Over 1,700 new species of plants have been discovered in the past year, with many having potential as food crops, medicines or sources of timber, according to a new report.
Other discoveries include new relatives of Aloe Vera, widely used in the cosmetics and pharmaceutical industries.
The new discoveries hold "huge promise" for the future, said Professor Kathy Willis, director of science at the Royal Botanic Gardens.
"It is really important to find these new species because they may well hold the genetic code — or the key — to more resilient food crops from pests and pathogens and climate change into the future," Willis said.
The report also revealed that a growing number of plants have had their genomes sequenced to find out more about their biology.
