VARIATION IN EUCALYPTUS BARBERIL. JOHNSON & BLAXELL

Phenetic variation within Eum(vptlls barberi L Johnson & Bb.xdl was examined and compared to related Tasmanian species. "Typical" northern populations were morphologically distincr {"rom tbe more diverse group oEpopulations to the south. This phenetic disjunction did not correspond ro the major geographic disjunction in the range of E. barberi. Derailed study of tWO morphologically aberrant populations indicated that they pl'Obably arose from in situ hybridisation; however, the exact identities of the progenitor species remains unclear. The type locality and several of tbe "southern" populations, as well as aberrant populations at Meredith Tier and Ponybonol11 Creek, deserve formal conservation.
