What has more species: Gesneria or Bosea?
Gesneria Gesneria is a genus of approximately 50 species in the flowering plant family Gesneriaceae. Except for two or three odd South American species, all are native to islands of the Caribbean. The genus is classified in the tribe Gesnerieae along with the genera "Bellonia", "Pheidonocarpa", and "Rhytidophyllum". "Gesneria" species are usually woody shrubs or subshrubs, and (with the closely related "Rhytidophyllum") are unusual in the family in having alternately (rather than decussately) arranged leaves. A complete list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
Forstera Forstera is a genus of small perennial plants in the Stylidiaceae family named in honour of the German naturalists Johann Reinhold Forster and his son, Georg Forster, who had previously described "Forstera"'s sister genus, "Phyllachne" just five years earlier. It comprises five species that are endemic to New Zealand with the exception of "F. bellidifolia", which is endemic to Tasmania. The species in this genus resemble those in a subgenus of the related genus "Stylidium" called "Forsteropsis", but they are more closely related to the genus "Phyllachne". Proposals to merge the two genera based on information from cladistic analysis have emerged because of these genera's morphological similarities and evidence that they are paraphyletic.
