Atriplex hollowayi, also known as Holloway's crystalwort, is a species of annual herbaceous plant in the genus Atriplex . [2] This species is endemic to New Zealand. [2] It has the "Nationally Critical" conservation status under the New Zealand Threat Classification System. [1]
Atriplex hollowayi is a soft, succulent annual plant. The stem and leaves look like they are coated with sugar crystals. [3] The plant is a many-branch shrub that grows in sand to a diameter of 80–120 cm (31–47 in), the yellow branches themselves 1–5 cm (0.4–2.0 in) long. The smooth, roughly oval leaves are 2–12 mm (0.08–0.47 in) long by 1–6 mm (0.04–0.24 in) wide with irregular dentate (toothed) margins. [4]
Atriplex hollowayi was described in 2000 by New Zealand botanists Peter de Lange and David Norton, who distinguished it from the widespread Atriplex billardierei . On reviewing the herbarium specimens of the latter species, de Lange noted there were two distinct forms: one with larger leaves with entire margins, and larger bracteoles and seeds, and one with smaller leaves with irregular sinuate-dentate margins and smaller bracteoles and seeds. This latter form was restricted to the North Island, and following field work was described as a new species, its name honouring botanist and conservationist John Stevenson Holloway, who had died in 1999. [4]
It inhabits the strand line, the unvegetated stable sand above the high tide line. [3] It was once found on beaches from Northland to Wellington. Now it is only found on one beach, with a population estimated at fewer than 50 plants. The reason for its decline is unknown. [5]
Banksia dentata, commonly known as the tropical banksia, is a species of tree in the genus Banksia. It occurs across northern Australia, southern New Guinea and the Aru Islands. Growing as a gnarled tree to 7 m (23 ft) high, it has large green leaves up to 22 cm (8.7 in) long with dentate (toothed) margins. The cylindrical yellow inflorescences, up to 13 cm (5.1 in) high, appear over the cooler months, attracting various species of honeyeaters, sunbirds, the sugar glider and a variety of insects. Flowers fall off the ageing spikes, which swell and develop follicles containing up to two viable seeds each.
Acacia denticulosa, commonly known as sandpaper wattle, is a species of Acacia native to the south-west of Western Australia. A spindly shrub 1–4 m high, it flowers from September to October, producing dense, curved, yellow flower spikes.
Atriplex semibaccata, commonly known as Australian saltbush, berry saltbush, or creeping saltbush, is a species of flowering plant in the family Amaranthaceae and is endemic to Australia. It is a perennial herb native to Western Australia, South Australia, Queensland and New South Wales, but has been introduced into other states and to overseas countries. It flowers and fruits in spring, and propagates from seed when the fruit splits open. This species of saltbush is adapted to inconsistent rainfall, temperature and humidity extremes and to poor soil. It is used for rehabilitation, medicine, as a cover crop and for fodder. Its introduction to other countries has had an environmental and economic impact on them.
Pittosporum obcordatum, commonly called heart-leaved kohuhu or heart-leaved kohukohu or kohukohu, is a species of plant in the Pittosporaceae family. It is endemic to New Zealand, and exists both in North Island and South Island.
Atriplex cinerea, commonly known as grey saltbush, coast saltbush, barilla or truganini, is a plant species in the family Amaranthaceae. It occurs in sheltered coastal areas and around salt lakes in the Australian states of Western Australia, South Australia, Tasmania, Victoria and New South Wales.
Atriplex nummularia is a species of saltbush from the family Amaranthaceae and is a large woody shrub known commonly as oldman saltbush. A. nummularia is native to Australia and occurs in each of the mainland states, thriving in arid and semi-arid inland regions.
Extriplex is a plant genus in the subfamily Chenopodioideae of the family Amaranthaceae. It has been described in 2010 and comprises two species, that were formerly included in genus Atriplex. They are restricted to the California Floristic Province.
Stutzia is a plant genus in the subfamily Chenopodioideae of the family Amaranthaceae. It was described in 2010, replacing the illegitimate name Endolepis. It comprises two species, that have also been included in the genus Atriplex.
Lachnagrostis billardierei, commonly known as coast blown-grass or sand wind grass, is a species of plant in the true grass family. The genus name means “woolly agrostis” with reference to the closely related genus Agrostis; the specific epithet billardierei honours French botanist Jacques Labillardière (1755-1834).
Carex pumila, commonly known as strand sedge or spreading sedge, is a species of sedge of the family Cyperaceae.
Leptinella filiformis, or slender button daisy, is a species of flowering plant in the daisy family, found only in the north-eastern part of the South Island of New Zealand. Thought to be extinct by the 1980s, it was rediscovered growing on a Hanmer Springs hotel lawn in 1998, and in the wild in 2015.
Carmichaelia juncea, the braided riverbed broom, is a species of New Zealand broom, a prostrate shrub in the family Fabaceae that is endemic to New Zealand. It is extinct over much of its former range, including the North Island.
Acacia pickardii, commonly known as Pickard's wattle or birds nest wattle, is a tree or shrub belonging to the genus Acacia and the subgenus Phyllodineae native to eastern Australia. It is listed as a vulnerable species according to Environment Protection and Biodiversity Conservation Act 1999.
Dracophyllum arboreum, commonly known as Chatham Island grass tree and tarahinau (Moriori), is a species of tree in the heath family Ericaceae. Endemic to the Chatham Islands of New Zealand, it reaches a height of 18 m (60 ft) and has leaves that differ between the juvenile and adult forms.
Carmichaelia hollowayi is a species of plant in the family Fabaceae. It is found only in the South Island of New Zealand. Its conservation status (2018) is "Nationally Critical" under the New Zealand Threat Classification System.
Marsippospermum gracile, common name - alpine rush, is a flowering plant species in the rush family Juncaceae which is native to New Zealand.
Veronica jovellanoides, commonly known as Riverhead speedwell, is a threatened flowering plant in the family Plantaginaceae. Endemic to New Zealand, only three plants are known in the wild. All are found within the Ernest Morgan Reserve, a 20 ha forest northwest of Auckland. Its discovery is accredited to a retired plant nursery owner, Geoff Davidson, who organised the land's protection a few decades prior, and found it by chance on a walk in November 2007.
Dracophyllum fiordense, commonly known as the Fiordland grass tree, is a species of tree or shrub in the heath family, Ericaceae. It is endemic to the South Island of New Zealand. It reaches a height of 1.5–5.0 metres and has tufts of long green leaves at the ends of its branches. Each leaf has a distinctive curled spiral tip. D. fiordense has a pyramid-shaped inflorescence hidden under each clump of leaves, with between 113 and 120 pink flowers on each spike, and later reddish-brown dry fruit; both are around just 2 by 2 mm. It inhabits shrubland, lowland and subalpine forests, and tussock grassland of mountain slopes, gullies, and ridges. Its range covers two main areas: one in Fiordland National Park, and one in the Mount Cook and Westland National Parks.
Celmisia major is a species of daisy that is endemic to New Zealand. It is split into two different varieties, Celmisia major var. major and Celmisia major var. brevis. Despite being in the same species, it is thought that the two varieties are not close to one another, with botanist Peter James de Lange stressing critical study on the taxonomy of the daisies. It was first described by Thomas Cheeseman in 1925. The major variety is found in the Auckland area and nearby islands, while the brevis variety is confined to Mount Taranaki.
Atriplex sturtii, commonly known as saltbush, is an endangered species within the widespread genus Atriplex.A. sturtii is a native Australian shrub and grows in the Channel Country bioregion, also referred to as 'Corner Country'.
