Myrica is a genus of about 35–50 species of small trees and shrubs in the family Myricaceae, order Fagales. The genus has a wide distribution, including Africa, Asia, Europe, North America and South America, and missing only from Australia. Some botanists split the genus into two genera on the basis of the catkin and fruit structure, restricting Myrica to a few species, and treating the others in Morella.
Cissus is a genus of approximately 350 species of lianas in the grape family (Vitaceae). They have a cosmopolitan distribution, though the majority are to be found in the tropics.
Spartium junceum is the sole species in the genus Spartium. Known as the Spanish broom, rush broom or weaver's broom, it is a species of flowering plant in the family Fabaceae. It is closely related to the other brooms. There are many binomials in Spartium that are of dubious validity.
Menispermaceae is a family of flowering plants. The alkaloid tubocurarine, a neuromuscular blocker and the active ingredient in the 'tube curare' form of the dart poison curare, is derived from the South American liana Chondrodendron tomentosum. Several other South American genera belonging to the family have been used to prepare the 'pot' and calabash' forms of curare. The family contains 68 genera with some 440 species, which are distributed throughout low-lying tropical areas with some species present in temperate and arid regions.
Cocculus is a genus of 11 species of woody vines and shrubs, native to warm temperate to tropical regions of North America, Asia and Africa. The common name moonseed is also used for the closely related genus Menispermum. The related Indian berry is known as "Cocculus Indicus" in pharmacology.
Menispermum canadense, the Canadian moonseed, common moonseed, or yellow parilla, is a flowering plant in the family Menispermaceae, native to eastern North America, from southern Canada south to northern Florida, and from the Atlantic coast west to Manitoba and Texas.

Tephrosia is a genus of flowering plants in the pea family, Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions.
Aspalathus is a genus of flowering plants in the legume family, Fabaceae. The yellow flowers and spiny habit of some species have suggested a resemblance to Ulex europaeus, the thorny "English gorse" Accordingly, "Cape Gorse" has been proposed as a common name although the resemblance is largely superficial; for instance, gorse is thorny, whereas Aspalathus species are variously spiny or unarmed. The genus belongs to the subfamily Faboideae. There are over 270 species, mainly endemic to southwestern fynbos regions in South Africa, with over fifty occurring on the Cape Peninsula alone. The species Aspalathus linearis is commercially important, being farmed as the source of Rooibos tea.
