Probably a cultivated form of Z. palmata. Roxburgh only knew it in cultivation. 
Pedate leaves oceur, and 1-fld. peduncles are not rare in Z. palmata. The only re- 
maining differential character is the colour of the corolla; but this is by no means a 
Pure yellow in Z. dasysperma ; the tube is purplish and there are often purplish 
streaks on the limb. 
IMPERFECTLY KNOWN AND EXCLUDED SPECIES. 
l. I. ? BIPEDUNCULATA, Clarke; large glabrous twiner, leaves ovate cordate acute, 
peduncles 2 in. paired in each axil, cymes dichotomous many-fld.—N.W. HIMALAYA ; 
Sirmore, alt. 35000 ft., Edgeworth. Leaves 4 in., entire; petiole 2} im. Peduncles 
" Pairs from each of the 4 axils on the branch, subquadrangular ; cymes 6-10-fld. 
tacts 0 in young fruit; pedicels 1-3 in. Sepals } in., broad-elliptie, shortly acute, 
striated, glabrous. Corolla not seen. Fruit (imperfectly ripe), much exceeding the 
“pals, ovoid, glabrous, possibly indehiscent. Seeds 4, glabrous.— The example is 
Imperfect, but can be matched with no other Indian plant. 
2 1. COMPRESSA, Gussone; Chois. in DC. Prodr. ix. 388; wholly villous-hairy, 
um twining compressed, leaves ovate-cordate entire, peduncles 1-fid. shorter than 
* leaves.—Raised from Indian seeds, in Hort. Boccon. 1825. 
3. I. CUSPIDATA, Don. Prodr. 98; Chois. in DC. Prodr. ix. 388; leaves cordate 
“Uspidate entire pubescent with rounded lobes, peduncles axillary solitary longer than 
® leaves many-fld., sepals linear acute hairy, style exceedingly short. Nevin 
ve ton, Flores rose, a little larger than in Z. coccinea. No Nepal plant with a 
"Y short style and linear sepals will answer to this.
