350 ARBORETUM AND FRUTICETUM. PART III. 
Spec. Char., §c. Stem suffruticose, branched. Branches procumbent, densely 
tomentose. Leaves oblong-linear, with revolute margins, hoary-tomentose 
on both surfaces. Stipules narrow, linear, obtuse, longer than the petioles, 
and are, as well as the bracteas, tomentose and ciliated. Petals distinct, 
crenulated. (Don's. Mill., i. p. 313.) A native of England, producing its 
white flowers, marked with yellow, from May to August. It is found on 
stony hills near the sea side, particularly on Brent Downs, Somersetshire ; 
also at Babicome, near Newton Abbot, and on Tor Hill, near Torquay, 
Devonshire.

Varieties. There are three forms of this very handsome species; one with white flowers, another 
with smaller flowers of a rose red, and the third with double rose-coloured flowers. 
Spec. Char., §c. Stem suffruticose. Branches procumbent, rather tomentose. 
Leaves flat, ovate-oblong, acutish ; upper surface glabrous, under surface 
tomentose, pale-cinereous. Stipules rather pilose, generally equal in length 
with the footstalks of the leaves, or longer. Calyxes striated, smoothish. 
Petals imbricate. (Don’s Mill. i. p. 313.) A native of Spain, and in culti- 
vation in British gardens in 1829. The flowers are produced from June 
to August, in great abundance; and seeds are ripened afterwards in fine 
seasons. The plants are quite hardy. They were cultivated for sale in 
the Clapton Nursery in 1829. 
2. 86. H. varieca‘tum Swt. The variegated Helianthemum, or Sun Rose. 
Identification. Swt. Cist., t. 38.; Don’s Mill., 1. p. 314. 
Engraving. Swt. Cist., t. 38. 
Spec. Char., §c. Stem suffruticose, procumbent. Branches tomentose, rather 
hoary, diffusely procumbent. Leaves lanceolate, acute, flattish; under 
surface hoary-tomentose, upper surface green, rather scabrous. Stipules 
linear, ciliated, longer than the petioles. Calyxes covered with short vio- 
laceous tomentum. Petals imbricate, undulated. (Don’s Mill., i. p. 314.) 
A hybrid between H. rhodanthum and H. lineare, found by Mr. Sweet in 
the Chelsea Botanic Garden in 1827. ‘ When in full bloom, it makes a 
very pleasing appearance, from the diversity of colours in its flowers ; some 
being nearly all red, others variegated with dark and light red and white, 
and some altogether white: it also continues to bloom, if the weather prove 
favourable, from May to November.” It is as hardy as the indigenous 
species. 
»« 87. H. versi’coLtor Swit. The various-coloured Helianthemum, or 
Sun Rose.

Spec. Char., §c. Stem shrubby, erect. Branches ascending, rather hoary 
from stellate down. Leaves oblong, flat, or concave above; under surface 
hoary-tomentose, upper surface green, glabrous. Stipules oblong-linear, 
ciliated, bristly at the top, somewhat longer than the leaves. Calyxes 
covered with short tomentum. Petals imbricate. (Don’s Mill., i. p. 314.) 
A native of the south of Europe, and readily distinguished from H., varie- 
gitum by its upright habit of growth, and its lanceolate and acutely pointed 
leaves. The flowers are very variable in colour, scarcely two on the plant 
being alike; some are of a bright red, others nearly yellow, some copper- 
coloured, and others with a mixture of all these colours, and of the different 
shades between them; so that the plant, when in flower, has a curious va- 
riegated appearance. (Sweet.)
