Lygodesmia grandiflora is recognized mainly by its relatively large corollas. Some variants were segregated as distinct species by A. S. Tomb; because of intermediates, putative hybrids, and associated identification problems, it is probably best to recognize these as varieties pending further investigation (A. Cronquist 1994; S. L. Welsh et al. 2003).
