There is a peculiar delicacy in the foliage of this Convoloulus, which renders it well worth the 
care of those who cultivate annuals. If raised in a hotbed early in Spring and placed close under 
asouth wall about the end of May, it will flower abundantly and ripen seeds in the open air: 
ut to insure this, the pot should be plunged in the ground upon a flat tile, filling the hole with 
distance has more or less the appearance of dust. Leaves remote from each other, though appa- 
rently crowded from the number of branches: Petiole about an inch long, its base tinged with 
dull purple, very slender, finely channelled: Lamina from 14 to 3 inches long, yellowish green 
and smooth on the upper surface, paler and pubescent underneath especially while young, cor- 
date-sagittate with the base itself of the sinus prominent, repand-dentate, the point finely mucro~ 
nate, nearly flat. Panicle from 3 to 7-flowered. Peduncle very slender and round.
