AMPELIDE^:. (M. A. Lawson.) 663 



These 3 last species are closely allied to V. cinnamomea and V. elegans, and with 

 them form the binding link between this genus and Pterisantkes. 



SECT. VI. Leaves 1-3-pinnate. 



74. V. rubifolia, Wall, in Roxb. Fl. Ind. ed. Carey, ii. 480 ; Cat. 0037 ; 

 branches and younger parts pubescent, leaves pinnate, leaflets closely and 

 sharply serrate. 



KHASIA MTS., alt. 4-5000 ft., I)e Silva, &c. ; SILHET, Wallich. ASSAM, Masters. 



A large climbing shrub, branches slender, angular. Leaves 6-9 in. ; leaflets 2^-3^ by 

 l-2 in., shortly stalked, 3-5-paired, subcordate-ovate, acute or subacumiuate. 

 Tendrils forked, glabrous above, pubescent beneath. Flowers small, green, umbel- 

 late in slender dichotomous subcorymbose cymes. Fruit the size of a currant, red, 

 turning black. Seed by g in., broadly obovoid, the back rounded and with a 

 spathulate tubercle, the margins transversely rugose, face sharply wedge-shaped, light- 

 brown. 



75. V. cantoniensis, Stem. Bot. Herald Voy. 370 ; whole plant quite 

 glabrous, leaves pinnate or the lower pair of pinnae ternately compound. 

 Cissus cantoniensis, Hook. & Am. Bot. Beech. 175. C. diversifolia, Walp. 

 PL Meyen. 314. Hedera hypoglauca, Hance in Walp. Ann. ii. 724. 



MALACCA, Griffith. DISTRIB. Hongkong. 



Stem slender, cylindric. Leaflets 5-paired, 2-3 by ^-1 in., ovate-lanceolate, coarsely 

 crenate, whitish beneath. Tendrils branched. Flowers small, in dichotomons corym- 

 bose cymes, 5-merous ? Style subulate. Fruit and seed as in V. rubifolia. A spe- 

 cimen in Herb. Hook., marked Khasia, Griffith, is evidently a fragment of the plants 

 collected in Malacca. 



DOUBTFUL OR EXCLUDED SPECIES. 



Cissus ACUTIPOLIA, Poir. / DC. Prodr. i. 630. Description too short for identifica- 

 tion. 



C. WALLICHIANA, Turcz. in Bidl. Moso. is Hedera Helix, L. 



Vms ATROVIRIDIS, Wall. Cat. 6040, is Gymnostemma trigyna. 



V. ERYTHROCLADA, Rurz in, Joum. As. Soc. Beng. 1872, ii. 301, from Pegu (Kurz) 

 is apparently allied to V. obovata, but the description is not sufficient for identification. 



V. TRICHOPHORA, Wall. Cat. 9032, is Gymnostemma trigyna? 



2. PTBRISANTHES, Blume. 



Large scandent or sarmentose plants furnished with tendrils. Leaves 

 alternate, simple or 3-7-foliolate, digitate or pedate. Flowers small, 4-5- 

 merous, inserted on a flat expanded membranous pedunculated rachis, 

 unisexual ; male flowers marginal, often pedicellate ; female sessile. Calyx 

 cup-shaped or obsoletely toothed. Petals separating. Ovary 2-celled ; style 

 very short, stigma capitate. Berry globose or obovoid, 1-4-seeded. 

 DISTRIB. Sp. 5 or 6. Malay and Indian archipelago. 



Very closely allied to Vitis, especially to those forms of the genus in which the 

 flowers are sessile on racemose spikes. Miquel is probably right in uniting it with 

 Vitis. 



1. P. polita, Miq. Ann. Mus. Lugd. Bat. i. 95; whole plant quite 

 glabrous, leaves simple. 



MARTABAN, at Moulmein, Lobb ; SINGAPORE, Maingay. DISTRIB. Sumatra, Borneo. 



An exceedingly slender far-climbing plant. Leaves 4-8 by 2-34 i n -> elliptic-oblong 

 or ovate, acute, subcordate, distantly and spinosely serrate or entire, membranous. 

 Tendrils bearing the red expanded rachis. Flowers 4-merous. Fruit X
