Herbarium: Medicinal Plants as Information

Broken base at main branch of A. alnifolia.

The sample is broken off in an uncontrolled, splintering fashion, demonstrating that even thin branches are wooden and rigid. A. alnifolia may grow in a tree-like or shorter shrub-like form in accordance to local conditions, growing larger in rich, gravel-heavy soils near streams. Grooves and knobs near the base of the branch show where twigs have broken off and healed.
