3. C. parviflorus, Valil ; Chois, in BC. Prod. ix. 413. A tall twiner, 

 glabrous or slightly pubescent. Leaves on rather long petioles, cordate- 

 ovate, acuminate, entire, membranous, 2 to 3 in. long. Peduncles about as 

 long as the leaves, bearing a deuse cyme of numerous small flowers. Bracts 

 minute. Sepals ovate, acuminate, pubescent, 3 to 2-J- lines long. Corolla 

 very open, above \ in. diameter. Stamens rather long. Stigmatic lobes . 

 linear-oblong, recurved, much shorter than in C. e7'iibescens. Capsule small, 

 completely 2-celled, opening in 4 valves, which are sometimes split but much 

 less so than in a midtivalvis.—C. muUivalvis, var. j3, R. Br. Prod. 483.

The species is widely dispersed over E. India and the eastern Arehipelngo. Tlie flowers 

 are usually described as white, but are said to be blue by Choisy, 1. c, and pink by F. Mueller 

 (Fragm. vi. 99). ^ Sy ^ i 



Sect. II. Calystegia.— Bracts or bracteoles 2, enlarged and enclosing 

 the calyx. Dissepiment of the ovary usually incomplete. 



4. C. marginatus, Sjjreng. Si/d. i. 603. A glabrous twiner. Leaves 

 on rather long petioles, narrow-lanceolate or broad and trinngidar, hastate or 

 sagittate, the basal anricles or lobes acnte, diverging, and often lobed, tlie 

 whole leaf usually li to 2 in. long, but when luxuriant twice as large. 

 Peduncles rarely exceeding the petiole. Bracts very broadly cordate-ovate^, 

 from scarcely longer than the calyx to twice as long. Sepals rarely above 6 

 hues long. Corolla about f in. long. Ovary very imperfectly 2-ceIle(l.

The species is also in Norfolk Island and in New Zealand. Some specimens have the 

 aspect of some vaneties of C. erubescens, but are at once distinguished by the large bracts. 



5. C. sepium, Linn. Sp. PL 218. A tall rather slender herbaceous 

 twmer, quite glabrous or very slightlv pubescent, with a creeping perenmj^l 

 rootstock. Leaves from broadly ovate'-triangular to lanceolate-hastate, acutely 

 acuminate, cordate with angular basal auricles or lobes, mostly 2 to 4 in. oi!g 

 but sometimes lai-ger. Peduncles longer than the petioles and often as loi% 

 as the leaves, beanng a single large flower of a pure white or more or l''»
