A native of Algoa Bay, where it was found by the late 
Mr. Forbes, who sent its seeds, in 1824, to the Horticul- 
tural Society. It produced its beautiful flowers, for the 
first time, in a stove, in September 1825, when our drawing 
was made, in: the Societys Garden. The packet of seed 
was labelled ** Creeping Cotton.” 
It requires the full heat of a good stove, in which 
situation it forms a suffrutescent stem three or four feet 
high. Cuttings strike with some difficulty under a hand- 
glass. - From the great beauty of its flowers, this is one of 
the most desirable of the Convolvulus tribe. 
We must state, that as the fruit of this plant is unknown, 
there is some doubt of its genus. In habit it approaches 
some of the Léttsomias, especially L. uniflora; but it 1s 
probably a true Convolvulus, or Ipomoea, if that genus 
be retained.
