LI. LE'DUM (XrjcW, ledon, was a name applied by the

LIN. SYST. Octo-Decdndria, Monogynia. Calyx 4-5-toothed 

 (f. 142. a.) Corolla urceolate or campanulate (f. 142. 6.), more or 

 less deeply 4-5-cleft ; limb reflexed. Stamens 8-1 0, hypogynous.

 (f. 142. e.), depressed at top, 4-5-celled (f. 142./.), many-seeded.

 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 

 or deciduous. 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.
