A Note on Aggregate Rays of Betula Species
1983
Bhat, K.M.
Observations were made on the presence of aggregate rays in four birch species: Betula pendula Roth, B. pubescens Ehrh., B. tortuosa Ledeb. and B. nana L. Aggregate rays rarely occur in Betula; however, when present, their occurrence is probably due to insect injuries (pith flecks) and branch traces.
