5-476: 19; see text Parakohleria Wiehler (1978) Pearcea is a genus of tropical herbaceous plants in the family Gesneriaceae native to western South America. It is classified in tribe Gloxinieae and is closely related to the genus Kohleria , in which some of its species were previously included. The genus Parakohleria has recently been synonymized under Pearcea , a conclusion later supported by molecular analyses that showed that Pearcea hypocyrtiflora
10-793: The University of Miami . 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 . 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
15-568: The tests of recent molecular phylogenies . 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 . 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 . He has named
20-583: Was a German botanist who specialized in the plant family Gesneriaceae . 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
25-480: Was nested within the former Parakohlerias. The best-known and most widely cultivated species is Pearcea hypocyrtiflora , a low-growing herb with attractively marked leaves and unusual bubble-like red or orange flowers. 19 species are accepted.
