jV I r . EDWARD DU BOIS discovered this curious species in
the neighbourhood of Croydon, Surrey, in the time of Dil-
lenius, who first made it known to the botanical world in his
edition of Ray, and then in the Hortus Elthamensis. We
know not where it is now to be met with wild, nor has it ever
been noticed in other countries. Our specimen grew in .Mr.
Dickson’ s garden at Croydon, flowering in July.
Though the plant never varies in consequence of culture,
some qf the above circumstances might induce a suspicion of
its being only a variety of C. Helianthemum, t. 1321; but the
leaves are larger, more inclined to a lanceolate than an elliptical
figure, paler but not at all hoary beneath. The under
surface bears a few stellated hairs, and is besprinkled with
little hollows, which on the upper side form prominences that
often bear 2 or 3 simple, not stellated, bristles. Flowers numerous,
in long, terminal, recurved, downy clusters; each
flower erect when in perfection. Calyx with red ribs. Petals
narrow, lanceolate, oblique, often toothed, acute, usually
rather longer than the calyx. Stamens scarcely longer than
the germen, not, as in C. Helianthemum, equal to the petals.
