Probably a cultivated form of /. palmata. Eoxburgh only knew it in cultivation. 

 Pedate leaves occur, and 1-fld. peduncles are not rare in /. palmata. The only re- 

 maining differential character is the colour of the corolla ; but this is by no means a 

 pure yellow in /. dasysperma ; the tube is purplish and there are often purplish 

 streaks on the limb. 



IMPERFECTLY KNOWN AND EXCLUDED SPECIES. 



1. 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. 3-5000 ft., Edgeworth. Leaves 4 in., entire ; petiole 2^ in. Peduncles 

 in pairs from each of the 4 axils on the branch, subquadrangular ; cymes 6-10-fld. 

 bracts in young fruit ; pedicels |-| in. Sepals in., broad-elliptic, shortly acute, 

 striated, glabrous. Corolla not seen. Fruit (imperfectly ripe), much exceeding the 

 sepals, ovoid, glabrous, possibly indehiscent. Seeds 4, glabrous. The example is 

 imperfect, but can be matched with no other Indian plant. 



2 I. COMPRESSA, Gussone; Chois. in DC. Prodr. ix.'388; wholly villous-hairy, 

 stem twining compressed, leaves ovate-cordate entire, peduncles 1-fld. shorter than 

 the leaves. Eaised from Indian seeds, in Hort. Boccon. 1825. 



3. I. CUSPIDATA, Don. Prodr. 98; Chois. in DC., Prodr. ix. 388; leaves cordate 

 cuspidate entire pubescent with rounded lobes, peduncles axillary solitary longer than 

 the leaves many-fld., sepals linear acute hairy, style exceedingly short. NEPAL; 

 Hamilton. Flores rose, a little larger than in /. coccinea. No Nepal plant with a 

 very short style and linear sepals will answer to this. 



4. I. MULTIFLOBA, Roxb. Fl. Ind. ed. Carey $ Wall. ii. 89, and Ic. Ined. in Herb. 

 Kcw ; stems woody twining, leaves broad-cordate downy, peduncles as long as the 

 leaves umbelliferous. Common, native in hedges and forests, Roxburgh. Stem woody, 

 twining up and over trees. Leaves 3-4 in. diam., short acuminated; petiole 2-3 in. 

 Peduncles 7-8 in. (in Roxburgh's picture) ; cyme close, compound ; bracts ; pedicels 

 in. Corolla 2J in., pale rose. Fruit not described nor depicted. Roxburgh's 

 picture might do for Argyreia HooJceri ; but it is not probable that Roxburgh ever 

 obtained that species, and it is hardly possible he would say it was " common in 

 hedges." It is not Wallich's C. Roxburghii (Cat. n. 1415), which is the type of 

 Argyreia Roxburghii, Chois.
