Gomortega keule (syn. G. nitida; Spanish names keule, queule, and hualhual) is a species of tree endemic to Chile. It is the sole species of the genus Gomortega and, according to the APG IV system of 2016 (unchanged from the APG systems of 2009, 2003 and 1998), of the monotypic family Gomortegaceae, assigned to the order Laurales in the clade magnoliids. [3]
Evergreen trees, aromatic, gray bark with shallow longitudinal fissures. The leaves are petiolate, simple, entire, obovate to lanceolate, coriaceous. The stems have unilacunar nodes and with two foliar traces. The branches are quadrangular.
The edible fruit is a uni- or tri-locular yellow drupe, usually with 1 (-2) seeds, fleshy mesocarp, pleasant, stony endocarp. There are 1-2 seeds per fruit, with abundant, oily endosperm, large embryo, dicotyledonous. The fruit is about 34–45 millimetres (1.3–1.8 in) in diameter and edible and sweet, and harvested for making a kind of marmalade.
The chromosome number is n = 21, 2n = 42.
Gomortega keule grows only in a very narrow habitat range in coastal Central Chile, including the Maulino forest [4] and parts of the Chilean matorral. [5] It is a characteristic tree species of the Maulino forest alongside Nothofagus glauca , Nothofagus × leoni, and Nothofagus alessandrii . [4]
The species is threatened by habitat loss. The Maulino forest has mostly been cleared for agriculture and tree plantations of Pinus radiata and Eucalyptus globulus . The species' remaining habitat is fragmented, and its populations isolated. It has been affected by fires, including the 2017 Chile wildfires. Populations are protected at Los Queules National Reserve and Los Ruiles National Reserve. [1]
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae. The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta.
Ceratophyllaceae is a cosmopolitan family of flowering plants including one living genus commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant family in the order Ceratophyllales. Species are commonly called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
Amborella is a monotypic genus of understory shrubs or small trees endemic to the main island, Grande Terre, of New Caledonia in the southwest Pacific Ocean. The genus is the only member of the family Amborellaceae and the order Amborellales and contains a single species, Amborella trichopoda. Amborella is of great interest to plant systematists because molecular phylogenetic analyses consistently place it as the sister group to all other flowering plants, meaning it was the earliest group to evolve separately from all other flowering plants.
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and Argentina. It is part of the Neotropical realm. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common.
Petrosaviaceae is a family of flowering plants belonging to a monotypic order, Petrosaviales. Petrosaviales are monocots, and are grouped within the lilioid monocots. Petrosaviales is a very small order composed of one family, two genera and four species accepted in 2016. Some species are photosynthetic (Japonolirion) and others are rare, leafless, chlorophyllous, mycoheterotrophic plants (Petrosavia). The family is found in low-light montane rainforests in Japan, China, Southeast Asia and Borneo. They are characterised by having bracteate racemes, pedicellate flowers, six persistent tepals, septal nectaries, three almost-distinct carpels, simultaneous microsporogenesis, monosulcate pollen, and follicular fruit.
Aextoxicon is a genus of dioecious trees native to southern Chile and Argentina. It is the only genus in the monotypic family Aextoxicaceae, and is itself represented by the olivillo. It is a large evergreen tree native to the forests of the Valdivian temperate rain forests and Magellanic subpolar forests of the Pacific coast of southern Chile, where it forms is a canopy tree in the broadleaf forests. It can reach 15 m tall.
The Berberidaceae are a family of 18 genera of flowering plants commonly called the barberry family. This family is in the order Ranunculales. The family contains about 700 known species, of which the majority are in the genus Berberis. The species include trees, shrubs and perennial herbaceous plants.
Ticodendron incognitum is the only species of Ticodendron, and the only member of the family Ticodendraceae. It is most closely related to the family Betulaceae.
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade. Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades, the common sunflower, petunias, yacon, morning glory, lettuce, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, blueberries, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut.
The Hernandiaceae are a family of flowering plants (angiosperms) in the order Laurales. Consisting of five genera with about 58 known species, they are distributed over the world's tropical areas, some of them widely distributed in coastal areas, but they occur from sea level to over 2000 m.
Juncaginaceae is a family of flowering plants, recognized by most taxonomists for the past few decades. It is also known as the arrowgrass family. It includes 3 genera with a total of 34 known species.
Hypoxidaceae is a family of flowering plants, placed in the order Asparagales of the monocots.
Euptelea is a genus of two species of flowering plants in the monogeneric family Eupteleaceae. The genus is found from Assam east through China to Japan, and consists of shrubs or small trees:
Nothofagus alessandrii, the ruil, is a species of plant in the family Nothofagaceae, commonly known as the southern beeches. It is endemic to Chile, occurring chiefly in the Chilean matorral ecoregion. It is threatened by habitat loss. The species is protected within Los Ruiles National Reserve.
Nothofagus glauca, commonly known as hualo or roble Maulino, is a species of plant in the family Nothofagaceae. It is a deciduous tree endemic to Chile. It grows from 34° to 37° South latitude. It is a typical tree of the maritime mediterranean-climate Maulino forest of Central Chile, its current range spanning over 330 km from north to south. The species grows on a variety of soils and is mostly found on gentle to steep slopes.
Pitavia punctata is a species of tree endemic to Chile in the family Rutaceae. It is known by the common names Pitao and Pitran. It grows in native deciduous forests in the Chilean Coast Range of central Chile. It is threatened with habitat loss, and is assessed as Endangered.
Citronella mucronata, the huillipatagua, naranjillo, or Chilean citronella tree, is an evergreen tree endemic to Chile. It grows in the Chilean matorral region of central Chile from 30º to 40° south latitude.
The Chilean Matorral (NT1201) is a terrestrial ecoregion of central Chile, located on the west coast of South America. It is in the Mediterranean forests, woodlands, and scrub biome, part of the Neotropical realm.
Los Queules National Reserve is a national reserve of Chile. It covers an area of 1.47 km2 in the Chilean Coastal Range. The reserve ranges from 400 to 500 meters in elevation.
Maulino forest is a forest type naturally growing in the Chilean Coast Range of Central Chile from latitude 35°55 to 36°20 S. The forest grows in the transition zone between Mediterranean climate and humid temperate climate. Precipitation varies from 1000 to 700 mm/a and is concentrated in winter. According to geographers Humberto Fuenzalida and Edmundo Pisano the forest is one of mesophytes on the transition zone of temperate rain forests.
