 is a beautiful plant, not only on aci'ount of its fine 

 double flowers, but of its habit of growth. It ought to be in every 

 cistacetum.

Spec. Char., S^c. Stem sufFruticose, branched, difFuse. Branches ascending, 

 rather tomentose, canescent. Leaves flat, or hardly revolute at the margins ; 

 under surface tomentosely hoary, upper surface greenish glaucous. Lower 

 leaves ovate oblong, obtuse; upper ones lanceolate, acute. Stipules linear, 

 ciliated, somewhat longer than the footstalks. Calyxes smoothish, but with 

 the nerves pubescent. Petals imbricated. (Don^s Mill.) A procumbent, 

 sub-evergreen, sufFruticose undershrub. Originated in gardens. Height 

 f) in. to 1 foot. Cultivated in 1826. Flowers reddish crimson; May to 

 August. 



A splendid plant, with reddish crimson flowers ; 

 the petals imiiricated, and having a small orange spot 

 at the base of each. Sweet considers it as having the 

 darkest-coloured, if not the handsomest, flowers of 

 the genus. The flowers are also, he says, very large 

 tor the size of the plant. It is nearly related to H. 

 rhodanthum, but is readily distinguished from it by its 

 canescent leaves, and stronger habit of growth.
