Zanthoxylum is a genus of about 250 species of deciduous and evergreen trees, shrubs and climbers in the family Rutaceae that are native to warm temperate and subtropical areas worldwide. It is the type genus of the tribe Zanthoxyleae in the subfamily Rutoideae. Several of the species have yellow heartwood, to which their generic name alludes.
Vachellia anegadensis, the pokemeboy, is a species of plant in the family Fabaceae. It is found only in the British Virgin Islands. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical dry shrubland, sandy shores, and rural gardens. It is threatened by habitat loss.
The spotted quail-thrush is a species of bird in the family Psophodidae. It is endemic to Australia.

It is threatened by habitat loss. Like other Hawaiian Melicope, this species is known as alani. This is a federally listed endangered species of the United States.
Zanthoxylum atchoum is a forest tree in the family Rutaceae that grows in Côte d'Ivoire's Eastern Guinean forests. It is endemic to Côte d'Ivoire where it is threatened by habitat loss. Waterman assigned Z. atchoum to this combination after morphological and secondary metabolite evidence revealed that Fagara should be subsumed in Zanthoxylum.
Zanthoxylum chevalieri is a species of plant in the family Rutaceae. It is endemic to Ghana. It is threatened by habitat loss.
Zanthoxylum flavum is a medium-sized tree in the family Rutaceae. Common names include noyer, West Indian satinwood, yellow sanders, tembetaria, and yellow sandalwood. It is native to Anguilla, Antigua and Barbuda, the Bahamas, Bermuda, Cuba, the Dominican Republic, Guadeloupe, Haiti, Jamaica, Puerto Rico, and the Florida Keys, exclusive of Key West where it has been extirpated. It is threatened by habitat loss and harvesting for its dense, durable wood used in fine woodworking.
Zanthoxylum harrisii is a species of plant in the family Rutaceae. It is endemic to Jamaica. It is threatened by habitat loss.
Zanthoxylum hawaiiense, commonly known aʻe or Hawaiʻi pricklyash, is a species of flowering plant in the family Rutaceae, that is endemic to Hawaii. It can be found at elevations of 550–1,740 m (1,800–5,710 ft) in dry forests, where it grows on lava flows, and mixed mesic forests on the Island of Hawaiʻi, Maui, Molokaʻi, and Lānaʻi. It is threatened by habitat loss.
Zanthoxylum heterophyllum is a species of plant in the family Rutaceae. It is found in Mauritius and Réunion. It is threatened by habitat loss. Formerly this species also occurred in Rodrigues, where it had been eradicated. In Mauritius less than 40 individuals are known in the wild.
Zanthoxylum kauaense, commonly known as aʻe or Kauaʻi pricklyash, is a species of flowering plant in the family Rutaceae, that is endemic to Hawaii. It usually inhabits mixed mesic forests at elevations of 300–1,980 m (980–6,500 ft), but can also be found in dry and wet forests. It is threatened by habitat loss.
Zanthoxylum oahuense, commonly known as aʻe or Oʻahu prickly-ash, is a species of flowering plant in the family Rutaceae, that is endemic to the island of Oʻahu in Hawaii. It is a small tree, reaching a height of 5 m (16 ft). Aʻe inhabits mixed mesic and wet forests at elevations of 580–800 m (1,900–2,620 ft). It is threatened by habitat loss.
Zanthoxylum americanum, the common prickly-ash, common pricklyash, common prickly ash or northern prickly-ash, is an aromatic shrub or small tree native to central and eastern portions of the United States and Canada. It is the northernmost New World species in the citrus family, Rutaceae, and is the type species in its genus, which includes sichuan pepper. It can grow to 10 meters (33 ft) tall with a diameter at breast height (DBH) of 15 cm (5.9 in). It produces membranous leaflets and axillary flower clusters. The wood is not commercially valuable, but oil extracts from the bark have been used in traditional and alternative medicine, and have been studied for antifungal and cytotoxic properties. The genus name is sometimes spelled Xanthoxylum.
Zanthoxylum dipetalum is a rare species of tree in the family Rutaceae and in the same genus as Szechuan pepper. It is known by the Hawaiian names Kāwa'u and Heaʻe and is endemic to the Hawaiian archipelago, where it grows in forests on 3 or 4 of the islands.

This seagrass is widespread through the Gulf of Aqaba. Recently it has arrived in the Caribbean where it is also spreading.
Tropical Important Plant Areas (TIPAs) is a programme established by the Royal Botanic Gardens, Kew in 2015 in collaboration with Plantlife International, to provide a framework to identify sites important for preserving plant diversity in tropical countries. The programme is based on the Important Plant Areas (IPAs) framework set up by Plantlife International. The IPA criteria were modified to take into account the high plant richness, the limited availability of data and the higher dependence on socio-economically important yet native plants for livelihoods in the tropics. The framework acknowledges the practical problems of gathering plant and habitat data in many regions of the world, and it recognises the important role of peer reviewed expert opinion in the selection process. TIPAs can be identified based on a range of organism groups within the plant and fungal kingdoms, including algae, fungi, lichens, liverworts, mosses, and wild vascular plants. The TIPAs programme focuses on critical sites for wild plant populations. It aims to identify areas important for the conservation of threatened plants and/or habitats and areas with exceptional plant richness, and to raise awareness of the importance of plant life in tropical countries, encouraging long term conservation of these areas. TIPA sites are selected based on three criteria:
