ii. p. 751.) The four large, round, and smoothly clipped plants of phil- 

 Ijrea, on naked stems, mentioned in p. 45. as possessed by Evelyn at Says 

 Coiu-t, were doubtless of this species, and not of the genus Phillyrea, which 

 is of much slower and less robust growth. Tlie y/laternus was at that time, 

 and even so late as the time of Miller, frequently confounded with the Philly- 

 rea; but the two genera are readily distinguished by the position of their 

 leaves, which are alternate in i?hamnus, and opposite in Phillyrea. At pre- 

 sent, the alaternus is chiefly planted in town gardens, to conceal walls, and 

 because it is less injured by the smoke of coal than most other evergreens. 

 The species, and all the varieties, are readily propagated by cuttings, which are 

 taken off in autumn, and planted in sandy soil, in a shady border, and covered 

 with a hand-glass. Price, in the London nurseries, of the species, and of the 

 blotched-leaved variety, 9c/. a plant ; of the gold- and silver-edged-leaved, 

 2s. 6d. each : at BoUwyller, the species and varieties from 1 franc to 2 francs a 

 plant : at New York,?. As the roots are not very productive of fibres, when 

 large plants are chosen, they should be such as have been reared in pots, in 

 order that they may receive no check from removal.

 ii. p. 30.) A garden hybrid, a sub-evergreen shrub, raised from R. alpinus, 

 fecundated by R. .ilaternus, and forming a very distinct and desirable kind, 

 which, in British gardens, grows to the height of 10 ft. or 1 2 ft. The flowers 

 are green, and appear in May or June. There is a plant in the arboretum of 

 Messrs. Loddiges, which, in 1833, before it was cut down, was 8 ft. high. 

 There is one in the garden of the London Horticultural Society 5 ft. high.
