One of the finest of the genus Asclepias : a native of the west _ 
side of the Rocky Rlsintaia where it was detected by Douglas, 
after whom it was named. Our plant is raised from seeds sent 
in 1846 from North-west America by Mr. Burke, then Collector _ 
for the Royal Gardens. It first flowered in the Nursery of 
Messrs. Lucombe, Pince, and Co., Exeter, in whose garden it 
made a fine appearance in the open border. It continues a long 
time in flower. =
