''Acacia pubescens'', also known as the downy wattle, is an endangered wattle found in the Sydney Basin in central New South Wales. Much of its habitat has vanished with the growth of the city of Sydney. ==Taxonomy== French botanist Étienne Pierre Ventenat described the downy wattle in 1803, in his ''Jardin de la Malmaison'' as ''Mimosa pubescens''. It had been grown at the Château de Malmaison in the garden of the Empress Joséphine de Beauharnais. Robert Brown gave it its current name in 1813 in ''Hortus Kewensis''. Common names include downy wattle and hairy-stemmed wattle.〔 Derived from the Latin ''pubescens'' "hairy", the species name relates to the hairy stems. Along with other bipinnate wattles, it is classified in the section ''Botrycephalae'' within the subgenus ''Phyllodineae'' in the genus ''Acacia''. An analysis of genomic and chloroplast DNA along with morphological characters found that the section is polyphyletic, though the close relationships of it and many other species were unable to be resolved. Hybrids with Cootamundra wattle (''Acacia baileyana'') and West Wyalong wattle (''A. cardiophylla'') have been reported.〔
