Paakspuu (Paakspuu)

Aka harilik paakspuu, aka mõruuibu (bitter apple-tree, where uibu is probably a shortening of ubinapuu, an older/dialect term for apple-tree, see Õuna and Puu). Commonly known as alder, glossy or breaking buckthorn, black dogwood, Frangula alnus (aka Rhamnus frangula). Having said that, trees are often hard to identify exactly and the term paakspuu may also refer to the black alder (Alnus glutinosa), which micht explain the paak (seamark or beacon), due to its durability under water (same wood used as pilings in [under] Venice, see Paali). Tree/shrub group, see Lõhmuse põik and Pukspuu.
