BOTANY. 77 



forbid us to refer it to any known genus, and it was, therefore, dedicated to Dr. GL W. Hulse, 

 of Louisiana, a zealous cultivator of botany, who gathered it in the mountains of the southern 

 part of California, back of San Diego, and sent the specimen to his friend and correspondent, 

 Dr. Torrey, The characters of the genus, and the distinctive marks (so far as known) of the 

 original species, are here appended. The present plant is only three or four inches high, ex

 grows.
