part 2. p. 79. 
‘This is an inhabitant of San Pedro, Sonora, New Mexico, 
where it was detected by Mr. Charles Wright, whose fine collec- 
tions from that region are worked up into two valuable memours, 
under the title above quoted, by Dr. Asa Gray. Seeds were 
sent to us by Dr. Gray, and the plant pro ved hardy, flowermg in 
September. It has too much of the aspect of our common Flea- 
banes ever to become a general favourite. The species of the 
genus are chiefly inhabitants of South America, but extending 
into Mexico and California, and along the valley of the Mis- 
_ SISsippi.
