“…The most common one is protogyny and less commonly protandry (see 'Glossary' and Al-Shehbaz, 1977). Dioecism in known in two species of Lepidium endemic to New Zealand (Heenan et al, 2007), and gynodioecism is extremely rare in the family (Garnock-Jones, 1991).…”

The Brassicaceae (Cruciferae) or mustard family is a well‐defined group of about 310 genera and some 3500 species distributed primarily in the temperate and alpine areas of all continents except Antarctia. It is most highly diversified in central and western Asia, Mediterranean Europe and western North America. This article discusses the economic importance of the family (food, oils, condiments, ornamentals and weeds) and role played by one of its weedy member, the model organism Arabidopsis thaliana , in the advancement of modern experimental biology. Here we also review the morphology, biogeography, ecology and phylogenetic relationship within Brassicaceae and to other families. We also cover the significance of molecular data in dividing the family into 48 monophyletic tribes and in determining its major lineages. Finally, a brief discussion is presented on the whole‐genome duplication events and their possible role in the radiation and diversification of the family. Key Concepts: Model organisms, such as the mustard Arabidopsis thaliana , should always be used to understand complex biological phenomena in other organisms. Owing to extensive morphological convergence, molecular data alone provide the most reliable and solid phylogenetic classification within the Brassicaceae. Invasive weeds of the mustard family can only be understood by closer studies of their immediate wild relatives. Germplasm conservation centres of the economically important Brassicaceae should substantially increase their efforts to save their rapidly disappearing wild relatives. Vegetable crops of Brassica should be thoroughly tested to determine their medicinal values in combating cancer and other diseases.

“…The primer jkETS-9 was designed by Jeanette Keeling, Auckland University, by comparing published ETS sequences from Solanaceae, Brassicaceae, and Asteraceae in the region around the conserved "9bp motif ATG AGT GGT and is published here with her permission. Temperature and cycling conditions for ETS were as described by Heenan et al (2007) and for ITS amplifications were as follows: one 94°C denaturation cycle for 3 min, followed by 10 cycles of 94°C denaturation for 45 s, primer annealing at 53°C for 45 s, and elongation at 72°C for 1 mm, followed by 12 cycles of 94°C for 45 s, 50°C for 45 s, 72°C for 1 mm, followed by 14 cycles of 94°C for 45 s, 48°C for 45 s, 72°C for 1 mm, and finally an elongation at 72°C for 7 min.…”

New Zealand species of Geranium are shown to be closely related, forming a monophyletic group. Relationships inferred from Bayesian and NeighborNet analyses of internal and external transcribed spacer sequences generally agreed and were congruent with those inferred from study of morphological characters. Two groups of species (G. brevicaule and G. retrorsum groups) are well supported based on morphology and DNA sequence data. A third group, referred to as the G. microphyllum group, is recognised based on morphology but is only partially supported by the DNA sequence data. The DNA sequence and morphological variability in each of the G. brevicaule, G. microphyllum, and G. retrorsum groups support the recognition of additional taxonomic entities from New Zealand, but further study is required to address these issues. Furthermore, additional sampling of Australian and South American species of Geranium must be carried out before a taxonomic re-evaluation can be made of sections Andina and Chilensia.

“…As currently circumscribed, the New Zealand members of the cosmopolitan genus Lepidium comprise 10 indigenous species (Garnock-Jones 1988; Garnock-Jones and Norton 1995; Heenan et al 2007). Recently, the New Zealand species have been the subject of ongoing research that has resulted in new circumscriptions of the inland species Lepidium sisymbrioides Hook.f.…”

“…Recently, the New Zealand species have been the subject of ongoing research that has resulted in new circumscriptions of the inland species Lepidium sisymbrioides Hook.f. and Lepidium solandri Kirk (Heenan et al 2007), as well as the publication of phylogenetic (Mitchell and Heenan 2000; Mummenhoff et al 2004) and evolutionary studies (Dierschke et al 2009). There are an additional 16 species naturalised in New Zealand (Garnock-Jones 1988; Webb et al 1995; Howell and Sawyer 2006; Heenan and de Lange 2011), including species that have previously been assigned to Coronopus Zinn and Cardaria Desv.…”

A revision of the New Zealand endemic Lepidium oleraceum and allied species is presented. Sixteen species are recognised, 10 of these are new. The new species are segregated on the basis of morphological characters supported by molecular data obtained from three DNA markers (two rDNA and one cpDNA). One species, Lepidium castellanum sp. nov., is endemic to the Kermadec Islands where it is sympatric with Lepidium oleraceum. The North Island of New Zealand supports four species, with two of them, Lepidium amissum sp. nov. and Lepidium obtusatum, now extinct. The South Island supports six species, that, aside from Lepidium banksii, Lepidium flexicaule and Lepidium oleraceum, are all confined to the south-eastern half of the island (Lepidium aegrum sp. nov., Lepidium crassum sp. nov. and Lepidium juvencum sp. nov.). One of these, Lepidium juvencum sp. nov., extends to Stewart Island. The Chatham Islands support six species (Lepidium flexicaule, Lepidium oblitum sp. nov., Lepidium oleraceum, Lepidium oligodontum sp. nov., Lepidium panniforme sp. nov., and Lepidium rekohuense sp. nov.), one of which, Lepidium oligodontum sp. nov., extends to the Antipodes Islands group. The remote, subantarctic Bounty Islands group supports one endemic, Lepidium seditiosum sp. nov., which is the only vascular plant to be recorded from there. Lepidium limenophylax sp. nov. is known from islands off the south-western side of Stewart Island/Rakiura, The Snares and Auckland islands. Lepidium naufragorum, although not related to Lepidium oleraceum and its allies, is also treated because populations with entire leaves are now known. Typification is undertaken for Lepidium banksii, Lepidium oleraceum, Lepidium oleraceum var. acutidentatum, var. frondosum and var. serrulatum.

Natural variation and conservation ofLepidium sisymbrioidesHook, f. andL. solandriKirk (Brassicaceae) in South Island, New Zealand, based on morphological and DNA sequence data

Abstract: Lepidium sisymbrioides and L. solandri are considered to be "Acutely Threatened, Nationally Endangered" using the New Zealand threatened plant classification criteria. In this assessment both species are considered to be data poor. Further field survey for new populations is required.
