<meta content="The variation in selected leaf morphological traits was examined across the geographic ranges of two Tasmanian rainforest species, Tasmannia lanceolata (Poiret) A.C.Smith and Eucryphia milliganii Hook.f. Comparisons of field- and glasshouse-grown plants for both species showed that there is strong genetic control of all the morphological characters measured. Two distinct morphotypes, occupying similar areas of Tasmania, were identified in each species. The geographic boundary between the morphotypes is similar in both species and runs more or less east-west, separating each species into northern and southern forms. Southern E. milliganii differs from the northern form in having ovate leaves with dense marginal trichomes and a pubescent abaxial leaf lamina. A new sub-species, E. milliganii ssp. pubescens, is described to encompass this intra-specific variation in southern Tasmania. Southern T. lanceolata has encrypted stomata, contrasting with the superficial stomata of the northern form, but is not considered sufficiently different to warrant separate taxonomic status. The boundary is difficult to explain in terms of modern environmental factors. A past period of significantly different climate from the present, perhaps combined with anthropogenic fire regimes, may have enabled allopatric differentiation within each species." name="eprints.abstract" />

Comparisons of field- and glasshouse-grown plants for both species showed that there is strong genetic control of all the morphological characters measured. Two distinct morphotypes, occupying similar areas of Tasmania, were identified in each species. The geographic boundary between the morphotypes is similar in both species and runs more or less east-west, separating each species into northern and southern forms. Southern E. milliganii differs from the northern form in having ovate leaves with dense marginal trichomes and a pubescent abaxial leaf lamina. A new sub-species, E. milliganii ssp. pubescens, is described to encompass this intra-specific variation in southern Tasmania. Southern T. lanceolata has encrypted stomata, contrasting with the superficial stomata of the northern form, but is not considered sufficiently different to warrant separate taxonomic status. The boundary is difficult to explain in terms of modern environmental factors. A past period of significantly different climate from the present, perhaps combined with anthropogenic fire regimes, may have enabled allopatric differentiation within each species.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available online at http://www.publish.csiro.au/nid/65.htm</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">biogeography, quaternary, paleaoclimate</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/270401.html">270000 Biological Sciences > 270400 Botany > 270401 Plant Systematics, Taxonomy and Phylogeny</a><br /><a href="http://eprints.utas.edu.au/view/subjects/270709.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270709 Biogeography</a></td></tr><tr><th valign="top" class="ep_row">Collections:</th><td valign="top" class="ep_row">UNSPECIFIED</td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1798</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">dr gregory j jordan</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">03 Sep 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">11 Feb 2008 11:00</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=1798;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&eprintid=1798">item control page</a></p>
