P. Fendleri {Faidlcr's F.) — This is a recently-introduced 

 plant of great merit, on account of its dwarf habit and early- 

 flowering tendency. It grows from i foot to i8 inches high, 

 quite erect, having the stems clothed with deeply glaucous 

 leaves. The flowers are borne in one-sided racemes of graceful 

 appearance, and are light purple. They begin to open in June. 

 Native of the Rocky Mountains. 



P. glaber {Smooth P.) — A very beautiful species, growing 

 about the same height as the last, but the stems are somewhat 

 decumbent at the base. The leaves are smooth and shining, 

 and narrow egg-shaped. The flowers are deep blue, but vari- 

 able in shade in difterent individuals, if the plants are seedlings. 

 They open in June, and continue in long succession. Native 

 of the Rocky Mountains. 



P. Jeffreyanus {Jeffrey's Z'.)— This is a brilliant plant, but 

 not suited for all localities, being very apt to perish in those 

 that are cold and in wet heavy soils. It grows 2 or more feet 

 high, with glaucous leaves and brilliant purplish-blue flowers 

 in graceful racemes. They appear in June or July, and con- 

 tinue for a month or two. Native of California. 



P. Murrayanus {Aliirrays F.)—K deeply glaucous species, 

 rather difficult to keep, and consequently rare in gardens. It 

 grows about 2}^ feet high. The leaves are deeply glaucous, 

 narrow egg-shaped, rather thinly clothing the stems. The 

 flowers are in graceful racemes, narrow, tubular, and shining, 

 brilliant scarlet, appearing rather late in summer. In all parts 

 of the country it will be necessary to give it a comfortable 

 frame in winter, and a sunny warm position in summer. 



P. pocenis (Crcepi?ig /^.)— This is perhaps the dwarfest of 

 all Pentstemons, being a prostrate creeping plant, forming 

 carpet-like masses of dark -green oblong leaves, an inch or two 

 high. The flowers are small, in small but graceful racemes, and 

 very freely produced in June and July. The plant is perfectly 

 hardy, and easily increased by division. Its dwarf habit ren- 

 ders it very useful for either the front line of mixed borders or 

 for rockwork. Native of the Rocky Mountains. 



P. Scouleri {Scolders F.) — A very handsome but rather rare 

 species. It grows about 2 }^ feet high, quite erect. The leaves 

 are lance-shaped, smooth, the margins sharply toothed. The 

 flowers are lilac or pale purple, in handsome racemes, appear- 

 ing in early summer. Native of North America, and is a 

 tolerably hardy sort, but flowers best from autumn cuttings, 

 even if the plants may be trusted out in winter. 



P. speciosus {Showy F.) — A very handsome and showy 

 plant, growing 2}^ or 3 feet high. The leaves are somewhat
