Salix ×sepulcralisnothovar. chrysocoma (S. albavar. vitellina × S. babylonica) is very widely planted for ornament and stream stabilization in southeastern Australia and is commonly naturalized. It was formerly identified with S. babylonicaby Australian authors and frequently occurs with that species, sometimes as the more abundant taxon. Reproduction is mostly vegetative, but seed is set in Victoria. While generally distinctive in twig coloration, specimens are not always positively identifiable; it is likely to be connected with other weeping willow taxa by intermediates.
A weeping willow commonly naturalized along the lower Mitchell River resembles nothovar. chrysocomabut trees are of unusually low stature and have slightly flexuose branches and twigs; it may be related to S. ×sepulcralis‘Erythroflexuosa’ (S. matsudana‘Tortuosa’ × S. sepulcralisnothovar. chrysocoma) but lacks the contorted leaves of that taxon. Further study is required.
