Abstract:
... Leptospermum repo de Lange & L.M.H.Schmid sp. nov. (Myrtaceae) is segregated from L. scoparium J.R.Forst. & G.Forst. (sensu lato). The new species is endemic to the peat bogs of the Waikato, Bay of Plenty, and adjacent eastern ranges of the northern portion of Te Ika a Maui / North Island, Aotearoa / New Zealand. The new species belongs to the northern Te Ika a Maui / North Island clade of L. scop ...

Abstract:
... A molecular phylogeny to test the monophyly of Nephelolejeunea by using previously published nrITS, rbcL and trnL–F sequence data demonstrated that Nephelolejeunea is paraphyletic with respect to Siphonolejeunea. Nephelolejeunea and Siphonolejeunea are, therefore, merged and, as the latter name has priority, new combinations in Siphonolejeunea are made for 10 species. The valid publication of the ...

Abstract:
... Kunzea (Myrtaceae) trees and shrubs, generally called kānuka, grow across most of Aotearoa/New Zealand (NZ). With the exception of K. sinclairii, an offshore island endemic, kānuka had been treated as an Australasian species K. ericoides. However, a 2014 taxonomic revision recognized ten species, all endemic to NZ. Kānuka chemistry is less studied than that of its closest relative in NZ, mānuka (L ...

Abstract:
... As presently delimited, the endemic New Zealand species Senecio glaucophyllus Cheeseman shows considerable morphological and ecological diversity. Two morphologically similar forms associated with this taxon are found in northwest Nelson (South Island), of which one is often filed in herbaria as S. glaucophyllus subsp. glaucophyllus. The other form has been informally recognised as S. aff. glaucop ...

Abstract:
... A rational taxonomic circumscription of genera in tribe Anemoneae (Ranunculaceae) is briefly discussed. It is concluded that, in view of the morphological diversity of the group and recent molecular phylogenetic findings, a moderately narrow approach to the re-circumscription of genera earlier included in Anemone sensu lato is preferable, in particular, with the recognition of the lineage with the ...

Based on recent collections from northern North Island, we describe a fifth species Ocellularia jacinda-arderniae, which is a member of the O. bicuspidata complex. This complex is characterised by peculiar, appendiculate ascospores and a psoromic acid chemistry. Two furthe ...

Abstract:

The distribution of whau in the southern North Island and South Island has been suggested to result from pre-European Māori cultivation. Whau wood is extremely buoyant and was used to make fishing floats and rafts. We sequenced two chloroplast loci and the nuclear ITS region ...

This non-monophyletic group of early diverging clades in the genus Sticta is characterized by a stalked thallus with a green primary photobiont and the frequent formation of a dendriscocauloid cyanomorph. Traditionally, three species have been distinguished in New Zealand: S. filix (Sw.) Nyl., S. lacera (Hook. f. & T ...

Our main objective was to examine the phylogeographic distribution of chloroplast DNA from New Zealand Sophora trees with respect to known biogeographical regions, proposed refugia and species boundaries. A second objective was to investigate the origins of the sou ...

Because of its remoteness and mid-latitude position, New Zealand lacks access to the tropical climates that might have ensured straightforward survival for frost-sensitive species during glacial times. Nevertheless, the New Zealand lowland flora retains a substantial complement of plants sourced in the tropics. While there have been extinction pulses for elements of the frost-sensitive flora under ...
