tinged with a deep shade of blush on the outside. In our 
Glasgow Botanic Garden, and some other collections in 
Scotian, there is cultivated as the R. Cawcasicum, the ex- 
tremely beautiful variety here figured, than which I can 
conceive no plant more desirable or more ornamental for 
an American border or shrubbery. At this season (April, 
1835), notwithstanding a most unpropitious spring, our 
bushes, one of which is two feet high, and three feet in 
diameter, have the extremities of their fine leafy branches 
terminated with an umbel of large, beautiful, straw-coloured 
flowers, forming a striking contrast with the rich scarlet of 
other kinds of Ruopopenpron already beginning to show 
their blossoms in the same border. If the R. chrysanthum 
had been a common plant in our collections I should have 
thought our present one might have been an offspring from 
it and the true R. Caucasicum. 
Descr. A shrub, with spreading branches, amply clothed 
with leaves at their extremities, which are elliptical-lanceo- 
late, glabrous, dark-green above, minutely reticulated ; 
below rust-coloured from the presence of a copious, but 
extremely short, reddish-yellow down. Flowers in terminal 
umbels, or rather, if the pedicels were traced to the base, ra- 
cemes: but these pedicels are wholly concealed below by 
the large, membranous, concave, imbricated bractes, which 
form a cone-shaped covering to them, Pedicels and minute 
five-toothed calyx reddish, downy. Corolla large, straw- 
coloured, between campanulated and funnel-shaped, waved, 
slightly irregular within, on the upper side, marked with 
numerous fulvous spots. Style and stamens declined, the 
fatter longer than the corolla, and reddish ; the former 
shorter than the corolla, and of an uniform pale-yellow. 
Stigma capitate, yellow-green.
