and seeds. The seeds should be sown, and the seedlings after- 
wards managed in the manner recommended for Rhododéndron;

—The species of Vaccinium are mostly confined to Europe and 
North America, but are peculiarly abundant in the latter country. 
They are suffruticose, shrubby, gemmaceous plants. Bud-scales 
often permanent, on the base of the small branches. Leaves alter- 
nate, membranous, often beset with resinous dots, either permanent 
ordeciduous. Flowers pedicellate, either solitary, simply racemose, 
or tufted, drooping, inodorous, generally very elegant, tinted with 
various shades of red or pink, never blue, scarcely yellowish.
