990 ARBORETUM AND FRUTICETUM. PART III. 
This, and the preceding varieties, are highly ornamental, from their 
fine, large, bright yellow flowers, which are produced in abundance ; 
and their smooth, glossy, yellowish green leaves. The plants are, 
also, most truly ligneous, and of greater duration, than those of 
most other species of bes. Next to R. sanguineum, and its varie- 
ties, they merit a place in every collection.

Engravings. Bot. Reg., t. 1274.; and our fig. 744, 
Spec. Char.,§c. Unarmed, quite glabrous. Leaves roundish, 3-lobed, mealy ; 
lobes bluntly toothed at the apex. Racemes pendulous, many-flowered. 
Calyx tubular, glabrous, longer than the pedicels, 44: AY 
coloured. Petals quite entire, linear, one half 
shorter than the segments of the calyx, which 
are oblong and obtuse. Bracteas linear, length 
of the pedicels. Berries glabrous. In _ habit, 
this species is more erect than R. ajreum, and 
has the young wood more thinly clothed with 
leaves ; its whole appearance is also paler, during 
the early part of the season. The flowers are Q.g¥ 
not more than half the size of R,atreum; and & ™ 
have entire, not notched, petals. The fruit is 
about the size of the red currant, of an agreeable 
flavour but possessing little acidity. (Don’s Mild,
