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 Kibes. Next to R. sanguineum, and its varie- 

 ties, thej' merit a place in every collection.

Spec. Char.jSfc. 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, 

 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. aureuni, 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 

 not more than half the size of R . aurcum ; and 

 have entire, not notched, petals. The fruit is 

 about the size of the red currant, of an agreeable 

 flavour but possessing little acidity. (IJon^s Mill.,
