Pseudohydrosme gabunensis, commonly known as the Gabon false hydrosme, is a species of flowering plant in the family Araceae. It was described by Heinrich Gustav Adolf Engler in 1892. [1]
Pseudohydrosme gabunensis on average reaches about 15 cm (5.90 inches) tall, and 9–12 cm (3.54-4.72 inches) in diameter. Leaves are 1-1.3 m (3.28-4.26 inches) long, and 1-1.4 m (3.28-4.59 feet) in diameter. Spathe is 30–55 cm (11.81-21.65 inches) long. Flowers are white on the outside, to a purple-black color in the inside. Seeds are 9 mm (0.35 inches) long, and 7 mm (0.27 inches) wide. [2]
Pseudohydrosme gabunensis is endemic to the surrounding areas, and within Libreville, Gabon, where it grows in lowland tropical rainforests. Specimens are only known from five recorded sites, four being within Libreville, and the other being in the Komo Department, Gabon. [2]
Pseudohydrosme gabunensis is spelt in its Latin name as "gabunensis" or "Gabun", which is the German spelling of Gabon. [2]
Pseudohydrosme gabunensis is currently listed as "Endangered" by the IUCN Red List, for deforestation and poaching are affecting the species limited natural range greatly. The species has gone extinct in some of its native range, for human urbanization and development are also becoming a severe threat in Libreville and some other surrounding suburban areas. [3]
Pseudohydrosme gabunensis is being over-exploited as an ornamental plant, from which collectors are trying to make a profit on the illegal plant trade, or keeping the specimens for themselves, being very similar to Pseudohydrosme ebo . [2]
Quercus georgiana, the Georgia oak or Stone Mountain oak, is a rare deciduous red oak, native to the southeastern United States.
Nepenthes sibuyanensis is a tropical pitcher plant endemic to Sibuyan Island in the Philippines, after which it is named.
Nepenthes edwardsiana, or the splendid pitcher-plant, is a carnivorous tropical pitcher plant endemic to Mount Kinabalu and neighbouring Mount Tambuyukon in Sabah, Malaysian Borneo. It is considered one of the most spectacular of all Nepenthes, producing some of the largest pitchers and the most highly developed peristome ribs of any species in the genus.
Nepenthes klossii is a tropical pitcher plant endemic to New Guinea.
Nepenthes hispida is a tropical pitcher plant species native to Borneo. It grows at elevations of 100 to 800 m in kerangas forest. It is known with certainty only from Lambir Hills National Park and surrounding areas.
Nepenthes aristolochioides is a tropical pitcher plant endemic to Sumatra, where it grows at elevations of 1800–2500 m above sea level. It has an extremely unusual pitcher morphology, having an almost vertical opening to its traps. It is critically endangered by overcollection.
Nepenthes bellii is a tropical pitcher plant endemic to the Philippine islands of Mindanao and Dinagat, where it grows at elevations of 0–800 m above sea level.
Nepenthes dubia is a tropical pitcher plant endemic to the Indonesian island of Sumatra, where it grows at an altitude of 1600–2700 m above sea level. The specific epithet dubia is the Latin word for "doubtful".
Nepenthes talangensis is a tropical pitcher plant endemic to Sumatra, where it grows in upper montane forest at elevations of 1800–2500 m above sea level.
Nepenthes tenuis is a tropical pitcher plant endemic to the Indonesian island of Sumatra. The species was first collected in 1957, from a remote mountain in the western part of the island. It remained undescribed until 1994, and was only rediscovered in the wild in 2002. Prior to this, N. tenuis was known solely from a single photograph and dried herbarium specimen.
Nepenthes rigidifolia is a critically endangered tropical pitcher plant endemic to Sumatra, where it grows at elevations of 1000–1600 m above sea level.
Nepenthes mikei is a tropical pitcher plant endemic to Sumatra. It is characterised by its black mottled lower and upper pitchers. The species is closely related to N. angasanensis and N. tobaica.
Pseudohydrosme is a genus of flowering plants in the family Araceae. It contains only three species, Pseudohydrosme buettneri, Pseudohydrosme gabunensis, and more recently Pseudohydrosme ebo, two being endemic to tropical rain forests in Gabon, and the other being native to the Ebo Forest of Cameroon. The genus is believed to be closely related to Anchomanes and is likely to be sunk into Anchomanes due to molecular evidence.
Hypodaphnis is a monotypic genus of flowering plants of the family Lauraceae. Its only extant species, Hypodaphnis zenkeri, is native to Gabon. Although only one living species is known, fossils of some species of this genus are present in North America, especially in Northern Mexico. In most phylogenetic analysis, Hypodaphnis appears as the basal branch, the sister group of the rest of the family Lauraceae.
Nepenthes abgracilis is a tropical pitcher plant native to the Philippines. It is known only from northeastern Mindanao, including Mount Legaspi. Little is known about the altitudinal distribution of this species, but the holotype was collected at 670 m.
Encephalartos latifrons is a species of cycad that is native to Eastern Cape province in South Africa at elevations of 200 and 600 metres.
Encephalartos tegulaneus, the Kenyan giant cycad, is a species of cycad endemic to Kenya. It occurs in Eastern Province near Embu, Kenya, and on the Matthews Range in Rift Valley Province.
Uvariopsis dicaprio is a species of tropical evergreen tree in the genus Uvariopsis. It is endemic to the Ebo Forest, in the Littoral Region of Cameroon. It was the first new plant species described in 2022, and was named after American actor Leonardo DiCaprio by botanists Martin Cheek and George Gosline, from the Royal Botanic Gardens, Kew. U. dicaprio is classified as Critically Endangered in the IUCN Red List.
Pseudohydrosme ebo, commonly known as the Ebo false hydrosme, is a species of flowering plant in the family Araceae. It was described by Xander Van der Burgt in 2015, but was not officially classified as a true species in the genus Pseudohydrosme until 2018.
Pseudohydrosme buettneri, commonly known as Büttner's false hydrosme, is a species of flowering plant in the family Araceae. It was described by Adolf Engler in 1892.
