Stl- ARBORETUM AND FRUTICETUM. PART III. 



Varieties. There is a very handsome iloublc-liowcrcd variety, with pale yellow floweri ; ami another, 

 called Lee's new double yellow, with dark yellow flowers ; both of w hich Jire in general cultivation 

 in the nurseries. l)e C'amlolle also notices two forms of the species : one with tonientose pubescent 

 branches, and stipules scarcely longer than the footstalks of the leaves; and another with branches 

 glabrous at the base, but pubescent upwards, and the stipules twice or thrice the length of the 

 petioles of the leaves. 



Slice. Char., <.^r. Stem suffruticose, prociinibent, branched, branches elongated. 

 Leaves scarcely revolutc at the margins ; under surface cinereously hoary, 

 upper surface green, pilose, somewhat ciliated ; lower leaves somewhat or- 

 bicular, middle ones ovate-elliptical, upper ones oblong. Stipules oblong- 

 linear, ciliated, longer than the footstalks of the leaves. Kacemes loose, 

 l^edicels and calyxes pilose. {Don's il ////., i. p. ;J1 1.) The stamens, if 

 touched during sunshine, spread slowly, and lie down upon the petals. {Smith.) 

 Native of dry and hilly pastures throughout Europe, and common in Bri- 

 tain. It was first recorded under the name of Helitinthemuni vulgare by 

 Ray, who says that the flowers are very seldom white. Sir J. E. Smith 

 sa) s, " It is a variable species, but less so than authors make it." {Eng. 

 FL, ill. p. 26.) It is a trailing shrub, flowering from May till September. 

 The double-flowered varieties ought to be in every collection.

Spec. Char., S(c. Stem suffruticose, procumbent. Leaves ovate-oblong, rather 

 pilose. Racemes many-flowered, terminal. Petals narrow, lanceolate,

 It is a procumbent shrub, with yellow flowers, the petals of which are dis-

 A native of the Pyrenees, from which it was introduced in 

 1800. It bears a close resemblance to II. vulgare, but is 

 larger in ail its parts ; anil its flowers, which appear from 

 June to August, are consideial)ly larger, and of a paler 

 colour. It i.s quite as hanly as the indigenous sorts. Plants 

 of it were in the Fulham js'ursery in 1828,
