Goodyer added many plants to the British flora. He is credited with clarifying the identities of the British elms, and for discovering an unusual elm endemic to the Hampshire coast between Lymington and Christchurch named for him as Goodyer's elm; this was believed by the botanist Ronald Melville to be a form of the Cornish elm. He is also believed to have introduced the Jerusalem artichoke to English cuisine. Although not formally trained in medicine, like many herbalists of his time, he had a small practice using herbal remedies, skills he passed on to his nephew, Rev. Edmund Yalden.
