Tulbaghia is a genus of monocotyledonous herbaceous perennial bulbs native to Africa, belonging to the Amaryllis family.

The genus Heliamphora contains 23 species of pitcher plants endemic to South America. The species are collectively known as sun pitchers, based on the mistaken notion that the heli of Heliamphora is from the Greek helios, meaning "sun". In fact, the name derives from helos, meaning marsh, so a more accurate translation of their scientific name would be marsh pitcher plants. Species in the genus Heliamphora are carnivorous plants that consist of a modified leaf form that is fused into a tubular shape. They have evolved mechanisms to attract, trap, and kill insects; and control the amount of water in the pitcher. At least one species produces its own proteolytic enzymes that allows it to digest its prey without the help of symbiotic bacteria.
Hevea is a genus of flowering plants in the spurge family, Euphorbiaceae, with about ten members. It is also one of many names used commercially for the wood of the most economically important rubber tree, H. brasiliensis.

Brunonia australis, commonly known as the blue pincushion or native cornflower, is a perennial or annual herb that grows widely across Australia. It is found in woodlands, open forest and sand plains. In Cronquist's classification scheme it was the sole member of the monogeneric plant family Brunoniaceae. The APG II system moved it into Goodeniaceae, with which it shares the stylar pollen-cup, or indusium, a character confined to these taxa. Brunonia is unique among Goodeniaceae in its radially symmetric flowers, the superior ovary and the absence of endosperm in the seeds.
Galvezia is a genus of perennial plants which are native to western North America, western South America and the Galapagos Islands. The genus is currently placed in the family Plantaginaceae, having been formerly classified under Scrophulariaceae. It is named in honour of José de Gálvez, a colonial official in New Spain during the 1700s.
Brownea is a genus of about 30 species in the family Fabaceae, subfamily Detarioideae. The genus is native to tropical regions of the Americas. The species are shrubs and trees growing to 20 m tall.
Millettia is a genus of legume in the family Fabaceae. It consists of about 150 species, which are distributed in the tropical and subtropical regions of the world. The genus was formerly known by the name Pongamia, but that name was rejected in favor of the name Millettia, and many species have been reclassified. Due to recent interest in biofuels, Pongamia is often the generic name used when referring to Millettia pinnata, a tree being explored for producing biodiesel.
Brownea coccinea is a species of small native evergreen tree with compound leaves and clusters of bright scarlet flowers in the subfamily Caesalpinioideae of the family Fabaceae.

Julian Alfred Steyermark was an American botanist. His focus was on New World vegetation, and he specialized in the family Rubiaceae.
Brownea grandiceps is a species of tree in the family Fabaceae. Its common names include the rose of Venezuela and the scarlet flame bean. It originated in South America but is now widely grown as a decorative tree in tropical gardens.
Ilex, or holly, is a genus of about 480 species of flowering plants in the family Aquifoliaceae, and the only living genus in that family. The species are evergreen or deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide.
