Research
Together with collaborators, he investigated the taxonomy of several bryophytes, green algae (co-naming a new genus Struveopsis), vines of family Hippocrateaceae (nom. cons.) (now a synonym of the staff vine family Celastraceae).
He made a study of the phylogeny of the genus Houstonia, madder family (Rubiaceae).
In 1974 he named a new subtribe Luziolinae of oryzoid (= rice-like) grasses Poaceae, but this was not supported by a recent molecular study (Duvall et al., 1993).
He named the small genus Synanthes (P.Burns-Balogh, H.Rob. & Mercedes S.Foster) of epiphytic orchids from Paraguay.
He also named 32 new species from the bromeliad family (Bromeliaceae), mostly in the genera Navia and Lindmania, Connellia, and Cottendorfia, such as Navia albiflora L.B.Smith, Steyermark & Robinson and Navia aliciae L.B.Smith, Steyermark & Robinson. In 1999 he merged Pepinia into Pitcairnia at generic level. (Harvard Papers in Botany Vol. 4 no.1 195 – 202). He made several illustrations for the Catalog of Botanical Illustrations, Smithsonian Institution, such as for Brewcaria duidensis (Bromeliaceae).
But his major interest went to the sunflower family (Asteraceae). In the neotropical tribe Eupatorieae (Asteraceae), Robinson (with co-worker King) has named at least one species in 27 of the genera. He later worked on the reorganization of the tribes Senecioneae, Heliantheae, Liabeae and lately Vernonieae.
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. This resulted in a large number of publications mostly in the journal Phytochemistry in the 1970s and 1980s.
In 1970 Robinson and King stressed the need for diagnostic character analysis in his classic article entitled The new synantherology (Taxon 19: 6-11).
In 1986 he gave a critical but constructive opinion on cladistics in the article. ”A key to the common errors of cladistics”. (Taxon 35: 309-311).
The genus Robinsonecio T.M.Barkley & J.P.Janovec (Asteraceae) is named for him.

Famous quotes containing the word research:
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
“... research is never completed ... Around the corner lurks another possibility of interview, another book to read, a courthouse to explore, a document to verify.”
—Catherine Drinker Bowen (1897–1973)
“I did my research and decided I just had to live it.”
—Karina O’Malley, U.S. sociologist and educator. As quoted in the Chronicle of Higher Education, p. A5 (September 16, 1992)
