Pennantia Baylisiana
''Pennantia baylisiana'', commonly known as Three Kings kaikōmako or (Māori), is a species of plant in the family Pennantiaceae (Icacinaceae in older classifications). It is endemic to Manawatāwhi / Three Kings Islands, around northwest of Cape Reinga, New Zealand. At the time of its discovery just one plant remained. This single tree grows on a scree slope inaccessible to browsing goats, and has been called "the world's loneliest tree". The species was discovered in 1945 by botanist Geoff Baylis and described in 1948, although it took decades before it was it was fully accepted as a distinct species of ''Pennantia''. Although the only wild tree is female, it was successfully propagated from cuttings in the 1950s, one of which was induced to self-pollinate in 1985. Subsequent seed-grown plants have themselves set seeds, and the species has been replanted on the island, the adjoining mainland, and in public and private gardens around New Zealand.

NZTCS
The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some shortcomings for the unique requirements of conservation ranking in New Zealand. plants, animals, and fungi are evaluated, though the lattermost has yet to be published. Algae were assessed in 2005 but not reassessed since. Other protists have not been evaluated. Categories Species that are ranked are assigned categories: ;Threatened This category has three major divisions: ::*Nationally Critical - equivalent to the IUCN category of Critically endangered ::*Nationally Endangered - equivalent to the IUCN category of Endangered ::*Nationally Vulnerable - equivalent to the IUCN category of Vulnerable ;At Risk This has four categories: ::*Declining ::*Recovering ::*Relict ::*Naturally Uncommon ;Other categories ;;Introduced and Natur ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Nestegis Apetala
''Nestegis apetala'' is a small tree native to northern New Zealand and to Norfolk Island. The common names in New Zealand are coastal maire or broad-leaved maire. On Norfolk Island, the common name is ironwood. The species name ''apetala'' refers to the lack of petals on the flowers.

It is also found on northern offshore islands including the Hen and Chickens Islands, Great Barrier Island, Little Barrier Island, and the Poor Knights Islands. It tends to be rare on islands with rats. On Norfolk Island, it is common on Mt Pitt, and in forested areas generally, but is less common elsewhere. Description ''Nestegis apetala'' is shrub or tree up to 6 m tall, with smooth, shiny dark green leaves 4.5 to 12 cm long and 1.5 to 4 cm wide.

Karaka (tree)
Karaka or New Zealand laurel (''Corynocarpus laevigatus'') is an evergreen tree of the family Corynocarpaceae endemic to New Zealand. It is common throughout the North and South Islands to Banks Peninsula (43°45′S) and Okarito (43°20′S), on the Three Kings Islands, on Raoul Island in the Kermadecs, and on the Chatham Islands. It is widespread in coastal habitats, often forming a major component of coastal forest, though it rarely dominates. Most botanists consider it to be native only to the northern half of the North Island, having been planted elsewhere by Māori near former village sites, and subsequently spread by birds. The common name karaka comes from the Māori language, and is also the Māori term for the colour orange, from the colour of the fruit. In the Chatham Islands, it is called ''kōpī'', its name in the Moriori language. It is naturalised and considered invasive in Hawaii.

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...
