A shrub, from the north of Portugal, growing to 
the height of 3 ft.; cultivated in British gardens 
since 1775; and producing its fine yellow flowers 
from June to August. It forms a handsome little

of it were in the Bristol Nursery in 1827.

Spee. Char., §c. Stem branched. Leaves sessile, ovate-lanceolate, obtuse ; 
hoary on the under surface; upper surface green, pilose. Peduncles some- 
what panicled, pilose. Calyx 3-sepaled, acute, hairy. (Don’s Mill., i. p. 
302.) A shrub 3 ft. high, found in Portugal, in the Algarves ; introduced 
into England in 1800; and producing its fine deep-yellow flowers from 
June to August. The petals are crenated, with a dark base, similar in 
colour to those of Callidpsis bicolor. According to Sweet, this species is 
nearly allied to H. ocymoides. It is rather tender, and requires protection 
during winter. Plants of it, at 1s. 6d. each, may be obtained in all the 
London nurseries.

Spec. Char., §c. Erect. Branches tomentosely villous, canescent. Leaves 
on short footstalks, obovate-lanceolate, tomentosely villous, younger ones 
hoary. Peduncles and calyxes villous. Calyx 3-sepaled. (Don’s Mill., 
i. p. 302.) A shrub growing to the height of 4 ft., introduced in 1780, and 
producing its fine large flowers, with yellow dark-spotted petals, from May 
to July. The stem is erect and much branched, the leaves lanceolate and 
3-nerved, and the flowers the largest of the genus. It is a most desirable 
plant to keep in pots, and turn out into borders in the spring; or, by keep- 
ing it against a wall and protecting it with mats, it will produce a fine show
