ARBORETUM AND FRUTICETU AT. 



PART III. 



Description, eye. 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 Spartium, and some under Cj tisus, 

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

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



st I. G. parviflo'ra Dec. The small-flowered Genista.

Spec. Char., Ac. 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 

 vellow flowers from May to August. It was introduced in 1817 j and, in British gardens grows 

 to the height of 6 ft. or 7 ft. 



2. G. clava^ta Poir. 



The club-shaped-calyxed Genista.

Identification. Poir. Supp., 2. p. 717. ; Dec. Prod., 



Synom/me. Spartium sericeum rent. Hort. Cels., t. 17., but not of Ait. 



Engraving. Vent. Hort. Cels., t. 17. 



Spec. Char.,8fc. Leaf trifoliolate. Leaflets linear-sublancer late, silky beneath. Flowers in terminal 



heads. Legume compressed, so as to be flat, tapered at the base, containing 1 2 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. 



st 3. G. ca'ndicans L. The whitish-;rar/ac6Y/ Genista. 



Identification. Lin. Amcen. ; Dec. Prod., 2. p. 145. ; Don's Mill., 2. p. 149. 

 Synonymes. Cytisus candicans Lin. Sp. ; C. pubescens Moench. 

 Engravings. Dend. Brit, t.80. ; and owx 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- 

 densis, but has larger leaves, and scentless flowers. (DecJ) 

 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. 



-* 4. G. tri'quetra Ait. The triangular-s/ewwcY/ Genista. 



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



Si/nonyme. G. triquetra Earn. ? 



Engravings. Curt. Bot. Mag., t. 314. ; and our yj#. 268. 



Spec. Char., Sf-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. I W>.) 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, 

 [taly, and France; it was introduced in 1748, and, in 

 British gardens, produces a vast profusion of flowers f^ 

 from April to July. No shrub is more ornamental on rockwork ; and when 

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