He named the small genus Synanthes (P.Burns-Balogh, H.Rob. & Mercedes S.Foster) of epiphytic orchids from Paraguay.
The tribe Eupatorieae is known for the many secondary metabolite chemicals such as alkaloids, (poly)acetylenes, and terpenoids (see Ichthyothere). Robinson has made a detailed study of these chemicals, together with R.M. King and Ferdinand Bohlmann.
