What plant genus has more species, Dichroa or Cyananthus?
Dichroa Dichroa is a genus of 12 species of flowering plants in the family Hydrangeaceae, native to eastern and southeastern Asia. They are deciduous shrubs growing to 1-3 m tall, with their leaves arranged in opposite pairs. The flowers are produced in a broad inflorescence similar to that of the related genus "Hydrangea". The fruit is a glossy metallic purple-blue berry.
Diplarrena Diplarrena is a genus of flowering plants in the iris family, Iridaceae. The two species are endemic to Australia. The name is from Greek "diploos" ("double") and "arren" ("male"); plants in the genus have only two functional stamens, while all other Iridaceae have three. The name is often misspelled "Diplarrhena", an error that began with George Bentham's "Flora Australiensis" in 1873.
