| Megistostegium perrieri | |
Megistostegium perrieri is a plant in the family Malvaceae. It is endemic to Madagascar.
Megistostegium perrieri grows as a shrub up to 1 metre (3 ft 3 in) tall. Its large leaves are orbicular to round in shape. They are coloured gray-green and measure up to 5.4 cm (2 in) long. The flowers are pendant with an epicalyx that matures to a deep maroon colour. The pollen is yellow when fresh. [2]
Megistostegium perrieri is found only on the coastline of the Mahafaly Plateau of southern Madagascar, including in the Special Reserve at Cape Sainte Marie. [2] Its habitat is in rocky areas from sea level to about 500 m (1,600 ft) altitude. [1] [2]
Threats to Megistostegium in general include grazing by goats and invasive plants competing for limited water supplies. The pollinator of M. perrieri may be extinct. The preliminary conservation status of the species is Endangered. [2]
The leaves of M. perrieri are locally used to treat coughs. The branches are sometimes used for decorative purposes. [2]
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots.
Buxus is a genus of about 70 species in the family Buxaceae. Common names include box or boxwood.
Adansonia is a genus made up of eight species of medium to large deciduous trees known as baobabs. Previously classified within the family Bombacaceae, they are now placed in the Malvaceae. They are native to Madagascar, mainland Africa and Australia. Trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described Adansonia digitata. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The flowers open around dusk; opening so quickly that movement can be detected by the naked eye and are faded by the next morning. The fruits are large, oval to round and berry-like and hold kidney-shaped seeds in a dry, pulpy matrix.
Takhtajania is a genus of flowering plants of the family Winteraceae, which contains a single species, Takhtajania perrieri. It is endemic to Madagascar.
Adansonia za is a species of baobab in the genus Adansonia of the family Malvaceae. It was originally named in French as anadzahé. Common names in Malagasy include bojy, boringy, bozy, bozybe, ringy, and za, the last of which gives the plant its specific epithet. Eight Adansonia species are recognized, with six endemic to Madagascar. Adansonia za is the most widespread of the Madagascar endemics.
Analamerana Special Reserve is a 347 square kilometres (134 sq mi) wildlife reserve in the north of Madagascar. The reserve was created in 1956 to protect its endemic plants and animals, such as the critically endangered Perrier's sifaka, which is considered to be one of the most endangered primates in the world.
Anjanaharibe-Sud Reserve is a wildlife reserve in the north-east of Madagascar. The reserve was designated in 1958 and contains some of the last intact primary rainforest, along with several, rare and endemic animals and plants. The area was nominated to the UNESCO Tentative List of World Heritage Sites in Madagascar in 2008, as an extension of the rainforests of the Atsinanana.
Perrier's sifaka is a lemur endemic to Madagascar. It was formerly considered to be a subspecies of diademed sifaka It has a very small range in northeastern Madagascar where its habitat is dry deciduous or semihumid forest. Part of its range is in protected areas. It is an almost entirely black sifaka and measures about 90 cm (35 in), half of which is a bushy tail. Females are slightly larger than males.
Abelmoschus ficulneus is a species of flowering plant in the genus Abelmoschus, family Malvaceae. Commonly known as white wild musk mallow or native rosella, it is fibrous perennial with a woody stem. Its flowers are about an inch in diameter, either pink or white, with a rose center; its leaves are palmate.
Aspidostemon is a genus of flowering plants belonging to the family Lauraceae. It is present from Madagascar.
The flora of Madagascar consists of more than 12,000 species of plants, as well as a poorly known number of fungi and algae. Around 83% of Madagascar's vascular plants are found only on the island. These endemics include five plant families, 85% of the over 900 orchid species, around 200 species of palms, and such emblematic species as the traveller's tree, six species of baobab and the Madagascar periwinkle. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic, 150–160 and 84–91 million years ago, respectively. However, few plant lineages remain from the ancient Gondwanan flora; most extant plant groups immigrated via across-ocean dispersal well after continental break-up.
Iris perrieri is a plant species in the genus Iris; it is also in the subgenus Iris. It is a rhizomatous perennial, from the Savoy Alps in southern France and recently in Italy. It has green, deeply ribbed, sickle shaped leaves, a slender stem with a branch, 1–3 scented flowers that are violet or purple, with a white or pale blue beard. It is rarely cultivated as an ornamental plant in temperate regions, due to its rarity in the wild. It was once thought to be a form of Iris aphylla, before cell (chromosome) analysis determined it to be a separate species.
Sartidia perrieri is a grass species endemic to Madagascar, known from only one collected individual and now considered extinct.
Rhopalocarpus mollis is a tree in the family Sphaerosepalaceae. It is endemic to Madagascar. The specific epithet mollis is from the Latin meaning "soft", referring to the very soft indumentum on the leaves' underside.
Pentachlaena vestita is a plant in the family Sarcolaenaceae. It is endemic to Madagascar. The specific epithet vestita is from the Latin meaning "blanketed", referring to the hairy indument on the underside of the leaves and also on stems, fruits and other surfaces.
Perrierodendron quartzitorum is a plant in the family Sarcolaenaceae. It is endemic to Madagascar.
Megistostegium is a genus of trees and shrubs in the family Malvaceae. The species are all endemic to Madagascar. The genus is threatened by livestock grazing, invasive plants and threats to pollinators.
Megistostegium microphyllum is a plant in the family Malvaceae. It is endemic to Madagascar.
Megistostegium nodulosum is a tree in the family Malvaceae. It is endemic to Madagascar.
Melhania dehnhardtii is a plant in the family Malvaceae. It is named for the German explorers Clemens and Gustav Denhardt.
