CISTACE.E. 11 



3 to G indies long:. Leaves ^ to 11 inch long, very varuilfle iii 

 sliape. Stipules generally considerably longer than the petiole. 

 Flowers f to Ij inch across, in a unilateral raceme. Bi'acts narrow. 

 Fruiting pedicels reflexed, about as long as the sepals. Leaves 

 giMierally green above and white below, though a variety occurs 

 which is green on both sides ; but no British specimens of this have 

 come under my notice. Stem and pedicels more or less thicklv 

 clothed with hairs. H. tomentosum is scarcely separable even as 

 a variety. H. surrejanum (Eng. Bot. No. 2:207) is a garden variety 

 or monstrosity of U. vulgai-e.

The havdy species of tliis jiretty genus of plants are among the most beautiful 

 little shrubs for ornamenting rock-work, and deserve cultivation on account of the 

 elegance and various hues of their blossoms.

 Cistus po'ifolius, Linn. Sni. Eng. Bot. No. 1322. 



Root perennial. Stems shrubby, procumbent, much branched. 

 Leaves opposite, shortly stalked, elliptical, oblong or strap-shaped, 

 \vith the edges more or less revolute, clothed with a dense felt of 

 grey stellate pubescence beneath and a thinner one above, with scat- 

 tered white hairs on the margins and on the midrib beneath ; stipules 

 linear. The three inner sepals thrice as long as the two outer ones, 

 oval, obtuse, not apiculate, thickly clothed with stellate pubescence, 

 with distinct ribs destitute of long hairs and no black dots. Petals 

 much longer than the sepals, white with a yellowish claw. 



On barren stony places. Very rare. Babbicombe and Torquay 

 in Devonshii-e, and Brean Down, Somersetshire. 



England. Shrub. Early Summer. 



Very like II. vulgave but more wiry, the flowering shoots 

 more Avoody and erect, the whole plant more densely clothed with 

 pubescence, which Avith the white flowers and revolute-cdged leaves 

 render it easily distinguishable from that species. 



The British plant is IE. pulvernlentum of De Candolle and Con- 

 tinental authors. 11. Apenninum, D. C, is a variety, or perhaps a 

 sub-species, with the leaves less revolute and, consequently, broader, 

 greener above, and with the calyx less thickly clothed with stellate 

 ■ down.
