]90 ci. CONVOLVULACEJE. (C. B. Clarke.) [Argyreia* 



$ T. n. 22 have the leaves densely hairy, almost shaggy, fulvous beneath; while 

 here those of n. 24 are strigose green beneath ; both have very acute sepals. 



20. A. Lawii, Clarke ; leaves elliptic acute base rhomboid or rounded 

 softly strigose on both surfaces, peduncles elongated, cymes small dense, bracts 

 narrowly oblong, sepals | in. ovate obtuse. Argyreia n. 28, Herb. Ind. Or. H. 



The CONCAN and MALABAR, Bababoodan Hills, Law, &c. 



Scandent, subsericeous. Leaves 4 by 2 in., whiter beneath ; petiole 1 -2 in. 

 Peduncles 2-5 in., silky, white, slenderer than in the foregoing species ; bracts f by 

 in. Cyme dichotomous 3-9-fld., with one in the fork ; flowers subsessile. Corolla 

 2 in. and upwards, tubular-campanulate, hairy without. Fruit not seen. Appears 

 closely allied to A. Choisyana, but the sepals differ widely. 



21. A. Choisyana, Wight ms. ; leaves subcordate elliptic-oblong hairy 

 on both surfaces, peduncles 1-3-fld. shorter than the leaves, bracts narrowly 

 oblong, sepals i-i in. elliptic-lanceolate acuminate. Batatas Choisyana, Wight 

 Ic. t. 491. 



MADRAS ; Balaghaut Hills, Wight. 



A twiner, patently hirsute. Leaves 2 by 1 in., subobtuse, densely strigose above, 

 silky somewhat shining beneath ; petiole ^-| in. Peduncles 1-2 in., hirsute, often 

 with 1 or 2 silky shining subfoliaceous bracts remote from the flowers ; proper bracts 

 f by |- in. Corolla nearly 2 in., tubular-funnel-shaped, hirsute without. Ovary 4- 

 celled. Fruit not seen. Neither the leaves, flowers, ovary or bracts of this species 

 resemble those of Iponiaa atropurpurea to which Choisy (in DC. Prodr. ix. 366) has 

 reduced it. 



VAR. ? Wightii ; leaves rhomboid at the base glabrous above sparsely strigose 

 beneath, sepals strigose margins scarious, corolla 2 in. and upwards. Madras ; 

 Condaputty and other hills,- Wight. This may be a new species, but it is only a 

 fragment in flower. 



22. A. Daltoni. Clarke; leaves large elliptic or oblong acute glabrate 

 above fulvous-strigose beneath, peduncles elongate, corymbs lax, bracts nar- 

 rowly oblong persistent, sepals - f in. ovate-oblong. 



CHOTA NAGPORE ; Bundgao in Singhboom, alt. 2000 ft., Clarke. 



A large climber. Leaves attaining 9 by 4 in., base usually unequal cuneate, 

 sometimes rounded, primary nerves very oblique ; petiole 1-3 in. Peduncles 2-4 in., 

 rigid, fulvous-silky; bracts f in., often narrowly subspathulate. Corolla 2 in., 

 shaggy without. Sepals fulvous-strigose in fruit, coriaceous, concave, two inner 

 shorter glabrate on the margins. Berry in. diam., pulpose. Named after Gen. 

 Dalton, Commissioner of Chota Nagpore. 



23. A . cyxnosa, Sweet Hort. Brit. ed. 2, 373 ; grey pruinose-pubescent, 

 leaves ovate-cordate shortly acuminate, peduncles long, corymbs often branched, 

 flowers densely capitate at the ends of the branches, bracts orbicular persistent, 

 sepals ovate obtuse. Chois. Convolv. Or. 46, and in DC. Prodr. ix. 333 ; Wight 

 Ic. t. 839. Lettsomia cymosa, Roxb. Hort. Beng. 13, and Fl. Ind. i. 492, and 

 ed. Carey $ Wall. ii. 82. Convolvulus glomeratus, Wall. Cat. 2257. 



DECCAN PENINSULA, frequent ; Eottler, Wight, &c. DISTRIB. Philippines. 



Scandent. Leaves 2-4 in. diam. ; petiole 1-3 in. Peduncles 1-4 in. ; corymbs 

 1-4 in. diam., sometimes reduced to single heads ; bracts \ in. diam. Sepals \-^ in., 

 somewhat enlarged in fruit. Corolla 2 in., tubular-funnel-shaped, hairy without. 

 Stamens not exserted. Berry f in. diam., pulpose. This is the Convolvulus mala- 

 laricus of Heyne in Herb. Rottler ; and, as it is frequent in the Peninsula, it is pro- 

 bably Convolvulus malabaricus, Linn., though Linnaeus founds his C. malabaricus on 

 a plate of Rheede's, which is A. malabarica, Chois.
