10 G. TING ENS (Spreng. syst. 1. p. 844.) twining, gla- 

 brous ; leaves cordate, acuminated to oval ; umbels or corymbs 

 often twin, at first shorter than the petioles, and at length spi- 

 rally elongated ; glands of filaments one half shorter than the 

 stamens ; follicles cylindrical, spoon-shaped ; stigma simple, 

 oval, mutic, crowning the tube of the corolla, and therefore ex- 

 ceeding the stamens. Jj . *"\ S. Native of Pegu. Wight, and 

 Arnott, contrib. ind. bot. p. 45. Asclepias tingens, Ham. 

 ex Roxb fl. ind. 2. p. 53. cor. 3. p. 34. t. 239. Asclepias

 ploca montana, Roth, in herb. Wight. Microloma Bidaria, Ham. 

 lierb. Tylophora Ariadnes, Ham. herb. Leaves 3-6 inches 

 long, and :i-4 broad. Umbels compound at length. Flowers 

 largish, numerous, pale yellow. Calyx 5-cleft to the base. Co- 

 rolla having ihe tube as long as the column of fructification, fur- 

 nished inside the rim with 5 double pilose ridges, which are 

 ciliated with short brown hairs. Cordate divisions of the corona 

 covering the stamens. Style simple. Follicles ovate-lanceo- 

 late, smooth and fleshy, 4 inches long, and one in diameter. 



Dr. Hamilton, late Buchanan, informed Dr. Roxburgh, that 

 from the leaves of this plant the Burmese prepare a green dye.

$ 3. Corolla ventricose ; throat toothless ; tube without any 

 pilose lines inside. Filaments usually furnished with a fleshy 

 tubercle at the base. The plants referred to this section ought 

 to form, perhaps, a distinct genus; they differ widely from the 

 others in appearance. The pollen masses differ also from the 

 rest of ihe genus, in being comprexsed and spa/ulate ; and the 

 retinacu/a are thickened, and sometimes very long. 



11 G. NIPAULE'NSE (Wall. tent. fl. nep. p. 50. t. 38.) leaves 

 oval or ovate-oblong, acuminated, glabrous, glaucous beneath, 

 and minutely reticulated with fuscous veins ; common peduncles 

 sometimes shorter and sometimes longer than the leaves ; umbels 

 compound, many-flowered ; flowers subcapitate, on short pedi- 

 cels. V> . r *. G. Native of Nipaul. G. columnare, Wall. 

 ascl. no. 73. a. A large, much-branched shrub. Corollas 

 yellow, urceolate, valvate in aestivation.

12 G. COLUMNA'RE (Wall. ascl. no. 73. b. Wight and Arnott, 

 contrib. ind. bot. p. 40.) leaves subcordate at the base, linear- 

 oblong, acuminated, glabrous, pale glaucous beneath, and reti- 

 culated with fuscous veins ; umbels compound, about equal 

 in length to the leaves, many-flowered ; flowers almost sessile. 

 f? . / "\ S. Native of Nipaul ? Very like G. Nipaulense, and 

 differs chiefly in the figure of the leaves. 



Columnar Gymnema. Shrub tw. 



13 G. SAGITTA'TUM (Wall. tent. fl. nep. p. 50. ascl. no. 114. 

 and no. 83. ?) leaves oval or oblong-ovate, attenuated at the 

 apex, glabrous, whitish glaucous beneath, with the veins of the 

 same colour ; peduncles slender, about equal in length to the 

 leaves ; cymes compound, loose, with filiform branches : pedi- 

 cels disposed along an elevated spiral line ; flowers small, 

 usually caducous ; follicles slender, glabrous. fj . ^. S. Na- 

 tive of Silhet. Anthers subsagittate. Cymes puberulous. 

 Corolla subcampanulate, Wall. 1. c.

 14> G. WALLICHH (Wight, contrib. ind. bot. p. 46.) leaves 

 oval, short-acuminated, glabrous, paler beneath, with the veins 

 of the same colour ; cymes raceme-formed ; pedicels disposed 

 along an elevated spiral line ; corolla ventricose, pilose inside ; 

 gynostegium furnished with 5 fleshy leaflets at the base. 

 \2 . / *\ S. Native of Singapore. Wall. ascl. no. 135. un- 

 named. The large fleshy glands or leaflets at the base of the 

 gynostegium or column of fructification, render this a very 

 doubtful species of Gymnema, but the three preceding species 

 have them also, but not so conspicuous.

15 G. FINLAYSONIA'NUM (Wight, I.e.) twining, glabrous; leaves 

 cordate, ovate, acuminated, glaucous beneatli and reticulated 

 with brown veins ; umbels dense, many-flowered, longer than 

 the petioles ; corolla subcampanulate, glabrous ; gynostegium 

 short, naked at the base ; retinacula of pollen masses elongated 

 and spirally twisted in the middle. Ij . ^. S. Native of the 

 East Indies.

16 G. TRINE'RVE (R. Br. prod. p. 462.) stem erect; leaves 

 oblong-lanceolate, 3-nerved, downy ; umbels sessile ; throat 

 naked. J? . S. Native of New Holland, within the tropic, on 

 the sea shore. Perhaps the gynostegium is naked at the base. 



Three-nerved-lezved Gymnema. Shrub. 



17 G.? ATTENUA'TUM (Wall. tent. fl. nep. p. 50.) twining, 

 smooth ; leaves lanceolate, very much attenuated ; corymbs 

 slender, flexuous, rattier longer than the leaves ; corolla some- 

 what rotate, with a naked throat ; pollen masses divaricate, 

 almost horizontal, ovate ; corpuscles bidentate at the apex.
