144 NEW PLANTS, ETC., FROM THE SOCIETY'S GARDEN. 



crenate-serrate except at the base, which is entire. From the 

 axils of the upper leaves rise solitary stalked labiate flowers, 

 about 2 inches long, with a somewhat cylindrical, striated, 

 5-toothed, hairy, and glandular calyx, and a yellow corolla 

 deeply stained with orange at the upper part. 



One of the best of the hardy herbaceous plants obtained from 

 Hartweg's expedition to California, but too leafy for a bedding 

 out species. It seems best adapted to cultivation apart from other 

 plants, when it forms a deep green summer bush of some beauty. 



Although the flowers are described above as growing singly 

 in the axils of the leaves, yet it is to be observed that each 

 flower is succeeded by five or six others, so that there is a long 

 succession of bloom.

21. Pentstemon azureus. Bentham, Plantce Hartwegia?ice, 

 p. 327. 



Raised from seeds brought home by Ilartweg in June 

 1848, and said to have been collected among the Sacra- 

 mento Mountains in California. 



A smooth, glaucous, erect perennial, about 2 feet high. Leaves 

 linear-lanceolate, quite entire upon the stem, but near the root 

 oblong and slightly heart-shaped at the base. Flowering racemes 

 about a foot long or rather less, slightly downy, with one short 

 peduncle in the axil of each opposite bract, bearing from 1 to 2 

 flowers. The latter are rather more than an inch long, clear 

 violet blue, much deeper in the limb than on the tube. 



This hardy perennial is stated by Mr. Bentham to have been 

 gathered in the dry river beds of the valley of the Sacramento. 

 Hartweg wrote on his seed papers that it was a mountain plant. 

 It is very handsome as a border flower, but, as its narrow foliage 

 is not good, it is best grown among other species, such as Pelar- 

 goniums, &c.
