ox TREES AND SHRUBS. 



U. m. vars. macrophylla^ atropiirpiirea^ lad?iiafa, and cinerea 

 are by no means so well known as they deserve to be. 

 U. alata is a green-leaved kind with distinct cork-like bark. It 

 rarely exceeds 35ft. in Iieight. 



Vacciniums are useful shrubs and very free-flowering. Those 

 here mentioned are quite hardy and delight in peaty soil.

V. corymbosum (Swamp Blueberry) often grows about 7ft. high, and 

 carries dense clusters of pale pink flowers in May and June on 

 the previous year's wood. V. peiinslyvaniciim (Dwarf Blueberry) 

 is a showy, low, much-branched autumnal - tinted shrub bush, 

 with racemes of pale rose-coloured flowers, succeeded by sweet 

 bluish-black berries. V. iiliginosuni and V. stamineum are also 

 noteworthy.
