distinct at the base. (Don’s Mill., i. p. 314.) A hybrid, found in Colvill’s 
Nursery, Chelsea, in 1828. It is nearly related to H. sulphureum, but 
differs from it in habit, and in having a woolly calyx. The leaves are narrow, 
and undulated in the margins. :

Variety. 
a H. rv. 2 miltiplex. (Swt. Cist., 86.) — A very pretty double variety : itis well suited to rock- 
work, on which it grows vigorously,;and produces large flowers. It is quite hardy, and 
continues in bloom the whole summer. 
Spec. Char., §c. Stem suffruticose, rather procumbent, somewhat tomentose. 
Leaves ovate-lanceolate, tomentose on the under surface, green above, 
hairy. Stipules lanceolate-linear, ciliated. Pedicels and calyxes pilosely 
hairy. (Don’s Mill., i. p. 314.) A native of the south of Europe, and very 
nearly allied to H. vulgare. The petals are rose-coloured, and imbricate at 
the base. It flowers in June and July, and was introduced in 1815. It is 
a very pretty plant, from the delicate colour of its flowers; and it is very 
suitable for rockwork, as it will continue in bloom for several months. It 
requires protection during frosts. It was cultivated in the Fulham Nursery 
in 1827.

Spec. Char., &c. Stem suffruticose, procumbent, pilosely hairy. Leaves oblong, green on both sur- 
faces, hairy, roughish. Stipules hairy, linear, longer than the footstalks of the leaves, Pedicels 
and calyx rather hairy. (Don’s Miil.,i. p. 314.) A hybrid, resembling H. vulgare, but differing 
from it in having white flowers. The whole plant is said to smell like Brydnia. It :produees its 
flowers from May to July, and was in cultivation in 1800.

Varieties. 
2. H.h. 1 crocatum (Swt. Cist., t. 92.) has flowers saffron-coloured, with 
more or less, of a ferrugineous tint, and may represent the species. 
Plants of it were in the Clapton Nursery in 1828, 
2. H. h. 2 cupreum (Swt. Cist., t. 58.) has flowers of a reddish copper- 
colour. Plants of it were in the Fulham Nursery in 1827. 
2 H.h. 3 miltipler (Sut. Cist., t.72., and our 
Jig. 75.) has double flowers, of a reddish 
‘ copper-colour. Plants of this variety were 
in the Fulham Nursery in 1828. 
Description, §c. All the three forms of this species _ 
are splendid plants; they are hardy, of luxuriant ¥ 
growth, flowering freely, and of the easiest culture, % 
either in pots or on banks of light sandy soil, covered 
with flints or stones. The flowers of the copper- 
coloured variety, and also the leaves, are larger than 
those of the two other kinds. The double-fowered 
variety appears to be of a more upright habit of 
growth, and not quite so robust as the others. Sweet 
says that he is “ acquainted with two other very 
distinct. varieties; one with flowers of a lighter 
colour, and the other having double flowers.”
