The speeics is common on the seacoasts of most tropical countries in the New as well as 

 the Old ^Vorld. Although placed by Choisy in Ipomcea, there is generally a more or less 

 developed, spurious, transverse dissepiment between the ovules and young seeds, subdiviJmg 

 each cell into two. 



16. I. carnosa, K Br, Prod. 485. A prostrate or creeping glabrous 

 perennial. Leaves petiolate, mostly ovate or oblong, very obtuse or eraargi- 

 nate, cordate at the base, thick and somewhat fleshy, pcnniveined, and \ to 

 1 in. long, but sometimes with 1 or 2 very prominent basal lobes on each 

 side, and in some specimens (not Australian) long and narrow with a has- 

 tate base. Peduncles short, bearing 1 or rarely 2 or 3 rather large white 

 flowers. Sepals rather narrow, 4 to 5 lines long at the time of flowenng, 

 subsequently enlarged, the outer ones mucronate-acute, the inner ones obtuse 

 and often rather longer. Corolla campanulate, about 1^ in. long. Capsule
