Secamonoideae is a subfamily of the dogbane family, Apocynaceae. [1]
Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
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.
Sarcostemma is a genus of flowering plants in the dogbane family, Apocynaceae, first described as a genus in 1810. The name is derived from the Greek words σαρκὸς (sarkos), meaning "flesh," and στέμμα (stemma), meaning "garland". Members of the genus are known generally as climbing milkweeds or caustic bushes. They are found across Africa and tropical Asia, in Australia, and in parts of North America. These plants are perennial flowering shrubs with trailing vines or lianas. They are often adapted to heat and/or desert conditions. Some have few or no leaves and photosynthesize in the tissues of the green stems. The soft stems are filled with a milky white latex that is poisonous and caustic in some species. The flowers have a ring of thick tissue at the base which extends into hollow spherical appendages within the flower corolla.
Rauvolfioideae is a subfamily of the flowering plant family Apocynaceae. Many species are woody lianas, others are shrubs or perennial herbs.
