Ravenea moorei is a species of palm tree. It is endemic to the Comoros. This species is critically endangered, with only two mature specimens last noted in 1993. [1]
The Haast's eagle is an extinct species of eagle that once lived in the South Island of New Zealand, commonly accepted to be the pouakai of Maori legend. It was the largest eagle known to have existed, with an estimated weight of 15 kilograms (33 lb) nearly double that of the harpy eagle at 9 kilograms (20 lb). Its massive size is explained as an evolutionary response to the size of its prey, the flightless moa, the largest of which could weigh 230 kg (510 lb). Haast's eagle became extinct around 1400, after the moa were hunted to extinction by the first Māori.
Crinum is a genus of about 180 species of perennial plants that have large showy flowers on leafless stems, and develop from bulbs. They are found in seasonally moist areas, including marshes, swamps, depressions and along the sides of streams and lakes in tropical and subtropical areas worldwide.
Ravenea is a genus of 20 known species of palms, all native to Madagascar and the Comoros.
The motorbike frog is a ground-dwelling tree frog of the family Pelodryadidae found in Southwest Australia. Its common name is derived from the male frog's mating call, which sounds similar to a motorbike changing up through gears; it is also known as Moore's frog, the western bell frog, western green and golden bell frog, and western green tree frog.
Ravenea albicans is a species of flowering plant in the Arecaceae family. It is a palm endemic to northeast Madagascar and found in seven fragmented locations between the towns of Ampasimanolotra and Antalaha with the exception of one location much farther south near Vondrozo. It is an endangered species threatened by habitat loss. There are perhaps 200 mature individuals remaining. In its natural range it tends to grow in humid forests within northeast Madagascar's mountain valleys. It is unique among the Ravenea genus because its pinnate leaves have an exotic, colorful appearance. Its species name, albicans, is derived from the Latin word for the color white, album, as is the word for albinism. The base of each frond is green, yet they become white to dark grey near the tip at maturity. Some individuals have completely white fronds.
Ravenea dransfieldii is a species of flowering plant in the family Arecaceae. It is found only in Madagascar. It is threatened by habitat loss.
Ravenea hildebrandtii is a species of palm tree. It is endemic to the Comoros. It is threatened by habitat loss.
Ravenea julietiae is a species of flowering plant in the Arecaceae family. It is a palm endemic to Madagascar. It is threatened by habitat loss, and there are perhaps 80 mature individuals remaining in the wild.
Ravenea lakatra is a species of flowering plant in the Arecaceae family. It is a palm endemic to Madagascar. It is threatened by habitat loss and overcollection. There are probably fewer than 30 mature plants remaining in the wild.
Ravenea latisecta is a species of flowering plant in the family Arecaceae.
Ravenea louvelii is a species of flowering plant in the Arecaceae family. It is a palm endemic to Madagascar, where it is known from a single location. There are fewer than 10 individuals left. They are believed to be in Andasibe-Mantadia National Park on the Western margin of central Madagascar. They are protected by restriction of access to the location.
Ravenea musicalis, or the river palm, is a species of flowering plant in the family Arecaceae. Also known by the Antanosy word "torendriky," meaning "submerged trunk", R. musicalis is known for being the only truly aquatic palm tree. Like many mangrove trees, R. musicalis seeds germinate within the fruit, and the seedling takes root underwater. Endemic to Madagascar, R. musicalis was first discovered in 1993 by Henk Beentje on an expedition funded by the McDonald's restaurant. This palm is listed in the IUCN Red List. This tree is harvested by local people primarily for building material and food. Over-harvesting, habitat degradation and habitat loss threaten the remaining populations. Horticulturalists prize R. musicalis for its rarity and unique life history.
Ravenea nana is a species of flowering plant in the Arecaceae. It is a palm endemic to Madagascar. It is known from only four locations with a total population of about 100 individuals.
Ravenea rivularis, the majestic palm, or majesty palm, is a species of tree in the family Arecaceae. While often marketed in stores as a "plant" in a pot, in its natural state, the majesty palm grows to 98 feet tall.
Ravenea xerophila is a solitary medium-sized palm in the family Arecaceae. It is found only in southern Madagascar, and is threatened by habitat loss. Trees grow from 1.5–8 meters in height, and 13–30 cm in diameter.
Haramiyidans were a long lived lineage of mammaliaform cynodonts or mammals. Their teeth, which are by far the most common remains, resemble those of the multituberculates. However, based on Haramiyavia, the jaw is less derived; and at the level of evolution of earlier basal mammals like Morganucodon and Kuehneotherium, with a groove for ear ossicles on the dentary. If they are early multituberculates, they would be the longest lived mammalian clade of all time. However, a more recent study, in November 2015, may dispute this and suggested the Haramiyida were not crown mammals, but were part of an earlier offshoot of mammaliaformes instead.
Drosera moorei is a scrambling or climbing perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and grows near granite outcrops in sandy loam. D. moorei produces small, circular, peltate carnivorous leaves along glabrous stems that can be 12–35 cm (5–14 in) long. Inflorescences have two to ten yellow flowers and bloom from September to October.
Cucurbita moorei is a plant species of the genus Cucurbita. It is native to the vicinity of Ixmiquilpan, Mexico. It has dark green leaves with white markings and orange flowers.
Ravenea beentjei is a species of palm tree. It is endemic to Madagascar, where it grows in a frequently flooded area within a single locality of southeast Madagascar called Vondrozo. There are only about 40 mature trees known in their natural range. Like the majority of species in the Ravenea genus, it requires ample freshwater to survive. Therefore, it grows in valleys and swampy areas within the lowland tropical and subtropical moist broadleaf forests that carpet eastern Madagascar.
Natalie Whitford Uhl (1919–2017) was an American botanist who specialised in palms.
