Ascarina lucida

Ascarina lucida, commonly known as hutu is a species of small tree in the family Chloranthaceae. It is endemic to New Zealand, being common on the West Coast and Nelson regions of the South Island and more rarely found in the North Island. [2] A typical plant association is within the Westland podocarp/broadleaf forests with common understory associates of Blechnum discolor , Pseudowintera colorata , Pseudopanax colensoi and Coprosma lucida . [3] Most genus members are dioecious, producing unisexual male or female flowers on separate plants. Ascarina lucida, the only member of its genus to occur in New Zealand, is monoecious. [4] It will grow to a height of 6m and can have a 30 cm trunk. The leaves which are in opposite pairs are simple, yellowish green in color, have a raised mid rib and are very similar to Laurelia novae-zelandiae. Their margins have prominent teeth which are dark colored at the tips. Ascarina lucida is now nearly extinct in the Taranaki region but was last reported in Oct 1969 at Mt Taranaki, near Pukeiti by Colin Ogle. [5]

Tolerance

The distribution of Ascarina lucida suggests an inability to survive severe frosts or droughts. Its environmental tolerance to climatic extremes was experimentally tested by exposing the seedlings to frost, drought, and waterlogged soil conditions. Ascarina lucida has a similar drought tolerance to Coprosma grandifolia , a species known to be drought intolerant; seedlings had considerable tolerance of waterlogged soils, but exhibited reduced root weights when severely waterlogged; and a frost of -2 °C resulted in complete mortality for seedlings sourced from lowland and sub montane populations. Abundance of Ascarina lucia in a place can partially own to a warm, wet climate. However, the early successional nature of this species also suggests that disturbance regime plays an important role in regulating its distribution and abundance. [6]

<i>Coprosma robusta</i> Species of tree

Coprosma robusta, commonly known as karamu, is a flowering plant in the family Rubiaceae, which is endemic to New Zealand. It can survive in many climates, but is most commonly found in coastal areas, lowland forests, or shrublands. Karamu can grow to be around 6 meters tall, and grow leaves up to 12 centimeters long. Karamu is used for a variety of purposes in human culture. The fruit that karamu produces can be eaten, and the shoots of karamu are sometimes used for medical purposes.

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

Coprosma is a genus of flowering plants in the family Rubiaceae. It is found in New Zealand, Hawaiian Islands, Borneo, Java, New Guinea, islands of the Pacific Ocean to Australia and the Juan Fernández Islands.

Chloranthaceae Family of flowering plants

Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales. It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms. They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies. The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016. Some species are used in traditional medicine. The type genus is Chloranthus. The fossil record of the family, mostly represented by pollen such as Clavatipollenites, extends back to the dawn of the history of flowering plants in the Early Cretaceous, and have been found on all continents.

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

Ascarina is an ancient, woody, angiosperm genus. It is a distinct genus of Chloranthaceae consisting of less than twenty species, found in the Australian region, the Pacific Islands and Madagascar. They can grow up to six metres tall and have a spread of approximately three metres. Ascarina are usually tropical cloud forest species which need high humidity to thrive, and are vulnerable to both frost and drought. There has been discussion and research on whether or not this genus and its family are primitive, or have become reduced over time. Another controversial topic for the genus is its relation to the Clavatipollenites, a fossilized pollen.

<i>Entelea</i> Genus of trees

Entelea arborescens or whau is a species of malvaceous tree endemic to New Zealand. E. arborescens is the only species in the genus Entelea. A shrub or small tree to 6 m with large lime-like leaves giving a tropical appearance, whau grows in low forest along the coast of the North Island and the northern tip of the South Island. The dry fruit capsules are very distinctly brown and covered with spines. The common name whau is a Māori word that appears to derive from the common Polynesian word for hibiscus, other malvaceous trees which whau superficially resembles. Alternate names include 'New Zealand mulberry', 'corkwood' and 'evergreen lime'.

<i>Nothofagus truncata</i> Species of tree

Nothofagus truncata, or hard beech, is a species of tree endemic to New Zealand. Its common name derives from the fact that the timber has a high silica content, making it tough and difficult to saw. Hard beech is a tree up to 30m tall occurring in lowland and lower montane forest from latitude 35°S to 42°30'S, that is, from the north of the North Island southwards to Marlborough and south Westland in the South Island. In Taranaki it forms almost pure stands on the rugged sandstone country there and is partially deciduous, dropping many of its leaves at the end of the winter. N. truncata became known as Fuscospora truncata after 2013 in New Zealand.

<i>Pseudowintera colorata</i> Species of shrub

Pseudowintera colorata, also known as mountain horopito or pepper tree, is a species of woody evergreen flowering trees and shrubs, part of family Winteraceae. The species is endemic to New Zealand. All Winteraceae are magnoliids, associated with the humid Antarctic flora of the southern hemisphere.

Plant community Collection of native photosynthetic organisms

A plant community is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance. In many cases there are several soil types present within a given plant community. This is because the soil type within an area is influenced by two factors, the rate at which water infiltrates or exits the soil, as well as the rate at which organic matter enters or decays from the soil. Plant communities are studied substantially by ecologists, due to providing information on the effects of dispersal, tolerance to environmental conditions, and response to disturbance of a variety of plant species, information valuable to the comprehension of various plant community dynamics.

<i>Coprosma arborea</i> Species of plant
