Libocedrus plumosa | |
Libocedrus plumosa, with the common name kawaka, is a species of Libocedrus that is endemic to New Zealand.
The tree is native to the North Island from south of 35°S and from Cape Farewell to Whanganui Inlet area and locally at the north end of the South Island, near Nelson (41° S). [2]
It grows from sea level up to 600 metres (2,000 ft) in altitude, in temperate rainforests.
It is an IUCN Red List Near threatened species, that is endangered by habitat loss. [3] [1]
Libocedrus plumosa is an evergreen coniferous tree growing to 30–35 metres (98–115 ft) tall, with a trunk up to 3 metres (9.8 ft) diameter. The bark is loose, fibrous and light brown. [2]
The foliage is arranged in flattened sprays; the leaves are scale-like, arranged in opposite decussate pairs on the shoots; the facial leaves are 1–2 mm long and 1 mm broad, and the lateral leaves distinctly larger, 2–5 mm long and 1.5–2 mm broad.
The seed cones are cylindrical, 12–18 mm long, with four scales each with a prominent curved spine-like bract; they are arranged in two opposite decussate pairs around a small central columella; the outer pair of scales is small and sterile, the inner pair large, each bearing two winged seeds. They are mature about six to eight months after pollination. The pollen cones are 3–5 mm long. [3]
The kawaka has been planted as an ornamental tree in several parts of the British Isles, including as far north as Castlewellan, Northern Ireland. [4]
Chamaecyparis pisifera is a species of false cypress, native to central and southern Japan, on the islands of Honshū and Kyūshū.
Libocedrus is a genus of five species of coniferous trees in the cypress family Cupressaceae, native to New Zealand and New Caledonia. The genus is closely related to the South American genera Pilgerodendron and Austrocedrus, and the New Guinean genus Papuacedrus, both of which are included within Libocedrus by some botanists. These genera are rather similar to the Northern Hemisphere genera Calocedrus and Thuja: in earlier days, what is now Calocedrus was sometimes included in Libocedrus. They are much less closely related, as recently confirmed. The generic name means "teardrop cedar", apparently referring to drops of resin.
Austrocedrus is a genus of conifer belonging to the cypress family (Cupressaceae). It has only one species, Austrocedrus chilensis, native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude. It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar. The generic name means "southern cedar".
Juniperus californica, the California juniper, is a species of juniper native to southwestern North America.
Papuacedrus papuana is a species in the conifer family Cupressaceae, the sole species in the genus Papuacedrus. Some botanists do not consider this species as forming a distinct genus, but include it in the related genus Libocedrus. It is native to New Guinea and to the Indonesian Province of Maluku.
Juniperus occidentalis, known as the western juniper, is a shrub or tree native to the western United States, growing in mountains at altitudes of 800–3,000 metres (2,600–9,800 ft) and rarely down to 100 metres (330 ft). It is listed as Least Concern on the IUCN Red List because it is a widespread species with an increasing population.
Juniperus thurifera is a species of juniper native to the mountains of the western Mediterranean region, from southern France across eastern and central Spain to Morocco and locally in northern Algeria.
Calocedrus decurrens, with the common names incense cedar and California incense-cedar, is a species of conifer native to western North America. It is the most widely known species in the genus, and is often simply called 'incense cedar' without the regional qualifier.
Juniperus deppeana is a small to medium-sized tree reaching 10–15 m tall. It is native to central and northern Mexico and the southwestern United States. It grows at moderate altitudes of 750–2,700 meters (2,460–8,860 ft) on dry soils.
Juniperus flaccida is a large shrub or small tree reaching 5–10 m tall. It is native to central and northern Mexico and the extreme southwest of Texas, United States. It grows at moderate altitudes of 800-2,600 m, on dry soils.
Calocedrus formosana is a conifer endemic to Taiwan.
Calocedrus macrolepis is a conifer native to southwest China, northern Vietnam, northern Laos, extreme northern Thailand and northeastern Myanmar.
Juniperus semiglobosa is a species of juniper native to the mountains of Central Asia, in northeastern Afghanistan, westernmost China (Xinjiang), northern Pakistan, southeastern Kazakhstan, Kyrgyzstan, western Nepal, northern Republic of India, Tajikistan, and Uzbekistan. It grows at altitudes of 1,550–4,350 metres (5,090–14,270 ft) .
Juniperus standleyi is a species of juniper native to Guatemala and the adjacent extreme southeast of Mexico, where it occurs at elevations of 3,000–4,250 m. Its local common names include huitó, cipres, and huitum.
Juniperus tibetica, the Tibetan juniper, is a species of juniper, native to western China in southern Gansu, southeastern Qinghai, Sichuan, and Tibet Autonomous Region, where it grows at high to very high altitudes of 2,600–4,800 metres (8,500–15,700 ft). This species may possess the highest elevation treeline in the world.
Libocedrus austrocaledonica is a species of Libocedrus, endemic to New Caledonia, occurring mainly in the southern half of the island, at 750–1,400 m altitude in montane cloud forest scrub.
Libocedrus bidwillii, also called pāhautea, kaikawaka or New Zealand cedar, is a species of Libocedrus, endemic to New Zealand. It is in the cypress family Cupressaceae.
Libocedrus chevalieri is a species of conifer in the cypress family, Cupressaceae. It is endemic to New Caledonia, occurring in three small, isolated populations on low mountain summits at 650–1,620 m altitude in cloud forest scrub on serpentine soils. It is threatened by habitat loss.
Libocedrus yateensis is a species of Libocedrus, endemic to New Caledonia, occurring in a few small, isolated populations in low altitude riverside sites at 150–600 m altitude in rainforest scrub. It is threatened by habitat loss.
Widdringtonia schwarzii is a species of Widdringtonia native to South Africa, where it is endemic to the Baviaanskloof and Kouga Mountains west of Port Elizabeth in Eastern Cape Province; it occurs on dry rocky slopes and crags at 600-1,200 m altitude. It is threatened by habitat loss, particularly by wildfire. The Willowmore cypress is a protected tree in South Africa.
