Varieties. There is a very handsome double-flowered variety, with pale yellow flowers; and another, 
called Lee’s new double yellow, with dark yellow flowers ; both of which are in general cultivation 
in the nurseries. De Candolle also notices two forms of the species : one with tomentose 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. 
Spec. Char., §c. Stem suffruticose, procumbent, branched, branches elongated. 
Leaves scarcely revolute 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. Racemes loose. 
Pedicels and calyxes pilose. (Don’s Mill.,i. p. 311.) 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 Helianthemum vulgare by 
Ray, who says that the flowers are very seldom white. Sir J. E. Smith 
says, “ It is a variable species, but less so than authors make it.” (Eng. 
Fi., iii. p. 26.) It is a trailing shrub, flowering from May till September. 
The double-flowered varieties ought to be in every collection.

It is a procumbent shrub, with yellow flowers, the petals of which are dis- 
tinct, and the calyxes pilose. It flowers from July to October. Plants 
were in the garden of Mrs. Dickson, of Croydon, in Surrey, in 1826.

A native of the Pyrenees, from which it was introduced in 
1800. It bears a close resemblance to H. vulgare, but is 
larger in all its parts; and its flowers, which appear from 
June to August, are considerably larger, and of a_paler 
colour. It is quite as hardy as the indigenous sorts. Plants 
of it were in the Fulham Nursery in 1828.
