This curious species of Tobacco was raised from seed 
sent by William Bird, Esq. from the rocky moyntains of 
North America, to the Horticultural Society. Upon the 
envelope of the seed, it was stated to be the kind from 
which the Indians prepare the finest of their tobacco. We 
find no mention made of it in any of the works of Ameri- 
can Botanists: but it is possible that it may have been by 
them confounded with N. quadrivalvis; from which, how- 
ever, it is truly distinct. It is very impatient of culti- 
vation. In 1823 several plants were obtained from the 
original parcel of seed; in the present year two only 
were raised from the seed sowed in 1823; and now, owing 
to the wetness of the season, only a few seeds have been 
produced. 
Our drawing was made, in the garden of the Horticul- 
tural Society, in June last.
