A native of various parts of the hotter regions of America. 
Humboldt and Bonpland found it by the sides of moun- 
tains in Cumana between Caripe and Santa Cruz; it has 
also been observed near Chapultepec in Mexico by Kar- 
winsky. The seeds from which the plant now represented 
has been raised were fathered in Mexico by Mr. Graham, 
and presented to the Horticultural Society. 
Owing to the wetness of the summer of 1830, the species 
did not flower till late in October, and consequently pro- 
duced no seed; but in more favourable seasons, it would 
probably become a hardy ornamental autumn plant. It is 
described by all writers as an annual; and we are not able 
to contradict the statement, the frost having destroyed it 
* Named in honour of Mr. John Tradescant, Gardener to Charles the 
First.
