2 1 4 Convolvulacecs. [ipontcea. 



In most Tropical countries, but probably originally American. 



It is very doubtful if this beautiful plant be truly native here. I do 

 not trace it in the old books, and even Moon (Cat. 14), who gives both 

 /. Bona-7iox and /. grandi/lora, considers them foreigners ; but he gives 

 his C. grandiflorus for ' Kandy ' as native. It is known as ' Moonflower ' 

 by the English ; the great white blossoms expand in the evening, and 

 wither an hour or two after sunrise. I do not know in what way /. 

 grandijlora^ Roxb. (non Lam.) differs from /. Bona-?iox, L., which was, 

 however, only known to Linnaeus from American specimens. 



/. muricata, Jacq., is cultivated in native gardens in the dry districts 

 for the sake of its swollen fleshy pedicels, which are eaten (C. P. 3580). 

 It is said to be a native of Northern India and Japan, and is well figured 

 in Bot. Reg. iv. t. 290.

Stems long, cylindrical, glabrou.s ; 1. 3-6 in., rotundate- 

 ovate, deeply cordate at base, suddenly acuminate, acute or 

 cuspidate, glabrous, petiole nearly as long as 1., with 2 glands 

 at apex ; fl. very large, on much-swollen glabrous ped., 

 usually solitary rarely 2-4, bracts small, soon falling, 

 peduncle as long as petiole, stout ; sep. about i in., ovate, 

 obtuse, mucronate, glabrous ; cor.-tube about 3 in., limb 

 3^ in. diam.; fil. about 2 in., not exserted ; capsule surrounded 

 by much-enlarged sep. equalling it in length, globose, nearly 

 I in., apiculate ; seeds | in., ovoid, densely covered with a 

 short brown velvety tomentum, and with a marginal fringe of 

 long pale brown hair. 



Near the seacoast; rare. Jaffna (Gardner); Dikwelle, S. Prov. 

 (Thwaites); Trincomalie. Fl. Aug., Sept.; white. 



On most Tropical shores of the Old World. 



Always {!) maritime. Differs from /. Bona-nox chiefly by its seeds. 

 Hermann seems to have collected it (Mus. 52), but there are no speci- 

 mens of his existing. Thw. suggests that the Rivea hypocraterijormis 

 recorded by Choisy from Trincomalie may have been this.

A very large twiner, stems rough with blunt prominences, 

 glabrous, young parts slightly pubescent ; 1. 3-5 in., ovate, 

 cordate with rounded lobes at base, caudate-acuminate, very 

 acute, nearly glabrous above, pubescent and somewhat 

 glandular beneath, petiole nearly as long as 1., pubescent ; 

 sep. I -I I in., equal, ovate-oblong, obtuse, mucronate, pubescent, 

 with a few glandular pits at base; cor.-tube 2-2^ in., limb over 

 4 in. diam., stam. not exserted, fil. about i in., capsule sur-
