Pruate LXXIV. 
HELIANTHEMUM ruperarta, Mill. 
Natural Order Cistinezx. 
Gen. Cuar.—Sepals 5, the two outermost smaller. Stamens many, all 
fertile. Ovules orthotropous. Style usually slender, incurved at apex, 
rarely wanting (as in H. tuberaria, Mill. and H. guttatum, Mill.). Ovules 
orthotropous, attached at the base. Capsule 1-celled, or incompletely 
d-celled. Seeds destitute of a raphe. 
Spec. Cuar.—lowers usually in a lax panicle, formed of two racemes, 
more rarely simple; buds nodding, flowers suberect when expanded ; 
bracts and upper stem-leaves glabrous, ovato-lanceolate acuminate. 
Calyx glabrous, of 5 ovato-lanceolate, and two outer linear sepals. 
Petals longer than calyx, truncato-flabelliform, yellow and without spots 
at their bases. Filaments of stamens yellow. Ovary densely clothed with 
stellate and simple hairs. Stigma sessile, capitate. Capsule shorter than 
the calyx by one-half. Leaves ovato- or elliptico-lanceolate, attenuate 
below into a petiole sheathing at base, densely clothed with long and. 
rather silky hairs, 3-nerved. Flowering stems ascending, developed on 
the lateral shoots, while the central shoct is barren, the rootstock, 
which is short and woody, bears the dead leaves of previous years, and is 
perennial.

Hasitat.—Behind the Hotel Bellevue, Cannes, where the specimens 
figured were gathered by the Rev. S. Henning, who kindly favoured me 
with them, April 30, 1871. 
Remarxs.—This plant has been described by some botanists as the 
type of a distinct genus, principally on account of its sessile stigma. 
Willkomm distinguishes three varieties of H. Tuberaria, Mill. which 
he names Tuberaria vulgaris—viz., 8. lanata, lower leaves, even when 
adult, clothed with long white hairs on either side. y. suffruticosa. 
Branches of rootstock 1-23 inches long, erect, almost 4-sided, blackish 
and covered with the bases of the old leaves, forming a low shrub 
(suffrutex). Leaves of the rosettes furnished with a petiole almost 
equalling the limb ; limb harsh, being covered above with small, sparse 
stellate hairs. Helianthemum lignosum, Sweet, t. 46 (figure taken from 
a remarkably luxuriant cultivated specimen). 0. alpestris. Rootstock 
perpendicular, thick, woody, branches short, forming a tuft resting
