.'] xcv. ASCLEPIADEJ:. (J. D. Hooker.) 15 



find in its allies, though there are traces of it in T. Kleinii. Fragment of a follicle 

 eylindric, glabrous. 



7. T. Kurzii, Hook.f. ; leaves large broadly elliptic-ovate "broadly cuspi- 

 date coriaceous shining, cymes small, flowers few sessile, calyx nearly glabrous, 

 coronal scales obtuse hardly overtopping the anther-cells, stigma long slender. 



MIDDLE ANDAMAN ISLAND, Kurz. 



I have seen but one specimen, which is nearest to T. Kleinii, differing in the large 

 (4-5 by 2^-3 in.) coriaceous leaves, long ( in.) petioles and nearly glabrous calyx. 



** Corolla lobes with a triangular erose scale adnate to their bases. 



8. T. acuminatus, Benth. in Gen. PI. ii. 747 ; leaves elliptic-lanceolate 

 acuminate quite glabrous shining base acute, cymes branching from the base 

 branches and branchlets very long slender few-fld., flowers pedicelled. Gonio- 

 sternma acuminatum, Wight Contrib. 62; Wall. Cat. 8242; Dene, in DC. 

 Prodr. viii. 504. 



SILHET, Wallich. 



Stem glabrous, pustular. Leaves 4-5 by lf-l in., shining on both surfaces; 

 nerves many, faint, spreading; petiole ~ in. Cymes almost glabrous, nearly 

 equalling the leaves ; pedicels very slender ; bracts very minute. Sepals very small, 

 rounded. Corolla \ in. diam., quite glabrous, lobes lanceolate twice as long as the 

 tube. Coronal scales triangular, shorter than the column. Stigma long, fusiform. 



DOUBTFUL AND IMPERFECTLY KNOWN SPECIES. 



T. ERIOCARPUS, Hook.f. ; leaves elliptic-oblong or oblong-lanceolate aciite at both 

 ends quite glabrous, petiole slender, nerves slender very oblique, follicles long curved 

 terete finely pubescent, seeds linear-oblong tip not contracted. 



TRAVANCORE ; at Courtallan, Wight. 



Branches glabrous, woody, Leaves 2|-3 by 1-1 i in. firm, pale when dry; 

 petiole |-^ in. Flowers not seen. Follicles 5-7 by ^ in. woody. Seeds f in. 

 long. 



T. EOXBURGHTI, Griff. Notul. iv. 68 ; Ic. PI. Asiat. t. 386 f. 4, 5, not of W. A. 

 from Mergui. This, though referred by Griffith to Eoxburgh's Atclepias longistigma 

 (T. Roxburyhii, W. & A.), is certainly not that plant, and is, I suspect, T. GriffitUi. 



? T. WIGHTIANUS, Hook. $ Arn. Sot. Beech. Voy. 200 ; Dene, in DC. Prodr. viii. 

 506 ; stem very slender, young densely rusty -torn entose, leaves small 1-1 in. 

 elliptic oblong cuspidate glabrous above rusty-pubescent beneath, base rounded, 

 nerves 2-4 pairs, slender oblique, petiole in. Specimens in leaf only collected) by 

 Dr. Thomson and myself at the Bor-panee river, Khasia Mts. alt. 2000 ft., quite 

 resemble the Chinese T. Wightianus, which may be known by its very small cymes of 

 flowers, like those of T. himalensis, and its short tomentose pods. 



16. GEXIANTHUS, Hook.f., Gen. Nov. 



Twining shrubs. Leaves opposite. Flowers small, in axillary subsimple or 

 dichotomously branched cymes. Calyx minute, lobes oblong obtuse. Corolla- 

 tube short ; lobes narrow, spreading and recurved, villous to the tip on the 

 inner face, valvate. Corona of 5 scales adnate to the column. Staminal-column 

 minute ; pollen-masses 2 in each cell, minute, waxy. Stigma sessile and capitate, 

 or long and slender. DISTETB. Species 3 or 4 tropical Asiatic and Malayan. 



This genus is distinguished from Toxocarpus by the bearded corolla-lobes and 

 valvate aestivation. 



Stigma sessile, capitate. Cymes very compound.
