Lebronnecia is a monotypic genus of flowering plants in the family Malvaceae. [4] The sole species is Lebronnecia kokioides, a very rare flowering shrub.
Only a few hundred specimens are known to exist. The plant was first described in 1966, after a single tree with a few seedlings was discovered on Tahuata, an island in the Marquesas group of French Polynesia that had been severely deforested by livestock: cattle, goats, horses, and pigs.
Further specimens were later found on the nearby island of Mohotani, uninhabited by humans, but similarly deforested by sheep, who seem to avoid eating the plant. [5]
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within nine families. The order is placed in the eurosids II, which are part of the eudicots.
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao, roselle and durian. There are also some genera containing familiar ornamentals, such as Alcea (hollyhock), Malva (mallow), and Tilia. The genera with the largest numbers of species include Hibiscus, Pavonia, Sida, Ayenia, Dombeya, and Sterculia.
Hibiscus tiliaceus, commonly known as the sea hibiscus or coast cottonwood, is a species of flowering tree in the mallow family, Malvaceae, with a pantropical distribution along coastlines. It has also been introduced to Florida and New Zealand. It has been debated whether this species is native or introduced to Hawaii.
Jubaea is a genus of palms with one species, Jubaea chilensis, commonly known in English as the Chilean wine palm or Chile cocopalm, and palma chilena in Spanish. It is native to southwestern South America and is endemic to a small area of central Chile between 32°S and 35°S in southern Coquimbo, Valparaíso, Santiago, O'Higgins, and northern Maule regions.
Corypha umbraculifera, the talipot palm, is a species of palm native to eastern and southern India and Sri Lanka. It is also grown in Cambodia, Myanmar, Thailand and the Andaman Islands. It is one of the five accepted species in the genus Corypha. It is a flowering plant with the largest inflorescence in the world. It lives up to 60 years before bearing flowers and fruits. It dies shortly after.
Ravenea is a genus of 20 known species of palms, all native to Madagascar and the Comoros.
Barclaya is a genus of six species of flowering plants of the family Nymphaeaceae. Barclaya are aquatic plants native to tropical Asia. The genus was named in honour of the American-born English brewer and patron of science Robert Barclay.
The Saint Helena olive is an extinct species of flowering plant. It is the only member of the genus Nesiota. It was endemic to the island of Saint Helena in the South Atlantic Ocean. Despite its name, it is unrelated to the true olive, but is instead a member of the family Rhamnaceae, the family which contains buckthorns and jujube. The last remaining tree in the wild died in 1994, and the last remaining individual in cultivation died in December 2003, despite conservation efforts. It is thus a prime example of recent plant extinction. The Saint Helena olive belongs to the tribe Phyliceae, which are mostly endemic to Southern Africa.
Ayenia sparrei is a species of flowering plant in the family Malvaceae. It a shrub found only in Ecuador.
Dicellostyles axillaris is a species of flowering plant in the family Malvaceae endemic to Sri Lanka. It is the only species in the genus Dicellostyles.
Hibiscadelphus crucibracteatus is an extinct species of flowering plant in the family Malvaceae that was endemic to Hawaii, on the island of Lanai.
Hibiscadelphus woodii, or Wood's hau kuahiwi, is a species of flowering plant in the family Malvaceae endemic to Kauai, Hawaii.
Kokia lanceolata, the Wailupe Valley treecotton, was a species of flowering plant in the family Malvaceae. It was the only species of Kokia to occur on the island of Oahu and originally known from the hills of Makapu'u, Koko Head and Wailupe Valley. It became extinct not long after its discovery in the 1880s, most likely due to grazing pressure from cattle and goat ranching.
Sonchus brassicifolius, synonym Dendroseris litoralis, is a species of flowering plant in the daisy and sunflower family Asteraceae. It is a small evergreen tree species known as the cabbage tree. It is endemic to the Juan Fernández Islands, which lie in the southeast Pacific, off the west coast of Chile. It is native only to the tiny, volcanic Robinson Crusoe Island, home of the famed Juania australis and many other endemic plants. The species is threatened by habitat loss and has been brought back from the brink of extinction. It had been reduced to only a few individuals by feral goats on the island, and is still considered critically endangered.
Juania australis, the Chonta palm, is a species of flowering plant in the family Arecaceae, the only species in the genus Juania. It is a solitary trunked palm tree which is endemic to the Juan Fernández Islands archipelago in the southeast Pacific Ocean west of Chile.
Saribus jeanneneyi is a very rare species of palm tree in the genus Saribus. It is endemic to southern New Caledonia, where only one mature specimen, surrounded by a few seedlings, survived in its native habitat as of 1997. The cause of its rarity in the wild is because its meristem is edible.
Oxera is a genus of flowering plants in the family Lamiaceae native to Vanuatu and New Caledonia in the western Pacific.
Gossypieae is a tribe of the flowering plant subfamily Malvoideae. It includes the cotton (Gossypium) and related plants. It is distinguished from the Hibisceae on the basis of embryo structure and its apparently unique possession of glands able to synthesize the pigment gossypol.
Cephalohibiscus peekelii is a species of flowering plant belonging to the family Malvaceae. It is a tree native to New Guinea, the Bismarck Archipelago, and the Solomon Islands. It is the sole species in genus Cephalohibiscus. It grows in lowland rain forests from sea level to 600 meters elevation.
Hafotra superba is a species of flowering plant in the family Malvaceae. It is the sole member of genus Hafotra. It is a shrub or small tree endemic to central Madagascar. It grows 3 to 4 meters tall.
