Catharanthus is a genus of flowering plants in the dogbane family, Apocynaceae. Like genus Vinca, they are known commonly as periwinkles. There are eight known species. Seven are endemic to Madagascar, though one, C. roseus, is widely naturalized around the world. The eighth species, C. pusillus, is native to India and Sri Lanka. The name Catharanthus comes from the Greek for "pure flower".
Apocynum, commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek ἀπόκυνον apókunon, from ἀπο- apo- "away" and κύων kúōn "dog", referring to dogbane, which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe.
Periwinkle is a color in the blue and violet family. Its name is derived from the lesser periwinkle or myrtle herb which bears flowers of the same color.
Nerium oleander is a shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as nerium or oleander, from its superficial resemblance to the unrelated olive Olea. It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco may have taken its name from the Berber name alili or oualilt for the flower. Oleander is one of the most poisonous commonly grown garden plants.
Apocynum cannabinum is a perennial herbaceous plant that grows throughout much of North America - in the southern half of Canada and throughout the United States. It is a poisonous plant: Apocynum means "poisonous to dogs". All parts of the plant are poisonous and can cause cardiac arrest if ingested. However, some Lepidoptera feed on this plant, such as two hummingbird moths. The specific epithet cannabinum and the common names hemp dogbane and Indian hemp refer to its similarity to Cannabis as a fiber plant, rather than as a source of a psychoactive drug.
Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a species of flowering plant in the dogbane family Apocynaceae. It is native and endemic to Madagascar, but grown elsewhere as an ornamental and medicinal plant, a source of the drugs vincristine and vinblastine, used to treat cancer. It was formerly included in the genus Vinca as Vinca rosea.
Aphis nerii is an aphid of the family Aphididae. Its common names include oleander aphid, milkweed aphid, sweet pepper aphid, and nerium aphid.
Apocynum venetum, commonly known as sword-leaf dogbane, is a plant species in the dogbane family, poisonous but used as a source of fiber, medicine, and nectar for production of honey. Apocynum venetum leaves have been used in the traditional medicine for hypertension treatment.
