It is a conspicuous member of the very small and valuable group of winter-flowering shrubs. 7. Rhododcndron Ferrugineum.--Alps, 1752. Evergreen shrub 1 foot. Leaves oblong, of a shining green above, stellately dotted beneath. Flowers in corymbs, rose-coloured, funnel-shaped. It grows in profusion in the Alps, where it is called the Alpine Eose. 8. Rhododendron Ponticum.--Armenia, 1763. Evergreen shrub 10-12 feet. Leaves oblong-lanceolate, coriaceous, shining green above, rather rusty beneath.

The leaves are used as tobacco by the Indians. 2. Rhus Cotinus--S. Europe, 1656. Shrub 10-20 feet. Leaves obovate, smooth, stiff, on long footstalks, persistent until strong frosts. Flow...
