The genus Daka has been confounded with Psoralea, 
from which it diflPers essentially in its monadelphous stamens^ 
and in the tube of these stamens bearing the alse and carina. 
It has a still nearer affinity with Petalostemon, in which the 
petals are likewise adnate with the stamens, and in which, as 
well as in the present genus, the leaves are furnished with 
glands, but, besides that the point of their insertion is diffe- 
rent, Petalostemon has but 5, not 10, stamens. 
All the species of Dalea are natives of either North or 
South America : the present individual is indigenous to the 
latter country, where it was, if I mistake not, first detected by 
Humboldt and Bonpland. It is, I believe, still rare in 
our gardens. The figures here given were made from fine spe- 
cimens communicated to me by Mr Shepherd of the Liver- 
pool Botanic Garden, in the month of September 1822.
