Käthe Hoffmann
Johanna Emilie Katharina Elizabeth "Käthe" Hoffmann (1 August 1883 – 30 December 1960) was a German botanist who described many plant species in New Guinea and South East Asia including Annesijoa novoguineensis. She was a high school teacher at Breslau, German Empire, (now Wrocław, Poland) and made a significant contribution to botany. In one study, she was found to have co-authored or authored 354 land plant species, the sixth-highest number authored by any female scientist. As of May 2020, Plants of the World Online lists 439 accepted genera and species which include Käthe Hoffmann in the authority, in some capacity.
