Alnus glutinosa (L.) Gaertn.
Alnus glutinosa
A medium-sized, short-lived tree growing up to 30 meters. Thrives in wet locations and has a symbiotic relationship with the bacterium Frankia alni, which allows it to grow in poor-quality soils. It has short-stalked rounded leaves and separate male and female flowers in the form of catkins. The small, rounded fruits are cone-like and seeds are dispersed by wind and water.

The chemistry of Alnus glutinosa includes hirsutanonol, oregonin, genkwanin, rhododendrin {3-(4-hydroxyphenyl)-l-methylpropyl-β-D-glucopyranoside}, and (penta-2,3-dienedioic acid). The bark contains 16 to 20% tannic acid.
The common alder provides food and shelter for wildlife, including a number of insects, lichens, and fungi that are completely dependent on the tree. It is used in ethnobotany for various folk remedies, including astringents, cathartics, hemostatics, febrifuges, tonics, and restoratives. Extracts of the seeds are active against pathogenic bacteria, including Escherichia coli and methicillin-resistant Staphylococcus aureus (MRSA). The wood is used for paper-making, manufacture of fiberboard, production of energy, and as a tonewood in electric guitars. The bark is used in tanning and dyeing.
