has 2-3 teeth, several spinulose teeth also at the hastate base. 

 Flowers pale-yellow, 1-3 on a slender peduncle -5-1" long. Sepals 

 glabrous elliptic-oblong ovate or somewhat obovate "IS", or •2-"25" in 

 fruit, deciuu-ent on the thickened pedicel. Corolla S" long (in my

Behar, Hope ! Chota Naj^pur. Singljhum, frequent in open places ! Orissa, near 

 Chilka Lake, Cal. Herb. ! Fl., Fr. r.s. 



Nearly or quite glabrous. Leaves with the excurrent midrib forming the centre 

 tooth. Peduncles slightly hairy, with small persistent bracts 'Oe-'OS" long, often 

 with a branch below the first flower ending in a pair of bracts and a second pedicel 

 thicker than itself subalate with the decurrent sepals (much as uiAnaseia). 



9. I. hastata, nov. comh. Syn. I. angustifolia, Jacq. ; Merremia hastata, 



Hallier, f. 

 Perhaps not specifically distinct from the last, but said to differ 

 by being larger and twining, with larger flowei's "TS", funnel-shaped, 

 yellow with purple eye. Sepals •25-"3". Capsule similar. Seeds 

 similar, glabrous. 



Orissa, near Chilka Lake, Cal. Herb. ! Fl. May (and probably onwards). 

 I have sometimes seen tridentata with the ends of the branches spiral as though 

 it might sometimes climb. 



10. I. caespitosa, nov. comh. Syn. 1. linifolia, Bl. 



A slender twiner, sometimes rooting at the lower nodes, with linear- 

 oblong or narrowly elliptic-oblong leaves 1-2" long, entire except 

 sometimes the base shoi-tly hastate and tip sometimes emarginate. 

 Petiole haii'y, 'l-S". FloAvers yellow, "T-S" long, in slender-peduncled 

 cymes 1-2" long. 



Purneah ! Sambalpur, Cal. Herb. ! FL, Fr. Sept.-Nov. 



Stems usually with spreading hairs, sometimes glabrate (F.B.I.). Pedicels with 

 two very small but conspicuous spreading lanceolate bracts at their base. Calyx 

 ■15-'2" long with oblong rounded sepals. Corolla campanulate, the bands distinctly 

 nerved. Capsule as long as calyx, ovoid, papery, the septum usually evanescent. 

 Seeds usually 4 glabrous. 



11. I. reniformis, Chois. Syn. Evolvulus emarginatus, Burm. (1768) ; 

 Merremia emai'ginata, Hallier, f. ; Convolvulus reniformis, Eoj:" 6. 



The name "emarginatus" appears to be the oldest, but its adoption, besides 

 being less well known and less appropriate, involves yet another combination. 

 Moreover, there is a doubt whether this is not Concolmlus qangeficiof, L. (Amcenitateg 

 Academicce, iv, 306, published about 1760), in which case the name should be 

 gangeficiis. 



A small herb wdth creeping, not twining stems, rooting at the nodes 

 and small, usually reniform, sometimes ovate cordate leaves, and 

 small yellow flowers ■5-75". Capsule •15-'2", subglobose 2-celled. 



Chota Nagpur. Singbhum ! Manbhum, C/arA-e ! Fl., Fr. Sept. -Dec 

 Glabrous or nearly so. L. ■2-75" long or broad, .sometimes up to 1*5" {Clarke),

 Peduncle hardly any, 1-3-fld. Two outer sepals small, lanceolate or oblanceolate, 

 three inner much larger entire or obcordate or 2-lobed, r2" long, ciliate with long 

 hairs. Corolla campanulate. Anther.-^ oblong. Ovary glabrous, tip attenuate
