ARBORETUM AND FRUTICETUM. 



PART III. 



Derivation. From corona, a crown, in reference to the disposition of the flowers in crowns, or umbels, 

 at the tops of the peduncles. 



Description, $c. The ligneous species are hardy or half-hardy, deciduous 

 or subevergreen, shrubs, natives of the south of Europe or Asia, with inipari- 

 pinnate leaves, and flowers on pedicels disposed in umbels placed on axillary 

 peduncles. They are all highly ornamental, and most of them produce seeds 

 in England, by which, or by cuttings, they are easily propagated.

Spec. Char., Sfc. Shrubby, gla- 

 brous. Its leaves are at- 

 tended by minute stipules, 

 and have 5 7 obovate leaf- 

 lets. Its flowers are yellow, 

 disposed 3 upon a peduncle. 

 The claws of the petals are 

 thrice as long as the calyx. 

 The legume is rather cylin- 

 drical than compressed, and 

 its joints separate slowly and 

 unobviously, but they do se- 347 

 parate. It is spontaneous in 

 hedges and thickets of middle 

 and southern Europe, and of Tauria. (Dec. Prod.,\\. p. 309.) Introduced 

 in 1596, and flowering from April to June. Height 10ft. Before the 

 flowers are expanded, the corolla is partly red externally, mostly so towards 

 the tips of the petals ; and the mingling of the yellow flowers, with flower 

 buds more or less red, and the elegant foliage, render this hardy shrub a 

 very desirable one for its beauty. Perhaps it flemishes most in a sunny 

 sheltered situation, ami a dry soil. It bears clipping pretty well, and would 

 form a beautiful hedge. Plants, in the London nurseries, are 9d. each ; 

 at Bollwyller, 50 cents ; and at New York, 37^ cents.

Spec. Char.y fyc. Shrubby, glabrous. Branches rush-like, 

 round, bearing but few leaves ; the latter are attended by 

 minute stipules, and have 3 7 leaflets, that are linear ob- 

 long, obtuse, and rather fleshy; the lowest leaflets being 

 rather distant from the base of the petiole. The flowers 

 are yellow, 5 7 in an umbel. The claws of the petals are 

 scarcely longer than the calyx. The legume is rather com- 

 pressed, and its joints separate obviously. (Dec. Prod., ii. 

 p. 309.) The whole plant is very glaucous. Native of the 

 south of France, and introduced in 1756. It grows to the 

 height of 2 ft. or 3 ft., and produces its bright yellow flowers in June and 

 July. It deserves a place in collections, oti account of the singularity of 

 its rush-like slender branches, which, like those of /Spartium ^'unceum, are 

 partly destitute of leaves. 



App. i. Half-hardy ligneous Species of' Coromlla. 



The half-hardy species of this genus are eminently beautiful, and some of them have been 

 known to live for years in the open border, in a dry soil, in the neighbourhood of London. Against 

 a wall, they will live with very little protection, producing their beautiful yellow flowers early in 

 spring (one species, C. stipularis, in March) ; and continuing flowering throughout the sumiiicr. 

 As they produce abundance of seeds, a stock of plants may always be kept in pots or cold-pits, and 

 turned out into the open borders, where they will flower freely throughout the summer ; and, if they 

 should be killed during the succeeding winter, the loss can easily be supplied
