Kohleria is a New World genus of the flowering plant family Gesneriaceae. The plants are generally tropical herbs or subshrubs with velvety stems and foliage and brightly colored flowers with spots or markings in contrasting colors. They are rhizomatous and commonly include a period of dormancy in their growth cycle. The genus was recently revised by Kvist & Skog (1992) and was recognized as having 19 species distributed in Central America and South America. Recent phylogenetic work by Roalson et al. (2005) indicated that the epiphytic genus Capanea is derived from within Kohleria, and the two species of Capanea were subsequently transferred to Kohleria. The genus Pearcea is closely related.
Because of their colorful and exotically patterned flowers, as well as a general interest in the many tropical flowering plants that were being introduced for the first time from the Americas, kohlerias were very popular in England and Europe in the 19th Century. Many species and hybrids were lavishly illustrated in horticultural magazines such as Curtis's Botanical Magazine under the discarded or erroneous names of Achimenes, Gesneria, Isoloma, Sciadocalyx, and Tydaea. These species and hybrids almost entirely disappeared in the early 20th Century, and plant breeders have only recently begun to work extensively with this genus again.
Several species are widespread, variable, weedy, and tend to hybridize in the wild, and numerous names have been described that are synonyms of other species or are hybrid taxa.
