Hans Joachim Wiehler (1930-2003) was a Prussian-born American botanist who specialized in the plant family Gesneriaceae. Gesneriaceae is a family of Flowering plants consisting of ca In 1954 he received a Bachelor of Arts degree from Goshen College in Goshen, Indiana and a Bachelor of Divinity degree from Goshen Biblical Seminary in 1956. He married in 1958 and remained in the United States for the rest of his life. He obtained a Master's degree in Botany from Cornell University and in 1979 a PhD in Botany from the University of Miami. The University of Miami (also known as Miami of Florida, UM, or just The U) is a private non-sectarian University founded in 1925 Wiehler was on the staff of the Marie Selby Botanical Gardens from 1973 until 1982, when he left Selby to found the Gesneriad Research Foundation in Sarasota, Florida. The Marie Selby Botanical Gardens (7 acres 28 hectares are extensive Botanical gardens dedicated to research and collections of Epiphytes especially Orchids
Wiehler tended to be a taxonomic "splitter" but many of his generic rearrangements have found acceptance: the segregation of Gasteranthus from Besleria, of Alsobia, Chrysothemis, Nautilocalyx, and Paradrymonia from Episcia, and of Moussonia from Kohleria, have all withstood the tests of recent molecular phylogenies. Gasteranthus is a Genus of 35 species of Herbs and soft-stemmed Subshrubs in the Flowering plant family Gesneriaceae Besleria is a Genus of ca 150 species of large Herbs and soft-stemmed Subshrubs or Shrubs in the Flowering plant family Alsobia is a Genus of Flowering plants in the family Gesneriaceae, native to Mexico Guatemala and Costa Rica In Botany, Chrysothemis is a genus in the family Gesneriaceae. UserPolbot. --> Nautilocalyx is a genus of Plant in family Gesneriaceae. UserPolbot. --> Paradrymonia is a genus of Plant in family Gesneriaceae. Episcia is a genus of about 8 species belonging to the Flowering plant family Gesneriaceae. Kohleria is a New World Genus of the Flowering plant family Gesneriaceae. However, most gesneriad specialists have not accepted his segregation of Bucinellina, Dalbergaria, Pentadenia, and Trichantha from Columnea, and his new genus Parakohleria has been synonymized under Pearcea. Columnea is a genus of ca 200 species of epiphytic herbs and Shrubs in the Flowering plant family Gesneriaceae, native to tropical Columnea is a genus of ca 200 species of epiphytic herbs and Shrubs in the Flowering plant family Gesneriaceae, native to tropical Columnea is a genus of ca 200 species of epiphytic herbs and Shrubs in the Flowering plant family Gesneriaceae, native to tropical Columnea is a genus of ca 200 species of epiphytic herbs and Shrubs in the Flowering plant family Gesneriaceae, native to tropical Pearcea is a South American Genus of 17 species of Tropical Herbs in the Flowering plant Family Gesneriaceae His rare instances of taxonomic "lumping" have not been as widely accepted; Gloxinia sensu Wiehler is a polyphyletic assemblage, recently dismembered, and no other botanists have accepted his synonymy of Rhytidophyllum and Pheidonocarpa under Gesneria. In Phylogenetics, a Taxon is polyphyletic ( Greek for "of many races" if the trait its members have in common evolved separately in different Gesneria is a Genus of approximately 50 species in the Flowering plant family Gesneriaceae.
His standard botanical abbreviation is : Wiehler
He has named the nothogenus ×Koellikohleria Wiehler (family Gesneriaceae) in Baileya, 16: 30 (1968). Taxonomic rank ( rank, category, taxonomic category is an abstract term used in the Scientific classification, or Taxonomy, of organisms
