Whole plant tomentose, 6-10 inches high. Leaves generally 
oval, 2 exterior leaves of the calyx linear. Corolla yellow, and, with the 
leaves, longer than in the preceding species. Unless the H. ramuliflomm of 
Michaux has been misunderstood by our Botanists, it requires a careful 
comparison with the preceding species. Excepting in the size of the 
leaves and flowers, our Southern plant differs very little from specimens of 
the H. Canadense which I have received from New-York. 
Grows in dry, sandy soils. Common along the sea-coast; 
flowers April — May* 
Leaves alternate, 
oblong and oval, to- 
mentose underneath ; 
branches short, gene- 
rally 3-flowered at the 
summit ; calyx of the 
fruit globose.
