A really shrubby and, as recorded by Dr. Lindley, though 
it has not proved so this winter (1849-50) with us, hardy 
plant, copiously branched, and at first, with its numerous very 
leafy branches, not having much the aspect of a Pentstemon. 
Such, however, it really is, and a native of California, where it was 
detected by Mr. Douglas in 1831: and does not appear to have 
been found by any traveller since, till Mr. Hartweg met with 
it on the mountain of Santa Inez in California in 1848, when 
seeds were sent by him to the Horticultural Society. It produces 
its bright scarlet flowers among the copious foliage during the 
summer months. 
Descr. A rather weak and straggling shrub ; but with a little 
Support and training it become a very handsome one, with ob- 
scurely four-sided stems and branches. Leaves cordate, acute, nearly 
sessile, subcoriaceous, evergreen (?), strongly and coarsely ser- 
tated.  Flowering-branches numerous, leafy, bearing several 
Opposite dranchlets, which are terminated by a moderately-sized 
flower. Pedicels glandular. Calyz large in proportion to the 
flower, glandular, cut to the base into five rather unequal, lan- 
ceolate, acute, erecto-patent Jobes. Corolla an inch and a half or 
nearly two inches long, bright scarlet: the ‘be almost cylin-
