considering the habits of such plants, is probable ; but it is 

 doubtful whether it will flower well without high heat. 



The peculiar colour of its flowers renders it strikingly 

 different from Ipomoea scahra, HorsfallicB, tyrianthina, rubro- 

 ccerulea, or any of the other showy species now commonly in 

 cultivation ; and its roots, which are said to be like red beet, 

 form a singular part of its character. Such a variety of the 

 Sweet Potato is mentioned by Marcgraaf. 



The whole genus Batatas seems to have large fleshy roots ; 

 the B. edulis, which is the common eatable Sweet Potato, the 

 B. paniculata, which has large turnip-shaped roots that yield a 

 kind of Jalap, and the present plant, are apparently mere types 

 of the prevalent character of the genus, which has been struck 

 off Ipomoea by M. Choisy, principally on account of the ovary 

 being 4-celled, with one seed in each cell, instead of 2-celled, 

 with 2 seeds in each cell.
