Species [1]

Pseudopanax (Latin for "false ginseng") is a small genus of 7 species of evergreen plants which are endemic to New Zealand. [1] Flowers of the genus occur in terminal umbels. [2]

Taxonomy

A 2000 molecular study established that several species within the genus were only distantly related to the core group of New Zealand species related the type species P. crassifolius. They were removed to the genus Raukaua . [3]

Distribution and habitat

Pseudopanax occur in forest or scrub environments. The genus contains some remarkable small trees with distinctly different juvenile and adult forms, such as Pseudopanax crassifolius and Pseudopanax ferox (commonly referred to as 'lancewood' and 'toothed lancewood', respectively).

Cultivation

Many of the species are popular in New Zealand gardens, but are rather rare in cultivation elsewhere, requiring mild, moist conditions similar to those in New Zealand, without extremes of temperature in winter and summer. They reportedly grow well in Southern California and warmer parts of Great Britain. A number of cultivars have been developed, mostly of Pseudopanax lessonii. These include 'Gold Splash', which has yellow variegated leaves, and 'Nigra' which has dark purple-brown foliage. A National Trust listed specimen of Pseudopanax crassifolius exists on the Alton property at Mount Macedon, Victoria, Australia, which is 21 metres high and has an 11.5 m spread. Its age is estimated at 100 years. [4]

Host plant

In New Zealand various species in this genus have been shown to be the host plant for the larvae of Scolopterus penicillatus , a common endemic weevil. The larvae develop in recently dead bark. [5]

<i>Meryta sinclairii</i> Species of tree

Meryta sinclairii, the puka or pukanui, is a large-leaved evergreen tree endemic to New Zealand that grows to about 8 m tall, with the distinctly tropical appearance typical of the genus. There are about 27 species of Meryta, all small, resinous trees of the subtropical and tropical Pacific Ocean.

<i>Dacrycarpus dacrydioides</i> Coniferous tree endemic to New Zealand

Dacrycarpus dacrydioides, commonly known as kahikatea and white pine, is a coniferous tree endemic to New Zealand. A podocarp, it is New Zealand's tallest tree, gaining heights of 60 m over a life span of 600 years. It was first described botanically by the French botanist Achille Richard in 1832 as Podocarpusdacrydioides, and was given its current binomial name Dacrycarpus dacrydioides in 1969 by the American botanist David de Laubenfels. Analysis of DNA has confirmed its evolutionary relationship with other species in the genera Dacrycarpus and Dacrydium.

<i>Urtica ferox</i> Species of plant

Urtica ferox, commonly known as tree nettle and in Māori: ongaonga, taraonga, taraongaonga, оr okaoka, is a species of nettle endemic to New Zealand. Unlike the other species in the genus Urtica found in New Zealand, all of which are herbaceous, ongaonga is a large woody shrub that can grow to a height of 3 m (9.8 ft), with the base of the stem reaching 12 cm (4.7 in) in thickness. It has large spines that can result in a painful sting that lasts several days.

<i>Pseudopanax crassifolius</i> Species of tree

Pseudopanax crassifolius, the horoeka or lancewood, is a New Zealand native tree belonging to the family Araliaceae. It is found throughout New Zealand from sea level up to about 750 m. The juvenile form, which lasts for between 15 and 20 years, is very easily recognized. The leaves are stiff and leathery with a prominent central rib, about 1 cm wide and up to 1 m long with irregular teeth, all growing downwards from a central stem. The young trunk has characteristic vertical swollen ridges. As the tree gets older the stem begins to branch, producing a bushy top, and the leaves become wider and shorter, losing their teeth. It is only when the tree is mature that it adopts a typical tree shape.

<i>Pseudopanax ferox</i> Species of tree

Pseudopanax ferox, the toothed lancewood or horoeka, is a small tree endemic to New Zealand. It is similar to the more common lancewood, Pseudopanax crassifolius, but with more prominently tooth-shaped leaves. The juvenile leaves are a very dark grey-brown to grey-green colour, narrow, stiff and up to 40 cm long. Once the slow growing tree reaches maturity at 10 to 15 years, the leaf form becomes shorter, wider and dark green in colour. It is only in adulthood that the tree's shape changes from one central stem and downward growing leaves to a more typical tree shape with branches spreading to build a round head. A mature toothed lancewood can reach 6 metres height with a trunk of up to 25 cm in diameter. The mature trunk has distinctive longitudinal grooves which sometimes twist slightly.

<i>Raukaua</i> Genus of flowering plants

Raukaua is a genus of flowering plants in the family Araliaceae. It has an austral distribution, being indigenous to southern Argentina and Chile, as well as New Zealand and the island of Tasmania.

<i>Pseudopanax lessonii</i> Species of tree

<i>Schefflera digitata</i> Species of tree

Schefflera digitata, the patē, seven-finger, or umbrella tree, is a tree endemic to New Zealand belonging to the family Araliaceae. Māori names include: patē, patatē, patete, and kōtētē. It occurs in lowland to lower montane forests from sea level to 1,200 m (3,900 ft) in the North Island, South Island, and Stewart Island, covering a latitudinal range from 34°S to 47°S. It prefers damp, shady parts of the forest and is common along stream banks and on shady forest roadsides. It is the only New Zealand representative of the genus Schefflera, which has 12 other species on the Pacific islands.

<i>Nestegis</i> Genus of flowering plants

<i>Circoxena ditrocha</i> Species of moth

Circoxena ditrocha is a species of moth in the family Blastodacnidae. This species is endemic to New Zealand and has been collected on both the North and South Islands. The habitat of this species is on the edges of native forest or scrub and it may be associated withPseudopanax arboreus. As at 2000 the host species of this moth is unknown but it has been hypothesised that the larvae are seed borers. Adults are on the wing in December to March. It is classified as "At Risk, Naturally Uncommon" by the Department of Conservation.

<i>Pterophorus monospilalis</i> Species of plume moth

Pterophorus monospilalis, the white plume moth, is a moth of the family Pterophoridae. It is endemic to New Zealand and occurs throughout the country. It inhabits native forest, parks and domestic gardens. Larvae are active during the day, are slow moving, and feed exposed. They feed on Pseudopanax species as well as on Hedera helix, Meryta sinclairii, and Schefflera digitata. There are several broods in a year. Adult moths are on the wing from November until May and are attracted to light.

<i>Declana egregia</i> Species of moth

Declana egregia, commonly called the South Island lichen moth or zebra lichen moth, is a moth in the family Geometridae, endemic to New Zealand. This species was first described by entomologists Baron Cajetan von Felder and Alois Friedrich Rogenhofer in 1875 under the name Chlenias egregia.

<i>Austramathes fortis</i> Species of moth

Austramathes fortis is a species of moth in the family Noctuidae. It is endemic to New Zealand and is found in both the North and the South Islands but has yet to be recorded at Stewart Island. It can be found in shrubland containing its host species at a range of altitudes from sea-level up to 1840 m. The larvae of this moth feed on several Melicytus species including M. crassifolius, M. alpinus, M. macrophyllus and M. novae-zelandiae. The larvae pupate in a cocoon of silk at the base of its host plant. It can take between 25 and 45 days before the adult moth emerges. Adults can be found on the wing during the months of July to March. The adults tend to be on the wing in twilight hours but have also been known to be active during the late afternoon. They are attracted to light but this behaviour may limit the number seen at light traps. The distinguishing feature of this moth is the curved black line at the base of its forewing. This species is unlikely to be confused with any other species in its range but it is very similar in appearance to A. squaliolus. However this latter species is only found on the Chatham Islands.
