib. 3042), Maingay (924); SINGAPORE, Wallich. 

 DISTRIB. Sumatra. 



Branches soft, cylindric, smooth. Leaves 2^-3 in., variable in width, dull greenish 

 when dry, coriaceous, nerves indistinct, veins ; petiole ^^ in. ; stipules ovate, ob- 

 tuse, caducous. Cyme much corjmbosely branched, sometimes 6 in. diam. ; peduncle 

 3 in. and less, and the branches angled ; flowers very small, on divaricating pedicels. 

 Calyx-limb truncate. Corolla ^ in., throat villous. Fruit i 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.

 or elliptic-obovate acute or acuminate, nerves 6-8 pair, petiole slender, cymes ter-

pedicelled, fruit small obovoid 8-grooved, calyx-limb very small. DC. Prodr.
