From specimens communicated to Drs. Torrey and Gray by the Horticultural Society, it was 
described by those authors. From Californian seeds, procured for the same Society by the Collector 
Hartweg, it has now been raised in the Society's Garden, whence it has been also extensively 
distributed among the Fellows. The plant which produced the specimen here represented flowered

from the annearance of the dried specimens.
