CHAP, XI. CISTA‘CEX. HELIA NTHEMUM. 347 
Spec. Char., §c. Stem suffruticose, branched. Branches erectish. Leaves 
linear or linear-oblong, hoary on both surfaces, and bristly at the apex. 
Stipules awl-shaped. Calyxes rather pilose, nervously striated. (Don’s 
Mill., i. p. 312.) A native of Spain and the south of France, and in cul- 
tivation since 1731; producing its white flowers from May to July. Ac- 
cording to Sweet, it is nearly related to H. lineare, and also to H. apenninum: 
but it differs from the former in having whiter leaves, and being more hairy ; 
and from both, by its imbricate paper-white petals. Plants of it were in the 
Fulham Nursery in 1826.

Spec. Char., §c. Stem suffruticose. Branches elongated, ascendent, rather 
hoary, tomentose. Leaves linear, greenish hoary, with revolute margins. 
Stipules linear awl-shaped. Racemes loose, twiggy, few-flowered. Calyxes 
striated, glabrous, with the nerves somewhat violaceous. Sepals acute. 
(Don’s Mill., i. p. 312.) A native of Spain and the south of France; in 
cultivation since 1817; and producing white flowers from June to August. 
It requires a little protection during winter. 
#2 75. H. virca‘tum Pers. The twiggy Helianthemum, or Sun Rose. 
Identification. Pers. Ench., p. 79.; Don’s Mill., 1. p. 313. 
Varieties. De Candolle mentions two forms of this species: H .v. albiflorum, in which the petals are 
white; and H/. v. rdseum, in which they are pale rose-coloured. 
Spec. Char., §c. Stem suftruticose, with twiggy, hoary, ascending or erect 
branches. Leaves linear, hoary on the under surface, with revolute mar- 
gins. Stipules linear awl-shaped. Calyxes hoary, powdery, pubescent. 
(Don's Mill., i. p. 313.) A native of Barbary, and in cultivation since 1818. 
The flowers are of a pale rose colour, large in proportion to the leaves, and 
the petals have yellow spots at the base. The flowers appear from May to 
August. This is one of the most beautiful species of the section to which 
it belongs : it requires a little protection during winter, but grows and 
flowers freely during summer, and also ripens seeds. Plants of it were in 
the Epsom Nursery in 1828.

Varieties. De Candolle records two forms of this species ; one with leaves broad and flattish, andt 
other with leaves linear and narrow. 
Spec. Char., §c. Stem suffruticose, branched. Branches spreading, hoary 
tomentose. Leaves stalked, oblong linear, with the margins scarcely revo- 
lute; under surface tomentose, upper surface glaucescent, but at length 
becoming smooth. Stipules awl-shaped, longer than the footstalks of the 
leaves. Calyxes covered with very short hairs, striated, cinereously glaucous, 
bluntish. (Don’s Mill., i. p. 313.) A native of Spain, France, Italy, and 
Germany, on dry hills and places exposed to the sun; and in cultivation in 
British gardens since 1731. The flowers are white, and the petals are 
distinct, and marked with yellow at their base. The plant is as hardy as 
the common species. It was in the Chelsea Botanic Garden in 1828,
