how is Brassia and Comesperma connected?
Comesperma Comesperma is a genus of shrubs, herbs and lianas in the family Polygalaceae. The genus is endemic to Australia. It was defined by the French botanist Jacques Labillardière in his 1806 work "Novae Hollandiae Plantarum Specimen". The genus name is derived from the Ancient Greek words "come" ("hair") and "sperma" ("seed"), and relates to the seeds bearing tufts of hair. The genus is distributed over southern Australia, particularly in the southwest of Western Australia, where 19 species are found. 24 species have been described.
Gustavia (plant) Gustavia is a genus of flowering plants of Lecythidaceae family described by Linnaeus in 1775. It is native to tropical Central America and South America. Many of the species are threatened; some are critically endangered "Gustavia superba", though, is actually abundant in re-growing secondary forests. It grows in northern South America, from Panama south through the Andes as far as Ecuador, and along the Caribbean coast and in the Amazon basin.
