Rothmannia
Rothmannia is a genus of African flowering plants in the family Rubiaceae. It was described in 1776 and was named after Göran Rothman by Thunberg – both were pupils of Linnaeus.
Description
Although Rubiaceae flowers are generally organized in many-flowered inflorescences, solitary flowers are also found in this genus. The reduction of the number of flowers per inflorescence is often in inverse proportion to the size of the flowers, which explains the large solitary flowers of some Rothmannia.Distribution and species
