ian botanist.
Kuhlmann was a specialist on Taxonomy
of Angiosperms. He was a great collector of herborized
material (his collection was gathered at a museum - Botanical Museum Kuhlmann, created in 1960, later the Botanical Museum of the Botanical Garden of Rio de Janeiro opened to the public on September 20, 1991, incorporated this collection of the Kuhlmann Museum ) and notable connoisseur of the Brazilian Flora, influencing a large number of researchers in this area of the knowledge in Brazil, for example William Rodrigues. He published about eighty works, describing new genera (see below), and species. He also erected two families. He put Peridiscus in a family by itself in 1950. Peridiscaceae
has since been expanded to include Medusandra,Soyauxia
, and Whittonia. He also put Duckeodendron into its own family, Duckeodendraceae, but this, and other segregates
of Solanaceae
are no longer recognized as separate families by APG.
In 1944 he became the director of the Rio de Janeiro Botanical Garden
, exerting this function up to 1951.
J. G. Kuhlmann created the Botanical Society of Brazil .
The genera Kuhlmannia J.C.Gomes, synonym of Pleonotoma, Bignoniaceae
and Kuhlmaniella Barroso, synonym of Dicranostyles, Convolvulaceae
are named in his honour.
