ARBORETUM AND FRUTICETUM. 



PART III. 



Description, $c. The hardy species are deciduous or sub-evergreen shrubs, 

 generally with trifoliolate leaves and yellow flowers ; there is a great same- 

 ness of character among them ; and, though many are quite distinct, yet it is 

 highly probable that the greater number now recorded as species are only 

 varieties. They are chiefly natives of Europe ; but a few are found in the 

 north of Africa, and they are all hardy or half-hardy. A number of the spe- 

 cies were formerly included under the genus jSpartium, and some under f ytisus, 

 from which they have been separated by Lamarck, whose arrangement as 

 modified by De Candolle, we have adopted in the following enumeration.

Spec. Char., fyc. Leaf trifoliolate, its petiole very short; its leaflets usually deciduous, very narrow, 

 glabrous. Flowers in lengthened terminal racemes. Legumes compressed, 1 3-seeded, rather 

 pubescent, being covered with minute closely pressed down, slightly spreading. (Dec. Prod., ii. 

 p. 145.) A deciduous shrub, a native of the Levant, near the Gulf of Mundania, producing its 



yellow flowers from May to August.

It was introduced in 1817 ; and, in British gardens, grows

:>igr<ti'ing. Vent. Hort. Cels., 1. 17. 

 Spec. Char.,SfC. Leaf trifoliolate. Leaflets linear-sublancec late, silky beneath. Flowers in terminal 

 heads. Legume compressed, so as to be flat, tapered at the base, containing 12 seeds. (Dec 

 Prod., ii. p. 145.) A deciduous shrub, from 2 ft. to 4 ft. high, a native of Mogador, in Spain; 

 introduced in 1812. Its flowers, which are produced from May to August, are yellow, and rather 

 larger than those of the preceding species. De Candolle thinks it is perhaps a species of Cytisus. 



* 3. G. CA'NDICANS L. The whitish-surfaced Genista. 



Identification. Lin. Amo?n. ; Dec. Prod. ,2. p. 145. ; Don's Mill., 2. p. 149. 

 Si/nonymes. Cytisus ciindicans Lin. Sp. ; C. pubescens Mccnch, 

 Engravings. Dend. Brit, t.80. ; and our fig. 267. 



Spec. Char., fyc. Leaf trifoliolate, petiolate ; leaflets obo- 

 vate, pubescent, with appressed down. Branches angled. 

 Flowers in terminal heads, few in a head. Legume 

 hairy. (Dec. Prod., ii. p. 145.) It is allied to G. cana- 

 riensis, but has larger leaves, and scentless flowers. (Dec.) 

 A sub-evergreen shrub, a native of Mogador, Italy, and the 

 Levant. Introduced in 1735, and producing its large 

 scentless flowers from April to July. In British gardens, 

 it grows to the height of 4 ft. or 5 ft. ; and the great ad- 

 vantage of this species is, that it grows rapidly, and flowers 

 freely. In a newly formed garden or shrubbery, where it 

 is desirable to produce a considerable effect the first sum- 

 mer, there are few shrubs better adapted for this purpose 

 than the different species of Genista; provided the plants 

 are done justice to, in all that relates to culture.

Identification. Ait. Hort. Kew., 3. p. 14. ; Dec. Prod., 2. p. 146. ; Don's Mill., 2. p. 149. 



Synonyme. G. triquetra Lain. ? 



Engravings. Curt. Hot. Mag., t. 314. ; and our fig. 268. 



Spec. Char., $c. Branches 3-sided, decumbent, the younger 

 ones villose. Leaves trifoliolate, simple about the ex- 

 tremities of the branches ; leaflets ovate-lanceolate, vil- 

 lose. Flowers in short terminal racemes. (Dec. Prod., ii. 

 p. 146.) A trailing shrub, which, in winter, has the ap- 

 pearance of being evergreen from its somewhat winged 

 and triangular green shoots. It is a native of Spain, 

 Italy, and France; it was introduced in 1748, and, in 

 British gardens, produces a vast profusion of flowers 

 from April to July. No shrub is more ornamental on rock\\ oik ; and when 

 trained to a stake, and allowed to form a head, or grafted standard high
