Nageia nagi, the Asian bayberry, is plant species in the family Podocarpaceae named by Carl Peter Thunberg. Nageia nagi is native to China, Japan, and Taiwan. [2] It was formerly called Podocarpus nagi.
Nageia nagi is a hardy tree species that can withstand a range of weather conditions, but it prefers moist sites that are well drained and with full sunlight to light shade. Being from the family Podocarpaceae, it is a dioecious tree, that is, the male and female parts of the trees are on separate plants. [2] The pollen cones are catkins and the female cones, which mature in one year, are reduced fleshy bracts that contain a single inverted ovule. It requires wind for pollination; it cannot self-pollinate. [3]
The trees range from fifteen to twenty meters in height and are relatively slow growing. [4] The leaves are lanceolate in shape, and are arranged sub opposite on the branches. Leaves range from two to eight inches long and 0.75 to 2.5 inches wide and lack a mid-vein. The new leaves are a light green and as they age they become dark green and glossy. The branches also start out as green but as they age they become reddish brown and peel in small layers. [2]
Nageia nagi can be propagated by cuttings or by seed. It is best to plant the seed in a warm greenhouse and sandy soil. For their permanent position, they should be planted in late spring or early summer after the last frost. [5]
The species is threatened by habitat loss.
Houses, bridges, utensils, handiwork and furniture are constructed from the wood. The seeds yield an oil that is edible and valued in industry. [6] Young leaves are sometimes cooked and eaten. [5] Its bark exhibits strong antibacterial effect. [7] Stems are used in floral arrangements that last in water for up to a year. [8]
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta, also known as Coniferophyta or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 living species.
The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes, forming the clade Gymnospermae. The term gymnosperm comes from the composite word in Greek: γυμνόσπερμος, literally meaning 'naked seeds'. The name is based on the unenclosed condition of their seeds. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants (angiosperms), which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or on their own as in yew, Torreya, Ginkgo. Gymnosperm lifecycles involve alternation of generations. They have a dominant diploid sporophyte phase and a reduced haploid gametophyte phase which is dependent on the sporophytic phase. The term "gymnosperm" is often used in paleobotany to refer to all non-angiosperm seed plants. In that case, to specify the modern monophyletic group of gymnosperms, the term Acrogymnospermae is sometimes used.
Agathis, commonly known as kauri or dammara, is a genus of evergreen coniferous trees, native to Australasia and Southeast Asia. It is one of three extant genera in the family Araucariaceae, alongside Wollemia and Araucaria. Its leaves are much broader than most conifers. Kauri gum is commercially harvested from New Zealand kauri.
Platycladus is a monotypic genus of evergreen coniferous trees in the cypress family Cupressaceae, containing only one species, Platycladus orientalis, also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or Oriental thuja. It is native to northeastern parts of East Asia and North Asia, but is also now naturalised as an introduced species in other regions of the Asian continent.
Podocarpus is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς + καρπός. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m tall, known to reach 40 m (130 ft) at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their droppings. About 97 to 107 species are placed in the genus depending on the circumscription of the species.
Nageia is a genus of conifers belonging to the podocarp family Podocarpaceae. Nageia includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species. Some authors consider Nageia formosensis to be a separate species from Nageia nagi, thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as Nageia were moved to the new genus Retrophyllum, while Nageia falcata and Nageia mannii were moved to the new genus Afrocarpus.
Pinus kesiya is one of the most widely distributed pines in Asia. Its range extends south and east from the Khasi Hills in the northeast Indian state of Meghalaya, to northern Thailand, Philippines, Burma, Cambodia, Laos, southernmost China, and Vietnam. It is an important plantation species elsewhere in the world, including in southern Africa and South America.
Myrica is a genus of about 35–50 species of small trees and shrubs in the family Myricaceae, order Fagales. The genus has a wide distribution, including Africa, Asia, Europe, North America, and South America, and missing only from Antarctica and Oceania. Some botanists split the genus into two genera on the basis of the catkin and fruit structure, restricting Myrica to a few species, and treating the others in Morella.
Myrica rubra, also called yangmei, yamamomo, Chinese bayberry, red bayberry, yumberry, waxberry, or Chinese strawberry is a subtropical tree grown for its fruit.
Retrophyllum is a genus of conifers in the family Podocarpaceae. It contains five generally recognized extant species with a disjunct distribution in the Southern Hemisphere, found in Papuasia and also in South America. Retrophyllum are evergreen trees typically occurring in tropical rainforests and cloud forests.
Diselma archeri is a species of plant of the family Cupressaceae and the sole species in the genus Diselma. It is endemic to the alpine regions of Tasmania's southwest and Central Highlands, on the western coast ranges and Lake St. Clair. It is a monotypic genus restricted to high altitude rainforest and moist alpine heathland. Its distribution mirrors very closely that of other endemic Tasmanian conifers Microcachrys tetragona and Pherosphaera hookeriana.
Larix kaempferi, the Japanese larch or karamatsu in Japanese, is a species of larch native to Japan, in the mountains of Chūbu and Kantō regions in central Honshū.
Phyllocladus aspleniifolius, commonly known as the celerytop pine, is an endemic gymnosperm of Tasmania, Australia. It is widespread and common in Tasmania, with the most abundance in the western highlands. Its ‘leaves’ appear similar to those of a celery plant, hence the common name.
Afrocarpus falcatus is a species of tree in the family Podocarpaceae. It is native to the montane forests of southern Africa, where it is distributed in Malawi, Mozambique, South Africa, and Eswatini. Common names include common yellowwood, bastard yellowwood, outeniqua yellowwood, African pine tree, weeping yew, Afrikaans: outeniekwageelhout, kalander, Sotho: mogôbagôba, Xhosa: umkhoba and Zulu: umsonti. It is widespread, in some areas abundant, and not considered threatened, but it is a protected tree in South Africa. It is grown as an ornamental tree, especially in South Africa, and occasionally abroad.
Nageia wallichiana is a species of conifer in the family Podocarpaceae. It is a tree 10–54 m high, found in Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam. Nageia wallichiana is the most widely distributed species among the seven species in the genus Nageia. If the land areas of China and Japan are excluded, its distribution nearly coincides with that of the genus and includes both the western outliers in India and the easternmost part on Normanby Island. It is one of the most extensive conifer ranges recognized and is similar to Dacrycarpus imbricatus and Podocarpus neriifolius.
Phyllocladus toatoa, known as toatoa (Māori) or blue celery pine is a species of conifer in the family Podocarpaceae, endemic to New Zealand. It was formerly referred to as P. glaucus.
Podocarpus coriaceus, commonly known as the yucca plum pine, is a species of conifer, an evergreen tree in the family Podocarpaceae. It is found in the Dominican Republic, Guadeloupe, Martinique, Montserrat, Puerto Rico, and Saint Kitts and Nevis.
Prumnopitys exigua is a species of conifer in the family Podocarpaceae. It is endemic to Bolivia.
Retrophyllum vitiense is a species of conifer in the family Podocarpaceae. It is a large evergreen rainforest emergent tree native to Fiji, Vanuatu, and the Santa Cruz Islands.
Myrica cerifera is a small evergreen tree or large shrub native to North and Central America and the Caribbean. Its common names include southern wax myrtle, southern bayberry, candleberry, bayberry tree, and tallow shrub. It has uses in the garden and for candlemaking, as well as a medicinal plant.
