Pheneric variation within Eum(vpt11s barberi l.. Johnson & Bb.xdl was examined and compared to related Tasmanian species. "Typical" northern populations were morphologically distincr from the more diverse group of populations to the south. This phenetic disjunction did not correspond rn the major geographic disjunction in the range of E. barheri. Di:railed study of rwo morphologically aberrant populations indicati:d that thi:y probably arose from ;,, situ hybridisation; however, the exact identities of the progenitor species remains unclear. The type locality and several of tbc •'southern" populations, as wdl as abi:rra nr populations at Meredith Tier and Ponybottom Crci:k, deser v e formal conservation.
