Similar to Acacia conferta which is usually less hairy and has longer, thinner and less pubescent peduncles. The name 'mariae' honours Dr Mary Douglas Tindale (1920-2011), formerly a botanist with the National Herbarium of New South Wales, where she specialised in acacias and ferns. The wattle originally honouring Dr Tindale is Acacia tindaleae, but the Type specimen with that name has been found to be a minor variant of A. conferta. This makes A. tindaleae a synonym of A. conferta, however, plants from New South Wales to which the name is usually applied (as in Kodela & Harden 2002) represent a distinct species, A. mariae (see Pedley 2006). Therefore, although the name A. tindaleae is now under A. conferta, most specimens formerly identified as A. tindaleae are A. mariae. Also, the treatment of A. tindaleae in the Flora of NSW Volume 2 (2002) applies mostly to A. mariae. An attractive hybrid, Acacia mariae x semilunata, was found in a nursery and since cultivated at Mount Annan Botanic Garden.
