This study revises an expanded Carex section Inversae for New
Zealand. Eleven indigenous species are recognised, 10 of which
are endemic. Notable features are the presence of unisexual
spikes associated with gynodioecious and dioecious sexual
systems, androgyny, and diandry. Based on results from
morphometric analyses of Carex kirkii s.l., C....
In New Zealand, Craspedia (Compositae/Asteraceae, Gnaphalieae) has much more morphological variation than previously recognised, as demonstrated by suggestions of about 50 informally named putative species and varieties. As part of our research towards a revision of New Zealand Craspedia we have focused here on those plants that can be segregated f...
Carex subgenus Psyllophorae is an engaging study group due to its early diversification compared to most Carex lineages, and its remarkable disjunct distribution in four continents corresponding to three independent sections: sect. Psyllophorae in Western Palearctic, sect. Schoenoxiphium in Afrotropical region, and sect. Junciformes in South Americ...
Archer’s sedge (Carex archeri Boott) is a small, rare (or possibly overlooked by collectors due to the diminutive size) species restricted to alpine and subalpine habitats in south-eastern mainland Australia and Tasmania. The systematic placement has been obscure with the species having been historically associated with sections in four of the six...
This publication is a record of the gymnosperms and flowering plants present in New Zealand based on specimens held in the Allan Herbarium (CHR) and the names that institution prefers to use for them.
Our research towards a revision of New Zealand Craspedia (Compositae/Asteraceae, Gnaphalieae) led to the recognition of a new species from Nelson/Tasman, South Island of New Zealand. Craspedia huriawa occurs only in the area of the Riuwaka River North Branch at the base of Tākaka Hill, Pikikirunga Range. It is morphologically similar to C. minor bu...
Simple Summary
The evolution of the flora of New Zealand has been the subject of many debates, including trans-oceanic dispersal and vicariance. Deschampsia, which is a grass genus distributed in cold–temperate regions of both hemispheres, includes the cosmopolitan D. cespitosa and several endemic species in New Zealand. We applied Restriction Site...
Pseudomonomerous gynoecia with three (or four) carpels are unknown in the species-rich core group of Apiales, but this condition is shared by three species-poor families (Pennantiaceae, Torricelliaceae, Griseliniaceae) that form the basal grade of the order. Testing a hypothesis on the ancestral nature of carpel dimorphism in Apiales requires compa...

Phylogenetic studies of Carex L. (Cyperaceae) have consistently demonstrated that most subgenera and sections are para‐ or polyphyletic. Yet taxonomists continue to use subgenera and sections in Carex classification. Why? The Global Carex Group here takes the position that the historical and continued use of subgenera and sections serves to (1) org...
The water-plantains are an aquatic and semi-aquatic family of about 113 species of herbs in 17 genera (Les & Tippery 2013) with a near cosmopolitan distribution. The Alismataceae are represented in New
Zealand by three genera, Alisma, Hydrocleys and Sagittaria, and seven species, all of which are naturalised. Three species of Sagittaria and Hydrocl...

The megadiverse genus Carex (c. 2000 species, Cyperaceae) has a nearly cosmopolitan distribution, displaying
an inverted latitudinal richness gradient with higher species diversity in cold‐temperate areas of the Northern
Hemisphere. Despite great expansion in our knowledge of the phylogenetic history of the genus and many molecular
studies focusing...

While examining herbarium specimens of Trithuria inconspicua Cheeseman, we observed differences in the stigmatic hairs among plants from New Zealand’s North and South Islands. This motivated us to assess genetic and morphological variation within this species and its sister T. filamentosa Rodway from Tasmania. Samples were collected from lakes in t...
The Nymphaeales contains three plant families, Cabombaceae, Hydatellaceae and Nymphaeaceae, and is the most species-rich order of the early diverging angiosperms known as the ANA grade (Amborellales, Nymphaeales, Austrobaileyales). All three families are represented in New Zealand. Hydatellaceae is represented by only one species, the indigenous Tr...

