of the Thames as on the rude banks of the Columbia and 
Multnomah. 
We are informed by Mr. Douglas, that “ this hand- 
some and strongly marked species, in its native country is 
not so plentiful as many others. In the dry, gravelly, or 
rocky channels of mountain torrents in the Rocky Moun- 
tains, lat. 47° north, and at the base of the Blue Moun- 
tains on the banks of the Kooskooskee river, 6300 feet 
above the level of the sea, it occurs frequently.” 
Introduced in 1827. It flowered in the Garden of the 
Horticultural Society for the first time in June 1829, where 
our drawing was made. 
It is a hardy perennial, increased by seeds, or division 
of its roots. 
. The following list of the Pentstemons that have been 
found by Mr. Douglas, and which are now growing in the 
Garden of the Horticultural Society, will shew the extent 
to which our Gardens have been enriched with them.
