Rubiaceae is a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, ornamental cultivars, and historically some dye plants.
Kanaloa kahoolawensis, the Ka palupalu o Kanaloa or kohe malama malama o kanaloa, is a species of flowering plant in the legume family, Fabaceae and is endemic to Hawaii. Kanaloa is a monotypic genus with the single species Kanaloa kahoolawensis.
Psychotria viridis, also known as chacruna, chacrona, or chaqruy in the Quechua languages, is a perennial, shrubby flowering plant in the coffee family Rubiaceae. It is a close relative of Psychotria carthagenensis of Ecuador. It is commonly used as an ingredient of ayahuasca, a decoction with a long history of its entheogenic use and its status as a "plant teacher" among the Indigenous peoples of the Amazon rainforest.
Ziziphus mauritiana, also known as Indian jujube, Indian plum, Chinese date, Chinee apple, ber and dunks is a tropical fruit tree species belonging to the family Rhamnaceae. It is often confused with the closely related Chinese jujube, but whereas Z. jujuba prefers temperate climates, Z. mauritiana is tropical to subtropical.
Maianthemum trifolium is a species of flowering plant that is associated with extremely wet environments and is native to Canada and the northeastern United States as well as St. Pierre and Miquelon and Asia (Siberia).
Nepenthes sibuyanensis is a tropical pitcher plant endemic to Sibuyan Island in the Philippines, after which it is named.
Kleinhovia hospita is an evergreen, tropical tree native to Indonesia, Malaysia and other parts of tropical Asia and the Pacific. It is monotypic, being the only species in the genus Kleinhovia.
Nepenthes mantalingajanensis is a tropical pitcher plant known only from the summit region of Mount Mantalingajan, the highest point on the Philippine island of Palawan, after which it is named.
Nepenthes attenboroughii, or Attenborough's pitcher plant, is a montane species of carnivorous pitcher plant of the genus Nepenthes. It is named after the celebrated broadcaster and naturalist Sir David Attenborough, who is a keen enthusiast of the genus. The species is characterised by its large and distinctive bell-shaped lower and upper pitchers and narrow, upright lid. The type specimen of N. attenboroughii was collected on the summit of Mount Victoria, an ultramafic mountain in central Palawan, the Philippines.
Atractocarpus chartaceus, commonly known as the narrow-leaved gardenia, is a species of evergreen flowering plant in the madder and coffee family Rubiaceae. It is mostly found in subtropical rainforest of eastern Australia, and it is cultivated for its fragrant flowers and colourful fruit.
Nauclea orientalis is a species of tree in the family Rubiaceae, native to Southeast Asia, New Guinea, and Australia. It has many common names, including bur tree, canary wood, Leichhardt pine and yellow cheesewood. It grows to a maximum of around 30 m (98 ft) in height and has large glossy leaves. It bears spherical clusters of fragrant flowers that develop into golf ball-sized edible but bitter fruits. The yellowish to orange soft wood is also used for timber and in woodcarving and folk medicine.
Nepenthes robcantleyi, or Robert Cantley's pitcher plant, is a tropical pitcher plant endemic to the Philippine island of Mindanao. It is closely allied to N. truncata and was once considered a dark, highland form of this species. Nepenthes veitchii from Borneo is also thought to be a close relative.
Artocarpus camansi, the breadnut, is a species of medium-sized tree in the family Moraceae. It is native to New Guinea, the Maluku Islands, and the Philippines. It is the wild ancestor of the breadfruit (Artocarpus altilis) and is also sometimes known as the seeded breadfruit, to distinguish it from its mostly seedless descendant. Breadnut fruits are edible when cooked. The large seeds can also be roasted and eaten.
Brassica elongata, the elongated mustard or long-stalked rape, is a species of the mustard plant that is native to parts of Central Europe, Eastern Europe, the Balkan Peninsula, the Caucasus, Morocco and parts of Central Asia. Through plant invasion this species has become naturalized in many other parts of the world. Some of these naturalized regions include South Africa, North Western Europe, Australia and North America. Given the wide range of climate and ecological conditions of these regions, B. elongata has been able to disrupt the ecosystems of their native plant habitats and has been label as an invasive species in many of its naturalized zones. In North America, this species is often found as a roadside weed in the southwestern states, particularly in the state of Nevada. Studies allude that the Cruciferae might have migrated through the Bering land bridge from what is now Central Asia. Commonly known as the long-stalked rape or as langtraubiger Kohl in German, this species is a close cousin to Brassica napus (rapeseed) and a secondary genetic relative to B. oleracea (kale). As a close genetic species of the rapeseed, the long-stalked rape has one of the highest counts of accumulated polyunsaturated linoleic and linolenic acid. Both compounds are heavily used to manufacture vegetable oils. Brassica elongata has the propagative potential of turning into a horticultural product from what is currently a noxious weed.
The micrantha is a wild citrus from the papeda group, native to southern Philippines, particularly islands of Cebu and Bohol. Two varieties are recognized: small-flowered papeda, locally known as biasong, and small-fruited papeda or samuyao.
Mallotus tetracoccus, also known as the rusty kamala, is a species of flowering plant in the family Euphorbiaceae. It is a tree species found in parts of south Asia, typically occurring in the edges of tropical wet evergreen and semi-evergreen forests.
Dipterocarpus bourdillonii is a species of large tree in the family Dipterocarpaceae endemic to the Western Ghats principally in the state of Kerala in India. It is a Critically Endangered species according to the IUCN Red List of Threatened Species. It is a characteristic tree of the low-elevation tropical wet evergreen rainforests in the Western Ghats.
Saurauia whitfordii is a species of plant in the Actinidiaceae family. It is native to the Philippines. Elmer Drew Merrill, the American botanist who first formally described the species, named it after Harry Nichols Whitford, another American botanist who collected the specimen Merrill examined.
Discospermum philippinensis is an endemic species of genus Discospermum, which are flowering plants in the family Rubiaceae. The species was described in 2015, and was found on Mt. Banahaw, Tayabas, Quezon Province, Philippines at an elevation of 623 m. This species closely resemble that of D. whitfordii because of its persistent calyx, and prominent disk below the fruit apex. However, the species differs from D. whitfordii due to leaf blades with a much larger dimensions, the leaf apex of which are acute to attenuate, the fruits of which are faintly ribbed, with the thin mesocarp that are smaller, and fewer seeds per locule.
Myristica insipida, commonly known in Australia as Australian nutmeg, Queensland nutmeg or native nutmeg, is a small rainforest tree in the family Myristicaceae native to parts of Malesia, Papuasia and Australia. It is closely related to the commercially-important species of nutmeg, M. fragrans.
