Salix, a large genus, the native species numerous and mostly shrubs, frequently 

 exhibiting polyploidy and hybridizing freely, producing progeny often difficult or 

 impossible to identify with certainty, such hybrids often persisting and spreading 

 vegetatively and in some cases reproducing apomictically ; the principal local group 

 of woody plants to persist and spread in river-gravels. 



S. nigra Marsh. Black Willow.
