A lovely hardy annual, or perhaps biennial, introduced by 

 Mr. Thompson, of the Ipswich Nurseries, and sent to me for 

 figuring by my friend Mr. Wilson Saunders, F.RS., of Rei- 

 gate, with whom it flowered in June of the present year. 



The genus Leaventvorthia consists of two species, both 

 natives of the middle and Southern States of North America: 

 one species, L. aurea, is described as having yellow flowers. 

 and the other, L. Michaimi, white or purplish flowers, yel- 

 lowish towards the base, and it is suspected by Dr. Gray that 

 these are varieties of one ; according to the specimens in the 

 Kew Herbarium, however, L. aurea has the margins of the 

 pod waved and a very distinct style ; and L. Michaiaii, the 

 margins of the pod straight and a very short style, whence, 

 notwithstanding the colour of the flowers, I have referred 

 the present plant to L. aurea. Chapman, who notices these 

 differences in the style in his ' Flora of the Southern United 

 States,' also observes that the radicle of L. aurea is straight, 

 and of the other slightly curved.
