Hagenia is a monotypic genus of flowering plant with the sole species Hagenia abyssinica, native to the high-elevation Afromontane regions of central and eastern Africa. It also has a disjunct distribution in the high mountains of East Africa from Sudan and Ethiopia in the north, through Kenya, Uganda, Rwanda, Burundi, Democratic Republic of Congo, and Tanzania, to Malawi and Zambia in the south. A member of the rose family, its closest relative is the Afromontane genus Leucosidea.

Goldenseal (Hydrastis canadensis), also called orangeroot or yellow puccoon, is a perennial herb in the buttercup family Ranunculaceae, native to North America. It may be distinguished by its thick, yellow knotted rootstock. The stem is purplish and hairy above ground and yellow below ground where it connects to the yellow rhizome. Goldenseal reproduces both clonally through the rhizome and sexually, with clonal division more frequent than asexual reproduction. It takes between 4 and 5 years for a plant to reach sexual maturity, i.e. the point at which it produces flowers. Plants in the first

Gamboge ( ) is a deep-yellow pigment derived from a species of tree that primarily grows in Cambodia. Popular in East Asian watercolor works, it has been used across a number of media dating back to the 8th century. Easy to transport and manipulate into a durable watercolor paint, gamboge is notable for its versatility as a pigment in how it has been used in paintings, printing of books, and garment dyes, including the robes of Buddhist monks. Gamboge is toxic to humans, and is potentially deadly in large doses. Due to its toxicity and poor lightfastness, gamboge is no longer used in paints, t

Cochlospermum is a genus of trees in the Bixaceae family; some classifications place this genus in the family Cochlospermaceae. It is native to tropical regions of the world, particularly Latin America, Africa, the Indian subcontinent, and Australia.

Acridocarpus (from Gr. Akris, a locust and carpos, a fruit, alluding to the winged fruit) is a genus of flowering plants in the family Malpighiaceae. Species in this genus are native to Arabia and tropical and subtropical Africa, with one species in New Caledonia.

Baphia is a small genus of legumes that bear simple leaves. Baphia is from the Greek word βάπτω (báptō-, "to dip" or "to dye"), referring to a red dye that is extracted from the heartwood of tropical species. The genus is restricted to the African tropics. Baphia was traditionally assigned to the tribe Sophoreae; however, recent molecular phylogenetic analyses reassigned Baphia to the tribe Baphieae.

Aurantinidin is a water-soluble, red plant dye. It is a member of the class of compounds known as anthocyanidins and is a hydroxy derivative of pelargonidin. Aurantinidin has been reported to occur in Impatiens aurantiaca (Balsaminaceae), and also in cultivars from genus Alstroemeria.

Lawsone (2-hydroxy-1,4-naphthoquinone), also known as hennotannic acid, is a red-orange dye present in the leaves of the henna plant (Lawsonia inermis), for which it is named, as well as in the common walnut (Juglans regia) and water hyacinth (Pontederia crassipes). Humans have used henna extracts containing lawsone as hair and skin dyes for more than 5,000 years. Lawsone reacts chemically with the protein keratin in skin and hair via a Michael addition reaction, resulting in a strong permanent stain that lasts until the skin or hair is shed. Darker colored staining is due to more lawsone–kera

Brazilin is a naturally occurring, homoisoflavonoid, red dye obtained from the wood of Paubrasilia echinata, Biancaea sappan, Caesalpinia violacea, and Haematoxylum brasiletto (also known as Natural Red 24 and CI 75280). Brazilin has been used since at least the Middle Ages to dye fabric, and has been used to make paints and inks as well. The specific color produced by the pigment depends on its manner of preparation: in an acidic solution brazilin will appear yellow, but in an alkaline preparation it will appear red. Brazilin is closely related to the blue-black dye precursor hematoxylin, hav

Cynomorium is a genus of parasitic perennial flowering plants in the family Cynomoriaceae. The genus consists of only one species, Cynomorium coccineum (although one of its subspecies is sometimes treated as a separate species). Its placement in the Saxifragales was resolved in 2016 with the help of nuclear, plastid, and mitochondrial sequences obtained from next-generation sequencing. Common names include the misleading Maltese fungus or Maltese mushroom; also desert thumb, red thumb, tarthuth (Bedouin) and suoyang (Chinese). A rare or local species, it grows in dry, rocky or sandy soils, oft

Desfontainia is a genus of flowering plants in the family Columelliaceae, though it was placed formerly in Loganiaceae, Potaliaceae (later subsumed in Gentianaceae), or a family of its own, Desfontainiaceae.
