48 xcv. ASCLEPIADE.E. (J. D. Hooker.) [Heterostemma. 



WESTERN PENINSULA ; the Carnatic, in sandy places, Wight. 



Leaves very variable, 3-5 by 1^-3 in., tip usually rounded and apiculate. 

 Cymes usually sessile, flowers | in. diam. ; coronal processes with an erect acute 

 appendage. Follicles very slender, 4 in. long by -| in. diam., glabrous. Seeds ^ 

 in. long narrowly ovate. 



VAR. zeylanicum ; leaves acute or acuminate, flowers dark purple, appendages of 

 the coronal processes larger obtuse or acute. H. tanjorense, Thwaites Enum. 198. 

 Ceylon, central province, ascending to 4000 ft. 



5. K. Dalzellii, Hook.f. ; branches glabrous or nearly so, leaves broadly 

 or narrowly elliptic or ovate- or oblong-lanceolate acuminate, coronal processes 

 spathulate without an appendage. H. Wallichii, Dalz. $ Gibs. Bomb. FL 152 

 (not of Wight}. Heterostemma, sp. 2, Herb. 2nd. Or. H.f. $ T. 



The CONCAN ; at Vingorla, and Mai wan, Dalzell, Stocks. 



Leaves as in H. tanjorense, of which this may be a variety, differing greatly in the 

 corona, the lobes of which have no appendage proper, though there are traces of 

 swellings at the bases in some specimens and at their backs in others, as if in the 

 latter case the process was reduced and its appendage enlarged. In some specimens 

 the apex is obscurely 3-lobed, in others the tip is subquadrate with a simple or bifid 

 tip, and the sides acutely angled. The follicles appear shorter than in H. tanjorense, 

 but they are not quite ripe in either species. 



41. DITTOCERAS, Hook. f. Gen. Nov. 



A stout pubescent twining shrub. Leaves opposite, long petioled, elliptic- 

 ovate, acute. Flowers large, in sessile umbelliform few-fld. cymes. Sepals 

 minute, ovate, obtuse, glandular within. Corolla rotate; lobes short, tri- 

 angular, subacute, valvate in bud. Corona large, deeply 5-lobed, lying flat 

 on the corolla, lobes orbicular-spathulate, with a minute boss at the base of 

 each. Column depressed. Anthers minute, tips very short, incurved ; pollen- 

 masses very minute, subglobose, sessile on the minute corpuscle, waxy, erect. 

 Stigma pentagonal, included. Follicles sub-cylindric, obtuse, recurved, pericarp 

 very thick fleshy, endocarp hard shining. Seeds very large, narrowly ovoid- 

 oblong, compressed, winged at the rounded base ; coma short.

 sp. 6, Herb. Hook.f. $ T. 



SIKKIM HIMALAYA, alt. 2-4000 ft. ; J. D. H., T. Anderson, Clarke. 



Branches leaves beneath, petioles and pedicels rusty-pubescent. Leaves 4-5 by 

 2-3 in., sometimes cordate, dark green, sparsely hairy above, nerves 4-5 pairs ; 

 petiole 1^-2 in. Corolla l in. diam., sparsely hairy without, dark purple. Follicles 

 4-5 in. long, by f in. diam., green when ripe. Seeds 1^ in. long, black, coma as long 

 as the rest of the seed, hairs spreading andreflexed. Closely allied to Heterostemma, 

 but widely differing in the large flowers, follicles, and seeds. 



42. OXANTHUS, Jtcnth. 



Twining glabrous undershrubs, branches with two lines of pubescence. 

 Leaves opposite. Cymes small, subsessile, few-fld. Sepals small, obtuse or 

 acute. Corolla ovoid-urceolate or disciform, mouth contracted ; lobes 5, very 

 short, broad, valvate. Corona cupular, adnate to the column, spreading, fleshy, 

 tabulate or toothed. Column minute, short, depressed ; anther-tips short, in- 

 flexed ; pollen-masses very minute, one in each cell, semi-ovate, compressed, 

 inner margin pellucid, sessile, waxy, ascending-. Stigma broadly conic, not ex- 

 ceeding the anthers.
