1. SaLaCIa vraiNEA, Wall. Cat. 7267. A glabrous scandent 

 shnib. Leaves membrauoas, usually alternate, lanceolate, shortly and 

 bluntlj acuminate, entire, the base cuneate ; main nerves 5 to 7 pairs 

 oblique, faint; length, 2"5 to 4 in., breadth "8 to 1 "5 in., petiole '2 to 

 •3 in. Flowers '15 in. in diam., on thin pedicels "3 in. long, usually 

 solitary or in groups of 2 or 3 (rarely in cymes), from minute bracteo- 

 late tubercles, axillary or extra- axillary. Calyx cupular, flat, with 5 

 triangular concave lobes. Petals 5, rotund or ovate, thin, larger than 

 the calyx-lobes. Disc very convex, fleshy, glabrous, witli a- pale zone 

 at the base. Stamens 3 ; the filaments very bi oad, flat, triangular, 

 eiect ; anthers transversely oblong, dehiscing by 2 transverse 2-celled 

 apical slits. Ovary sunk in the disc, 3-angled, conical ; stigma small. 

 Fruit (young) sub-globular, glabrous. Laws, in Hook. fil. Fl. Br. Ind. I.

The alternate leaves are the best mark of the plants thus named. 

 I think it however possible that two species are included under these 

 alternate-leaved specimens. Those with flowers in short cymes may 

 belong to a different plant from -those with flowers solitary or on tuber- 

 cles. The materifil is not good ; and, in the absence of complete flower- 

 ing and fruiting specimens, it is diflBcult to differentiate species of 

 Salacia when the leaves present no good head marks, as the structure 

 of the flowers is very much alike in many species.
