Sookaskede (Sookased [pl.])

Sing.: sookask aka karune kask (hairy birch), sokikask (although this reads like ‘sock’ birch, Wiedemann gives it as a genitive of sokk:soki ‘juice’, i.e. the sap that locals drink [see Mähe], I mean, the buggers don’t just stop at hugging trees…), sookõiv (marsh birch), suukõiv (‘mouth’ birch, but poss. a dialect form of soo), downy, white, European white or hairy birch, Betula pubescens, presumably the one that younger Estonians use to flagellate themselves in the sauna.
