I only know the common name of a plant, how can I use ePIC?
ePIC only handles searches by scientific name. We do not have a database at Kew that allows you to look up the scientific name for any given common name, and there is no comprehensive database that we are aware of, but we do have a list of URLs which might help. See the IPNI FAQ – question 8 In general, you have to beware that common names can mean different things to different people, will vary from country to country (sometimes between regions), and often will not indisputably link to a single species.
