Whau
''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, particularly '' Hibiscus tiliaceus'', which it superficially resembles. Alternate names include 'New Zealand mulberry', 'corkwood' and 'evergreen lime'. Description Within the Malvaceae, ''Entelea'' is placed within tribe Sparrmannieae and subfamily Grewioideae, a position confirmed by ndhF DNA sequence data. As is the case with most malvaceous plants, ''E. arborescens'' has alternate, stipulate foliage. The bright green, obliquely cordate leaves a ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Coprosma Macrocarpa
''Coprosma macrocarpa'', also known as large-seeded coprosma and coastal karamu, is a shrub native to New Zealand. It has large thick leaves and large bright red/orange berries. ''Macrocarpa'' means "large fruit". There are two subspecies. C. macrocarpa subsp. macrocarpa ranges from a shrub to a 10 metre tall tree. It occurs naturally on the Three Kings Islands. It is naturalised in the northern part of the North Island and around Wellington. C. macrocarpa subsp. minor is mostly a shrub up to 4 metres. It occurs in coastal areas from North Cape to East Cape and some offshore islands. References Flora of New Zealand macrocarpa ''Hesperocyparis macrocarpa'' is a coniferous tree.

Macropiper Excelsum
''Piper excelsum'' (formerly known as ''Macropiper excelsum''), of the Pepper Family (Piperaceae) commonly known as kawakawa, is a small tree to 20 feet (six meters)of which the subspecies ''P. excelsum'' subsp. ''excelsum'' is endemic to New Zealand; the subspecies ''P. e.'' subsp. ''psittacorum'' is found on Lord Howe Island, Norfolk Island and the Kermadec Islands. Description Kawakawa is found throughout the North Island, and as far south as Okarito (43.20 °S) on the West Coast, and Banks Peninsula (43.5 °S) on the east coast of the South Island. The leaves are often covered with holes caused by the caterpillar of the kawakawa looper moth (''Cleora scriptaria''). The images depict the variety ''majus'' which has larger and more glossy leaves than ''P. excelsum''. The name ''kawakawa'' comes from the Māori language, where it refers to the bitter taste of the leaves, from ''kawa'' or bitter. Leaves Kawakawa leaves are about 5–10 cm long by 6–12 cm wide ...

Urtica Ferox
''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 , with the base of the stem reaching in thickness. It has large spines that can result in a painful sting that lasts several days. Ongaonga is the main source of food for larvae of the New Zealand red admiral butterfly or kahukura, ''Vanessa gonerilla''. Description ''U. ferox'' 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. The pale green leaves are very thin like a membrane and the surface of the leaf, stems and stalks are covered in stiff stinging hairs that can grow up to long. These spines are prominent along the salient mid-vein and leaf margin. The leaves range from in width and in le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hen And Chicken Islands
The Hen and Chicken Islands (usually known collectively as the ''Hen and Chickens'') lie to the east of the North Auckland Peninsula off the coast of northern New Zealand. They lie east of Bream Head and south-east of Whangarei with a total area of . History Approximately 18,000 years ago during the Last Glacial Maximum when sea levels were over 100 metres lower than present day levels, the islands were hilly features surrounded by a vast coastal plain. Sea levels began to rise 7,000 years ago, after which the islands separated from the rest of New Zealand. These islands were given their European name by Captain James Cook, who first sighted them on 25 November 1769. It has been suggested that the name was inspired by an old name for the star cluster usually known as the Pleiades. Originally owned by the Māori Ngā Puhi iwi, they were sold to the New Zealand Government in 1883. The islands were made a scenic reserve in 1908 owing to the rarity of their flora and fau ...

Parenchyma
Parenchyma () is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology it is the name for the tissue that fills the interior of flatworms. Etymology The term ''parenchyma'' is New Latin from the word παρέγχυμα ''parenchyma'' meaning 'visceral flesh', and from παρεγχεῖν ''parenchyma'' meaning 'to pour in' from παρα- ''para-'' 'beside' + ἐν ''en-'' 'in' + χεῖν ''chyma'' 'to pour'. Originally, Erasistratus and other anatomists used it to refer to certain human tissues. Later, it was also applied to plant tissues by Nehemiah Grew. Structure The parenchyma is the ''functional'' parts of an organ (anatomy), organ, or of a structure such as a tumour in the body. This is in contrast to the Stroma (animal tissue), stroma, which refers to the ''structural'' tissue of organs or of structures, namely, the connective tissues. Brain The brain parenchyma refers to the functional tissue in the brain that is made up of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pith
Pith, or medulla, is a tissue in the stem Stem or STEM may refer to: Plant structures * Plant stem, a plant's aboveground axis, made of vascular tissue, off which leaves and flowers hang * Stipe (botany), a stalk to support some other structure * Stipe (mycology), the stem of a mushro ...s of vascular plants. Pith is composed of soft, spongy ground tissue#Parenchyma, parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends also into flowering stems and roots. The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem. While new pith growth is usually white or pale in color, as the tissue ages it commonly darkens to a deeper brown color. In trees pith is generally present in young growth, but in the trunk and older branches the pith often gets replaced – in great part – by xylem. In some plants, the pith in the middle of the stem may dry out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Net
A fishing net is a net used for fishing. Nets are devices made from fibers woven in a grid-like structure. Some fishing nets are also called fish traps, for example fyke nets. Fishing nets are usually meshes formed by knotting a relatively thin thread. Early nets were woven from grasses, flaxes and other fibrous plant material. Later cotton was used. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used. History Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Finland, in 1913. The net was made from willow, and dates back to 8300 BC. Recently, fishing net sinkers from 27,000 BC were discovered in Korea, making them the oldest fishing implements discovered, to date, in the world. The remnants of another f ...
