2. 95. H. cu‘preum Swt. The copper-colour-flowered Helianthemum, or 
Sun Rose.

Engraving. Swt. Cist., t. 66. 
Spec. Char., §c. Stem suffruticose, procumbent. Branches ascending, rather 
' tomentose; adult ones glabrous. Leaves oblong-lanceolate, channeled; upper 
surface green, hairy; under surface hoary-tomentose. - Stipules lanceolate, 
acute, ciliated, bristly at the apex, twice as long as the footstalks of the 
leaves. Calyxes tomentosely pilose. Petals imbricated. (Don’s Mill. i. 
p- 314.) A hybrid, found by Mr. Sweet in the Hammersmith Nursery in 
1827. The petals are of a dark copper colour, with a darker mark at the 
base of each. The flowers appear from May to August, and the plant re- 
quires very little protection. 
& 96. H. venu’stum Swt. The handsome Helianthemum, or Sun Rose. 
Identification. Swt. Cist., t. 10.; Don’s Mill., 1. p. 314. 
Engraving. Swt. Cist., t. 10. 
Spec. Char., §c. Stem suffruticose, ascending, branched. Branches glabrous, 
warted, somewhat tomentose at the apex. Leaves oblong-lanceolate, acute, 
flat, or hardly revolute in the margins, but denticulately scabrous; under 
surface hoary-tomentose, upper surface green, shining. Stipules Janceolate, 
hairy, ciliated, twice as long as the footstalks of the leaves. Inner sepals 
membranous, with hairy warted nerves. Petals imbricated. (Don’s Mill, 
i. p. 314.) The native country of this beautiful plant is not known, though 
it is now very common in collections about London. It is very suitable for 
rockwork, as it is quite hardy, and continues in flower during the whole 
summer. In some collections, Sweet tells us, it is considered only as a 
variety of H. vulgare; but he says that it is more nearly allied to H. 
rhodanthum ; from which, however, it may be easily distinguished “ by its 
warted stalks and calyxes, and its smooth shining stems.” It was in Col- 
vill’s Nursery in 1825.

Engraving. Swt. Cist., t. 101. 
Spec. Char. Stem suffruticose, procumbent. Branches _hairy-tomentose. 
Leaves oblong, bluntish, flat, green on both surfaces, hairy. Stipules falcate, 
longer than the petioles. Calyxes hairy. Petals imbricate. (Don’s Mill., i. 
p- 315.) A hybrid, with saffron-coloured flowers, with a dark mark at the base 
of each petal. It is nearly related to H. hyssopifolium, from which it differs 
in its dull green and rough leaves, which are much more hairy. It is also 
related to H. nummularium, and may, probably, be a hybrid between the two. 
It is one of the most ornamental sorts of the section to which it belongs, 
and is so hardy as to require no protection in winter. Plants of it were in 
the Bristol Nursery in 1829.
