Nomenclature of Spyridium parvifolium and S. obcordatum (Rhamnaceae: Pomaderreae) from southeastern Australia and Tasmania

The nomenclature and typifications of Spyridium parvifolium (Hook.) F.Muell. and S. obcordatum (Hook.f.) W.M.Curtis are reviewed. Spyridium parvifolium var. molle (Hook.f.) Benth., so far recognised as a separate taxon in Tasmania, is not accepted, following a recent molecular analysis of the species complex. Lectotypes are chosen for Cryptandra obcordata Hook.f. (basionym of Spyridium obcordatum) and its synonyms Trymalium serpyllaceum Reissek & F.Muell., as well as for Pomaderris parvifolia Hook. (basionym of S. parvifolium) and the synonyms Cryptandra mollis Hook.f., Trymalium eupatorioides Reissek & F.Muell., Trymalium hermannioides Reissek and Spyridium parvifolium var. hirsutissimum Benth.
