Rubia is the type genus of the Rubiaceae family of flowering plants, which also contains coffee. It contains around 80 species of perennial scrambling or climbing herbs and subshrubs native to the Old World. The genus and its best-known species are commonly known as madder, e.g. Rubia tinctorum, Rubia peregrina, and Rubia cordifolia.
The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, they were treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family.
Alyxia is an Australasian genus of flowering plant in the dogbane family, Apocynaceae. It contains at present 106 species, but Alyxia stellata and A. tisserantii are very variable, might be cryptic species complexes, and are need of further study. It consists of shrubby, climbing or scrambling plants. This genus occurs in China, the Himalayas, Southeast Asia, Australia, New Caledonia and the Pacific Islands. There are 14 species in Australia, 21 in New Caledonia and 7 in the other Pacific Islands, including Hawaiʻi.
Aeschynanthus is a genus of about 150 species of evergreen subtropical and tropical plants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno and anthos (flower). The common name for some species is lipstick plant, which comes from the appearance of the developing buds emerging from the calyces. A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
Cynanchum is a genus of about 300 species including some swallowworts, belonging to the family Apocynaceae. The taxon name comes from Greek kynos and anchein, hence the common name for several species is dog-strangling vine. Most species are non-succulent climbers or twiners. There is some evidence of toxicity.
Stephanotis is a genus of flowering plants first described in 1806. The name derives from the Greek stephanōtís fit for a crown, derivative of stéphanos (masculine) crown. It contains evergreen, woody-stemmed lianas with a scattered distribution in several tropical and subtropical regions.
Pergularia is a genus of the botanical family Apocynaceae. Pergularia daemia is a perennial twinning herb that grows along the roadsides of India and tropical and subtropical regions in South Asia, Africa, and Australia.
Oxypetalum is a genus of flowering plants in the family Apocynaceae, first described with this name in 1810. The genus is native to South America.
Dischidia is a genus of plants in the “dog-bane” family Apocynaceae, collectively known as the “milkweeds”. They are epiphytes, native to tropical areas of China, India as well as Bhutan’s southern borders, wherever minimal frost occurs. Additionally, they are known from most areas of Indo-China, including forested areas of Myanmar, Thailand, Vietnam, Cambodia, Laos, and some parts of Malaysia and Singapore.
Vincetoxicum is a genus of plants in the family Apocynaceae. Although the species in Vincetoxicum have sometimes been included in Cynanchum, chemical and molecular evidence shows that Vincetoxicum is more closely related to Tylophora, now included in Vincetoxicum. The generic name means "poison-beater" in Botanical Latin because of the plants' supposed antidotal effects against snakebite.
Funastrum is a genus of flowering plant now in the family Apocynaceae. The name is derived from the Latin word funis, meaning "rope", and astrum, alluding to the twining stems. Members of the genus are commonly known as twinevines.
Dregea is a genus of vines in the Apocynaceae, established by Ernst Meyer in 1838. It is native to southern Africa, Yemen and eastern Asia from China to Sulawesi.
Gongronema is a genus of plants first described as a genus in 1844. Some of the species are native to Africa, with others in South and Southeast Asia.
Heterostemma is a genus of plants in the family Apocynaceae, first described in 1834. It is native to India, China, Taiwan, Southeast Asia, Australia, and certain islands in the Pacific.
Pachycarpus is a genus of plants in the family Apocynaceae, first described in 1838. It is native to Africa.
Pentatropis is a genus of plants in the family Apocynaceae, first described as a genus in 1834. It is native to Africa and southern Asia.
Ruehssia is a genus of plants in the family Apocynaceae. It is also in the Asclepiadoideae subfamily and Marsdenieae tribe.
