This interesting dwarf plant has been described as a bien- 

 nial ; and though it will be found tolive and flower for more 

 than two years, yet its existence is but of short duration ; it 

 would therefore better support the appellation of a short-lived 

 perennial. The present plant and the CE. macrocm-pa have 

 been imagined by some persons to be the same ; the flowers 

 of both are similar in appearance and colour, but the strag- 

 gling habit of growth and the narrowness of the leaves of the 

 missourensis will mark a sufficient distinction. During the 

 months of July and August the prostrate branches of the mis- 

 S02ire7isis are abundantly decorated by very numerous and lux- 

 uriant yellow flowers, which become trul}-^ conspicuous from 

 their size, and particularly so from their being produced on a 

 plant of such humble growth. By intermixing this species 

 with the CE. caspitosa (a plant similar in its habit of growth, 

 but bearing a white flower) a pleasing and beautiful group for 

 ornamenting small beds on a lawn or in a flower-garden may 

 be obtained. The careless mixture of the blooms appearing 

 above the dark green leaves, through which the elegantly 

 twining purple stem is casually seen, produces a beauty that 

 every lover of the flower-garden must view with admiration. 

 The rock-work of a garden will also receive a considerable 

 additional charm by a judicious decoration with these elegant 

 little traihng plants. These species of (Enotlicra require an 

 earth tolerably rich : mellow loam, rotten manure, and decay- 

 ed leaves will form a good composition. As there is no cer- 

 tainty of raising a supply by separating the roots, it is advisa- 

 ble to increase these plants by cuttings, which if planted in an 

 earth somewhat sandy, placed under a hand-glass, and partially 

 shaded, will readily strike : they should be kept in pots under 

 the protection of a frame during the first winter, after which 

 they will thrive well in the open border. This species was 

 discovered by Mr. Nuttall growing freely near the banks of 

 the Missouri, from whence it takes its name: it was introduced 

 in 1811. This figure was taken from a specimen flowering at 

 Messrs. Whitley, Brames, and Milne's Nursery, Fulham.
