    It always makes me smile to remember that nature ignores our attempts to precisely categorize everything. Thanks for this lovely illustration of one of my favorite genera.

    Kesera Anamthawat-Jonsson at the University of Iceland has published some interesting work on hybrids between dwarf birch B.nana (diploid) & downy birch B. pubescens (tetraploid). The hybrids are triploid with various fertility outcomes. The study was assisted by fluorescence imaging of the chromosomes. I think I understood the paper. Perhaps birch is prone to hybridisation, but if not, excuse this amateur.

    Regarding drawings as opposed photos, I still use drawings (Stella Ross-Craig) as an aid to identification & enjoyment of plant anatomy.
