WESTERN PENINSULA, from Canara southwards. CEYLON, ascending to 4000 ft. 

 EASTERN PENINSULA, from Tenasserim southwards to Singapore and Penang. DISTRIB. 

 Malay Archipelago. 



A twining shrub, 10 ft. and upwards ; branches slender, smooth pale. Leaves 2- 

 3 by f-1^ in., greenish or yellowish when dry, thin or coriaceous, base far produced 

 on the petiole, nerves faint, veins inconspicuous ; stipules ovate, caducous. Cymes 

 broad, 2-3 in. diam., rachis and branches angled ; bracteoles caducous. Flowers very 

 small, greenish. Calyx-teeth minute. Corolla-tube in., villous within. Fruit ~ in., 

 white, fleshy. Seed dorsal ly 4-grooved, ventrally concave ; albumen equable. Some 

 of Wallich's 8381 and 8384 are no doubt young states (flowerless) of this, or possibly 

 of P. polycarpa. 



18. P. lyiaing ayi. Hook./.; climbing, shoots petioles and cymes hairy, 

 leaves elliptic-lanceolate acuminate at both ends, nerves 8-10 pair, stipules per- 

 sistent connate membranous toothed, cymes axillary small peduncled, fruit 

 broadly ellipsoid 8-grooved, calyx-limb large, lobes broad recurved. 



SINGAPORE, Maingay. 



Branches slender, smooth. Leaves 2-3 by ^-1| in., rather thin, narrowed into the 

 very short slender petiole ; nerves faint ; stipules pubescent. Cymes almost tomen- 

 tose ; peduncle slender, compressed ; branches few, opposite ; bracts linear, persistent. 

 Fruit subsessile, | in. long ; calyx-limb cupular, pubescent. Seed as in P. sarmentosa. 



19. P. ovoidea, Wall. Cat. 8383 ; climbing and rooting, branches leaves 

 beneath and cymes villous, leaves petioled elliptic or ovate cuspidate, nerves 5-6 

 pair, cymes terminal small sessile or peduncled umbellately branched, flowers 

 subcapitate, fruit small pedicelled ellipsoid 8-grooved, calyx-limb with erect 

 acute teeth. 



SINGAPORE, Wallich; MALACCA, Maingay (Kew Distrib. 923). DISTRIB. Malay 

 Archipelago ? 



Branches slender ; pubescence spreading, dark, rufous when dry. Learns l-2 

 in., brown especially beneath when dry, coriaceous, margin often recurved, base acute 

 obtuse or subcordate, nerves strong beneath ; petiole - in. ; stipules connate, cadu- 

 cous. Cymes with spreading stout compressed branches ; peduncle 1 in. or less ; 

 bracteoles elongate, linear, very persistent, tomentose ; flowers very small. Corolla- 

 tube pubescent, villous within. Fruit in., pubescent; calyx-limb cupular. Seed as 

 in the section. 



20. P. morindaeflora, Wall. Cat. 8438, A. B. 0. in part ; climbing, 

 rooting, quite glabrous, leaves petioled elliptic obtusely acuminate shining, 

 nerves 5-7 pair, cymes terminal subsessile and pedicelled small, flowers capitate 

 at the end of the short branches, fruit small ellipsoid 8-grooved, calyx-limb small. 

 ? Psychotria, Wall. Cat. 8355. 



PENANG and SINGAPORE, Wallich, Porter. 



Branches smooth, slender, dark brown when dry. Leaves 3-5 by l-2 in., coria- 

 ceous, usually red-brown when dry, base acute, nerves slender; petiole - in.; 

 stipules connate, caducous. Cymes with few short or long spreading compressed naked 

 branches bearing globose heads in. diam. of small flowers ; bracts and bracteoles 

 linear, caducous. Calyx-limb truncate, obscurely toothed. Corolla-tube glabrous, 

 mouth villous. Fruit ^ in. long, sessile or peduncled. Seed as in the section. 

 Amongst "Wallich's specimens are some with sessile and others with pedicelled fruit ; 

 it is possible that these may belong to different species. His No. 8355 from Singapore 

 has narrow oblong-lanceolate leaves, very long (4-5 in.) peduncles, bearing a puberu- 

 lous umbel of 6-10 rays, each ray bearing a head of sessile flowers in. diam.
