One of the seven plants studied in a recent IUCN report on overexploitation of wild medicinal plants in India is in a genus (Dioscorea) with a number of cultivated species. How many wild medicinal plants worldwide could also be classed as crop wild relatives?
At BGCI we have developed a list of around 3,000 plant species that are used for medicinal purposes. Of these, we know that 1,802 are in cultivation in botanic gardens and this list can be easily extracted from our PlantSearch database (www.bgci.org/plant_search.php) . Simply select ‘medicinal plants’ and the list of medicinal plants that are in cultivation in botanic gardens is displayed. On this list, plants that are also CWR are marked (according to a list of CWR genera). If you download the list, it can be easily be manipulated in excel so you can extract those species (164 species) that are both medicinal plants and crop wild relatives and are in cultivation in botanic gardens.
If anyone is interested, we could provide the full list of plants that are on both our medicinal and CWR lists- not just those in cultivation in botanic gardens.
