m. An ALDER- tree, called ELLER and ALLER ; alnus; alnus glutihosa, Lin. The alder, or rather aler, is an inhabitant of swamps and meadows in all Europe, the north of Africa and Asia, and North America. Its favourite station is by the side of rivulets, or in the elevated parts of marshy land where the soil is drained. Its juice contains a great abundance of tannin, which renders the bark valuable for tanning, and the young shoots for dyeing. Its foliage being large, and of a deep handsome green, the alder is rather an ornamental tree. The alder alnus glutinosa must not be confused with the elder sambucus nigra the elder-tree, except alder, L. M. 1, 36; Lchdm, ii. 86, 9. On ðone [MS. ðane] alr to the alder, Cod. Dipl.
