Friedrich Ritter

Friedrich Ritter was a German botanist and geologist. He mainly studied spermatophytes, particularly cacti.

At some point, Ritter had graduated from the University of Marburg. After graduating, Ritter moved to live with his parents in Mexico in 1920. While in Mexico, he began to become interested in studying cacti. From 1930, he went to Argentina, Bolivia, Chile, and Peru, discovering and collecting new species.

Several plants have been named after Ritter. These include the cactus genus, Ritterocereus, along with several other species, including Aztekium ritteri, Espostoa ritteri, Lobivia ritteri, and Parodia ritteri.

When citing a botanical name, Friedrich Ritter is abbreviated as F.Ritter
