Psyllocarpus is a genus of flowering plants belonging to the family Rubiaceae. [1] It is an endemic genus of Brazil found in Amazonia, Caatinga, and Cerrado. [2] In 1979 the genus was revised by Kirkbride into two sections, Psyllocarpus sect. Psyllocarpus and P. sect Amazonica, based on geographic distribution and morphology. Plants of the World Online treats the genus as a synonym of Tapanhuacanga . [1]
Psyllocarpus sect. Psyllocarpus comprises P. asparagoides, P. bahiensis, P. goiasensis, P. laricoides, P. phyllocephalus, P. scatignae, P. schwackei. Psyllocarpus sect. Amazonica includes P. campinorum, P. cururuensis, P. psyllocarpoides.
Psyllocarpus intermedius and Psyllocarpus densifolius are found in the same geographical region at sect. Psyllocarpus but are morphologically distinct. Carmo et al. (2021) recognized the monotypic genus Diadorimia to accommodate P. densifolius, while the determination of P. intermedius is pending further investigation. [2]
Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas. It can also be found in South Africa. The generic name is also used as the common name.
Sterculia is a genus of flowering plants in the mallow family, Malvaceae: subfamily Sterculioideae. Members of the genus are colloquially known as tropical chestnuts. Sterculia may be monoecious or dioecious, and its flowers unisexual or bisexual.
Coccocypselum is a genus of flowering plants in the family Rubiaceae. It is native to Mexico, Central America, the West Indies and South America. All species of the genus Coccocypselum are herbaceous with fleshy, blue or purple fruits, and 4-petaled flowers.
Bonnetia is a genus of flowering plants in the family Bonnetiaceae. Most of the roughly 30 species are shrubs. The remaining species, all trees, are among the dominant species in the forest vegetation on the tepui plateaus of northern South America, such as B. roraimae on the summit of Mount Roraima.
Bikkia is a genus of flowering plants in the family Rubiaceae. It is native to the Philippines, the Maluku region of eastern Indonesia, New Guinea and the western Pacific. The genus was named by Caspar Reinwardt in 1825. Seven of the New Caledonian species previously included in Bikkia were transferred to a separate genus, Thiollierea, in 2011 based on molecular and morphological information.
Canthium is a genus of flowering plants in the family Rubiaceae. They are shrubs and small trees. The leaves are deciduous and the stems are usually thorny.
Simira is a genus of plants in the family Rubiaceae. It contains the following species:
Philcoxia is a genus of seven rare plant species in the Plantaginaceae that are endemic to Brazil and resemble terrestrial species of the genus Utricularia. The genus, formally described in 2000, consists of the species P. bahiensis, P. goiasensis, P. minensis, P. tuberosa, P. rhizomatosa, P. maranhensis and P. courensis, each of the first three named for the Brazilian state to which it is endemic. The species are characterized by subterranean stems, peltate leaves at or below the soil surface, and five-lobed calyces. Their habitat has been reported as areas of white sand in the midst of cerrado vegetation at an elevation between 800 and 1450 m. Initial descriptions of the genus included suspicions that the plethora of stalked capitate glands on the upper surfaces of leaves was an indication that these species may be carnivorous. A study published in 2007 tested P. minensis for protease activity, a typical test for the carnivorous syndrome, and could detect none. Later studies detected other digestive enzymes such as phosphatases and qualitatively assessed prey digestion and nutrient uptake, suggesting that it is a true carnivorous plant. The genus epithet honors David Philcox (1926-2003), a botanist at Kew Gardens who worked extensively in tropical Scrophulariaceae.
Portlandia is a genus of flowering plants in the coffee family, Rubiaceae. Members of the genus are endemic to Jamaica.

Canthium armatum is a species of flowering plants in the family Rubiaceae. It is a shrub or tree native to southern Mozambique, Eswatini, and KwaZulu-Natal and the Northern Provinces of northeastern South Africa. The species is characterized by the presence of large spines.
Arcytophyllum is a genus of flowering plants in the family Rubiaceae. The genus contains 18 species, distributed from New Mexico to Bolivia.
Coussarea is a genus of flowering plants in the family Rubiaceae. The genus is found from southern Mexico to tropical America.
Declieuxia is a genus of flowering plants in the family Rubiaceae. The genus is found in tropical America.
Spermacoceae is a tribe of flowering plants in the family Rubiaceae and contains about 1346 species in 57 genera. Its representatives are found in the tropics and subtropics.
Coffeeae is a tribe of flowering plants in the family Rubiaceae and contains about 333 species in 11 genera. Its representatives are found in tropical and southern Africa, Madagascar, the western Indian Ocean, tropical and subtropical Asia, and Queensland.
Staelia is a genus of flowering plants belonging to the family Rubiaceae.
Paganuccia is a monotypic genus of flowering plants in the Rubiaceae family. The genus contains only one species, viz. Paganuccia icatuensis, which is endemic to the continental dunes in the São Francisco River basin, Bahia, north-eastern Brazil. Morphological and molecular phylogenetic analyses support the recognition of this new genus within the Spermacoce clade of the tribe Spermacoceae.
Tapanhuacanga is a genus of flowering plants in the family Rubiaceae. It includes 11 species endemic to Brazil.
