We had great pleasure in naming this new and very curious 

 Genus, in the Botany of Beechey's Voyage above quoted, in com- 

 pliment to a very distinguished American Botanist, and our very 

 excellent friend, Dr Asa Gray. We regret that the male flowers 

 were unknown to us at the time our figure was executed, or they 

 would have been added to the plate. They resemble the male 

 flowers of the Atriplex^ while the female blossoms exhibit a totally 

 diff*erent appearance.
