Almost 2000 new species of plant have been discovered in the past year, according to a report by the UK’s Royal Botanic Gardens at Kew.
Many of the new species have potential as food crops, medicines or sources of timber.
Of the new species there were seven species of the South African plant best known for red bush or rooibos tea discovered. Other discoveries include new relatives of Aloe vera, widely used in the cosmetics and pharmaceutical industries.
Researchers at Kew are also trying to identify which plants are most at risk of extinction. The knowledge is being used to designate protected areas for plants around the world, including several in Africa.
