This species of annual Sun-flower is nearly related to 
H. tubeformis, from which, according to Mr. Douglas, it 
differs in not having the leaves cordate at the base, or the 
peduncle fistular and thickened. It is a handsome plant, 
growing in the Gardens 6 feet high, with much smaller 
flowers than those of H. annuus. 1t was introduced by 
Mr. Douglas from North-west America in 1827. Our 
drawing was made in the Garden of the Horticultural 
Society, in August 1828.

plant, abounding over the greater part of the temperate 
countries situated in the interior and western coast of 
North America. In sandy parched ground it is a diminu- 
tive, annual, scarcely a foot high; while on the banks of
