This is apparently the only species really indigenons in the Malayan Peninsula. 

 There are, however, four American species which have escaped from cultivation. 

 These are : — 



P. suberosa, L. A small species with diversely shaped leaves, flowers little more 

 than half-an-inch in diameter and ovoid fruits about the same in length. 



P. foetida, L. A species with variable leaves, emarginate at the base, often 

 3-lobed ; recognisable at once by its foetid flowers and 3-leaved fimbriate involucre. 



P. eduliSy Sims. With deeply 3-Iobed serrate leaves, flowers more than an inch 

 across; and globular edible fruit. This is often cultivated under the name of 

 Oranadilla. 



P. quadrangularisy L. A large species with boldly 4-angled stems ; handsome 

 fragrant, purple flowers banded with white, 3 to 5 in. across ; broadly ovate leaves 

 and large oblique ovate-oblong stipules. 



P. laurifolia, L. A more slender species than the last and with smaller flowers 

 of similar colour, with a large 3-leaved or 3-partite involucre of broad segments, 

 and of long filiform stipules; the leaves broadly oblong, entire and shortly apiculate. 



3. Adenia, Forsk. 



Scandent. Leaves entire or palrailobed, usually with two or more 

 flat circular glands on the under surface and with similar glands at the 

 apex of the petiole. Cymes axillary, few or many-flowered, on long 

 peduncles, one or more of which is sterile and tendril-like. Male flower: 

 Calyx tubular or bell-shaped ; limb 5-lobed, lobes leathery, imbricate. 

 Petals 5, free, membranous, 1-nerved, springing from the calyx-tube. 

 Corona a ring of threads arising from near tlie base of the calyx-tube, 

 or wanting. Glands of the disc 5, opposite the sepals, strap-shaped or 

 capitate. Andrcecium cup-shaped, membranous beneath ; filaments 5, 

 linear-subulate ; anthers linear-oblong, 2-celled. Ovary rudimentary or 

 0. Female flower: Calyx and coroZ^a as in the male. Oorowa a mem-, 

 branous fold, springing from near the base of the calyx-tube, or none. 

 Glands of the disc 5, strap-shaped, capitate, opposite the sepals. St ami-. 

 nodes 5, forming a membranous cup surrounding the base of the ovary, 

 above dividing into barren filaments. Ovary globose or elliptic, sessile 

 or stalked; style cylindrical or none; stigmas 3, capitate or flat and 

 dilated. Frnit capsular, 3-valved. Seeds numerous, attached by long 

 funicles to parietal placentas. — Distrib. About 40 species, natives of 

 the tropics of the Old World.
