Spec. Char., Sfc. Stem suffruticose, much branched, procumbent. Branches 

 procumbent, beset with long hairs. Leaves oblong-lanceolate, with rather 

 re volute margins, pilose on both surfaces, green above and paler beneath. 

 Stipules lanceolate-linear, ciliated, longer than the petiole. Flowers large. 

 Calyx shining, rather hairy. Petals imbricate. (Dot's i. p. 312.) A 



very ornamental species, from Tauria,with large pale yellow flowers, which 

 appear from May to October. Sweet says, " It has, most probably, been 

 confused with H. grandiflorum by many authors ; but, when the plants are 

 seen growing together, no two plants need appear more distinct : the pre- 

 sent spreading flat on the ground, and extending its branches round to a 

 great distance, and these being only slightly sufii-utescent at the base; 

 whereas H. grandiflorum grows upriglat, or has its branches spreading and 

 ascendent, forming a neat httle bushy shrub." Plants of this species were 

 in the Fulham Nursery in 1829. 



!U e-i. H. LU^cipuM Horn. The shinmg-leaved Helianthemum, or Sun Rose.

Spec. Char., Bsc Stem suffruticose, procumbent Leaves stipulate, ovate, green, glossy, with revo- 

 lute margins. {Don's Mill., i. p. 312.) The native country of this sort is uncertain ; but it is said 

 to have been in cultivation in British gardens since 182t>. The flowers are yellow, and produced in 

 May and June.

Spec. Char., 8fc. Stem suffruticose. Branches procumbent, hairy. Lower 

 leaves orbicular, upper ones oblong-linear, hairy ; under surface greenish 

 cinereous. Stipules linear-oblong, twice the length of the footstalks of 

 the leaves. Racemes and calyxes hairy. (Don^s Mill., i. p. 312.) A na- 

 tive of the south of France and of Italy, and strongly resembling H. vul- 

 gare; from which, according to Sweet, it is readily distinguished by its 

 broader and flatter leaves. It has been in cultivation since 1752, pro- 

 ducing its bright yellow flowers from June to August.

Spec. Char., Sic. Stem suffruticose, diffuse. Branches rather tomentose, cinereous. Leaves on short 

 footstalks ; upper ones linear-oblong, with revolute margins, acutish ; under surface clothed with 

 canescent tomentum, upper surface rather hispid. Stipules pilose, longer than the footstalks. 

 Racemes loose. Calyxes pubescent, rather hairy ; hairs deciduous. {Do?i's Mill., i. p. 312.) In 

 cultivation since 1800 ; and, according to De Candolle, probably the same as H. nummularium.

Spec. Char., 8)~c. Stem suffl-uticose, branched. Branches ascendent, nume- 

 rous, tomentosely hairy, cinereous. Leaves ovate or oblong, with revolute 

 margins ; under surface canescent, upper surface greenish cinereous. Sti- 

 pules narrow, rather longer than the footstalks of the leaves. Calyxes densely 

 covered with white hairs. Petals obcordate, imbricate, {Don's Mill., i.p.312.) 

 A native of Spain and of the south of France, and in cultivation in British 

 gardens since 1759. It is a very distinct sort, readily distinguished by its 

 large deep-yellow flowers, which appear in June and July, and by its very 

 hairy leaves. Plants of it were in the Chelsea Botanic Garden in 1829.
