ensis; but still, I believe, rare in our gardens, and no figure 
has yet appeared in any publication. 
PursH mentions it as inhabiting, but rarely, dry hills from 
Pennsylvania to Carolina; and Mr Ex.iorr gives the same 
stations, from which I infer that he has not himself seen it in 
a wild state. The specimen here figured, flowered in Mr 
SmitH’s Nursery, Ayr, from roots brought by Mr Goxpre 
from the northern part of the State of New York, where they 
grew in sandy woods. 
The genus Calystegia was established by Mr Brown, 
and designed to include particularly our Convolvulus sepium 
‘and soldanella. The learned author, I am aware, mentions 
the Conv. spithameus as doubtfully belonging to it. But as 
the bractee so entirely accord with one of the most essential 
characters of the genus, I have followed Pursu and the au- 
thor of the Hortus Suburbanus, in retaining it in Calyste- 
ta. 
The Cal. tomentosa of Pursu (C. stans, M1cH.), seems to 
be very nearly allied to the present species, as far as I can 
judge from the definition, the principal characters consisting in 
the tomentose rather than pubescent covering to the former, the 
acuminate leaves, and the stem bearing flowers from its lower 
part.
