This species is variable in habit, size of leaflets and indumentum. Several specimens previously identified as L. suaveolens and L. hispidus have been redetermined by D. Sokoloff as L. subbiflorus. We are tentatively assuming that all NSW material of these species will, in fact, belong to L. subbiforus.
