“…Absence of Paranephrops in the central West Coast repeats a familiar pattern in an area known to botanists as the "beech gap", which extends from about the Taramakau River south to the Mahitahi River, in recognition of its lack of southern beech forests (genus Nothofagus); forest in the region of the beech gap is entirely of podocarp/broadleaf composition (Wardle 1991;Leathwick 1998). Absence of beech is attributed to the residual effects of Pleistocene glaciation, combined with the slowness of beech forests to reinvade territory once glaciation ameliorated (Willett 1950;Wardle 1978).…”

New Zealand's two species of freshwater parastacid crayfishes have allopatric distributions, with one species in the North Island and northwestern South Island and the other in the eastern and southern South Island and Stewart Island. This gives the appearance of a vicariance event driven by uplift of the Southern Alps beginning in the Pliocene, and of former land connections across both Cook Strait and Foveaux Strait. However, separation of the two species may date from before the Southern Alps were formed. A diverse series of historical geological events is invoked to explain details of the distributions of these two species. Absence of Paranephrops from intermontane valleys of eastern flanks of the Southern Alps is notably different from patterns seen in freshwater fish species.

“…According to Garnock-Jones (1993 a), it forms a putatively monophyletic assemblage of approximately 150 species that range from eastern Australia and New Guinea to South America and the Falkland Islands. The greatest diversity is centred in New Zealand where the Hebe complex consists of several clearly defined lineages that were probably derived from an Australian progenitor (Raven 1973;Wardle 1978).…”

The Hebe complex comprises a putatively monophyletic group distributed from eastern Australia and New Guinea to the Falkland Islands. Analysis of ITS sequences supports five distinct clades within the complex, corresponding to Derwentia plus Hebe formosa, Heliohebe, Chionohebe plus Parahebe trifida, Parahebe, and Hebe. Hebe cheesemanii and Hebe cupressoides form a weakly supported Glade that is distinct from the Hebe Glade. Relationships of Hebe macrantha are poorly resolved. The currently recognised infrageneric classification of Hebe is not supported by this study, and the newly described genus Leonohebe Heads is considered polyphyletic. These results suggest that the progenitor of the Hebe complex originated in Australia. A rapid and extensive radiation followed establishment of a founder population in New Zealand. The combined effects of inbreeding, genetic drift, and strong selection on small populations fragmented by mountain-building and glaciation have contributed to its rapid evolution. At least two recent instances of long-distance dispersal be-B97045

“…Colour intensity of the corolla is apparently related to W light and/or temperature, but the types of pigments are presumably determined by genetic factors of the plant with respect to pollinators (Weiss 1995), although this may not apply to many New Zealand plants (see Wardle 1978).…”

Among the populations studied, the corolla, peduncle, foliage leaf, and bladders occasionally exhibited a reddish or purple pigmentation, apparently developed in a response to different environmental factors.Keywords Utricularia dichotoma; Lentibulariaceae; carnivorous plant; vegetative morphology; anthocyanins; stolon; traps; vegetation ecology; wetlands Abstract The occurrence of the carnivorous plant Utricularia dichotoma (including U. monanthos and U. novae-zelandiae) within different habitats throughout New Zealand was studied. Qualitative investigations on its ecology focused on plant sociological criteria and soil characters, including the qualitative amount of water and soil chemistry. A list of associated plant species is also provided. Results indicate that U. dichotoma prefers open wet habitats. Once established, however, it may grow in fertile and permanently submerged sites. The vegetative morphology of the species from different populations was also examined and correlated with ecological factors. Utricularia dichotoma basically consists of runner stolons, from each node of which arise various combinations of leaves, bladders (traps), and anchor and runner stolons. Plants of some populations also show simply branched, bladderbearing intermediate types of anchor and runner stolons (designated "simple stolons"). Some nodes of runner stolons support the development of a peduncle. In the populations studied, the onset of a dry sunny period was typically followed by flowering. Plants from Kopouatai Peat Dome exhibited certain distinctive morphological features not found in other populations, including more bladders per plant. B98046