The conservation status of all known New Zealand indigenous vascular plant taxa (as of
September 2017) was reassessed using the New Zealand Threat Classification System (NZTCS). A full list is presented, along with a statistical summary and brief notes on the most important changes and nomenclature. This list replaces all previous NZTCS lists for v...
The scientific names of plants “provide a means of reference to facilitate communication about those
organisms” (Turland 2013). Established over 300 years ago, the process of naming plants is today governed
by the International Code of Nomenclature with the names themselves anchored by a type specimen. In this
electronic age the names remain a vita...
We present the first large-scale phylogenetic hypothesis for the genus Carex based on 996 of the 1983 accepted species (50.23%). We used a supermatrix approach using three DNA regions: ETS, ITS and matK. Every concatenated sequence was derived from a single specimen. The topology of our phylogenetic reconstruction largely agreed with previous studi...
Allan Herbarium (CHR), Landcare Research, New Zealand Plant Names Database (PND) provides a contemporary account of the names of New Zealand indigenous and naturalised plants. The PND lists nearly 50 000 scientific names, primarily for hornworts, lichens, liverworts, mosses, ferns and seed plants in New Zealand, as well as some information for fres...
Following the recircumscription of Carex to include Uncinia, a new name Carex auceps (de Lange & Heenan) K.A.Ford etHeenan is provided for Uncinia auceps.
Carex (Cyperaceae), with an estimated 2000 species, nearly cosmopolitan distribution and broad range of habitats, is one of the largest angiosperm genera and the largest in the temperate zone. In this article, we provide argument and evidence for a broader circumscription of Carex to add all species currently classified in Cymophyllus (monotypic),...
Twelve polymorphic simple sequence repeat markers were developed from transcribed sequences generated by RNA-seq. These were then used to assess relationships among selected putative species of Craspedia in Kahurangi National Park, New Zealand, including three putative species in sympatry at Mt Arthur; plants from two putative species from the near...
A family of about 34 species in three genera, Aphelia, Centrolepis and Gaimardia; two genera are represented in New Zealand: Centrolepis (4 indigenous and 1 introduced species) and Gaimardia (1 indigenous species). Generally they inhabit infertile and poorly drained soils - in New Zealand they arecommonly found in bogs, wet heathland or along the e...
A new indigenous species is recorded for the New Zealand flora, Centrolepis glabra, found in lakes
and kettlehole tarns of the inner montane basins of the South Island. Centrolepis glabra has previously
been known only from Australia. A description of C. glabra based on New Zealand material and notes
on habitat and distribution are provided. The na...

The identity of Craspedia macrocephala Hook. is determined and it is shown to be conspecific with C. alpina Backh. ex Hook.f., which, being the younger name, is therefore placed in synonymy. J.D.Hooker (1847, 1857) misapplied the name C. macrocephala and recognised two informal varieties. One of these varieties is described, herein, as a new specie...
Three morphologically distinct forms of Craspedia grow together in a small area of Mt Arthur (New Zealand) where they appear to remain distinct. Amplified fragment length polymorphism (AFLP) was investigated at the site. Although sample sizes were small, the results indicate that these three distinct forms are reproductively isolated from each othe...
Landcare Research Contract Report LC63.
New Zealand is diverse in alpine and subalpine environments, a consequence of Late Tertiary tectonic and climatic change. However, few studies have sought to evaluate the importance of these environments as abiotic drivers in the diversification of plant species. Of particular interest is the Late Tertiary radiation of Pachycladon, an endemic New Z...
Two new species of Carex are described from the mountains of North‐West Nelson, New Zealand. Both are endemic to the North‐West Nelson Ecological Region and are species of calcareous rock and derived substrates, Carex cremnicola of marble and C. calcis of limestone and calcareous mudstone. Carex cremnicola of section Elatae is similar to C. spiniro...
Craspedia (Asteraceae: Gnaphalieac) is a genus of 23 species found only in Australia and New Zealand. Maxiinum parsimony arid maximum likelihood analyses of ITS and ETS intergenic spacers from the nuclear genome recovered three main lineages. The first lineage consists solely of the Australian species C. haplorrhiza, the relationships of which are...

Carex impexa is named and described from the Tertiary limestone mountains of the Nelson Region, New Zealand, where it is endemic. This species is most closely related to C. dallii but differs in its broader and more stiffly reflexed leaves, congested spikes, and beakless to scarcely beaked utricles. C. impexa is a calcicole of montane to subalpine...
