1 to 1| in. long, contracted at the base. Peduncles usually 1-flowcred and 

 sLorter than the leaves. Sepals ovate, the outermost about 3 lines long, the 

 innermost nearly or quite twice as long. Corolla white or pale pink, cani- 

 panulate but contracted into a tube towards the base, nearly 2 in. long, very 

 shortly and broadly lobed or angled. Ovary 2-celIed. Capsule | in. long,

The species is also iu Burmah and S, China. 



5. I. diversifolia, K Br. Prod 487. Stems very slender, trailing or 

 twining, glabrous as well as the foliage. Leaves digitate, with very narrow 

 linear segments, entire or more frequently toothed or pinnatifid, the central 

 one 1 to 2 iu. long, the others much shorter. Peduncles rather short and 

 thick, mostly 1-ilowered. Sepals oblong-lanceolate, acute, nearly equal or 

 the inner ones rather longer. Corolla nearly 2 in. long, contracted into a 

 tube towards the base. Capsule glabrous, globular, nearly as long as the 

 Cixlyx. — Convolvnlns diver si folius, Spreng. Syst. i. 592. 



W. Australia. Islands of the Gulf of Carpentaria, R. Brown. The leaves are nofc 

 unlike those of the slender forms of /. dissecta, to which Choisj refers it, but the flowers 

 are totally different.

The species of this group, many of them much cultivated iu warm countries for thel^^^"" ^^ 

 of their flowers are mostly nearly allied to each other and difficult to define, nor are 

 characters of the series constant, some species having been diffcrcutly placed in F/urri't>^
