Tue genus Convolvilus, (80 called @ convolvendo, because 
many of the species are twining) contains a vast number of species, 
of which about sixteen are natives of this country. The one 
under present notice, derives its specific appellation from the shape 
of its leaves, which are frequently panduriform, or fiddle-shaped. 
The root is perennial, very large, cylindrical, and full of longi- 
tudinal fissures. It is generally about the thickness represented in 
the plate, and about two or three feet long, branched at the bottom ; 
(Of a yellow-ochre colour: I have seen specimens, however, of 
greater dimensions. The stem is twining, often procumbent on the 
earth, and not unfrequently climbing round fence-posts. It is round, 
of a greenish-purple colour. The leaves are broad, heart-shaped, 
entire, lobed, panduriform, somewhat acuminate, (deep green 
above and lighter underneath) situated on long petioles. Flowers.
