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

 Pedate leaves occur, and 1-fld. peduncles are not rare in I. 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. 



IMPEEEECTLT 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-flcl. — N.W. Himalaya; 

 Sirmore, alt. S-.IOOO ft., EdgefiDorth. Leaves 4 in., entire; petiole 2f in.' Pedimcles 

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

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

 striated, glabrous. CoroUa not seen. Frtiit (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. Frodr. ix. 388 ; wholly villous-hairy, 

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

 the leaves. — liaised from Indian seeds, in Hort. Boccon. 1825. 



3. I. cuspiDATA, Bon. Frodr. 98 ; Chois. in DC. Frodr. 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. Plores rose, a little larger than in /. cocoinea. No Nepal plant with a 

 very short style and linear sepals will answer to this. 



4. I. MULTiPLORA, Boxb. Fl. Ind. ed. Carey ^ Wall. ii. 89, and lo. Ined. in Herb. 

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

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

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

 Peduncles 7-8 in. (in Eoxburgh'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 HooTceri ; but it is not probable that Eoxburgh ever 

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

 hedges." It is not WaUieh's C. Boxburghii (Cat. n. 1416), which is t^e type of 

 Jrgyreia Boxburghii, Chois.
