A rather showy annual, not very frequently seen in 
collections. The flowers are, as may be judged from the 
accompanying figure, of unusual size, and would, if joined 
to a more ornamental foliage, render this plant one of the 
most remarkable among those of the open border. Unfor- 
tunately there is an air of weediness in its general appear- 
ance, which gives it fewer claims to the regard of the 
amateur than might be expected. . 
A native of Cuba, whence it was introduced into the 
Royal Garden of Madrid, from which establishment it has 
been communicated to the rest of Europe. Our drawing 
was made at the Nursery of Mr. Joseph Knight, in 
July last.
