July nnd August. It is one of the most desirable species of the genus, 

 being quite liardy, having flowers of the largest size, and thriving in almost 

 any soil or situation not too moist. Cuttings put in in autumn are soon 

 rooted, and the plant ripens seeds plentifully in ordinary seasons.

Spec. Char., Sfc. Leaves ovate-elliptical, acute, densely clothed with hoary

 of the Grand Canary Island, in elevated pine forests. This is a noble species, 

 growing to the height of 4 ft. and upwards, with fine po|)lar-like leaves, and 

 large pale rose-coloured flowers, with distinct petals, whicii appear in July 

 and August. It was introduced into the Botanic Garden at Chelsea in 

 1815, where it flowered soon afterwards, and plants existed there in 1825. 

 It forms a shrub, not sufficiently hardy to stand through the winter, about 

 London, in the open air, as a bush ; but, with dry litter laid about its roots, 

 and a slight covering of mats in the most severe weather, it may be pre- 

 served.
