Which genus of plant-life as a larger area of habitation, Centaurea or Commidendrum?
Commidendrum Commidendrum is a genus of trees and shrubs in the sunflower family endemic to the island of Saint Helena in the South Atlantic Ocean. The vernacular name is "gumwood" or "scrubwood".
Acrostichum Acrostichum is a fern genus in the Ceratopteridoideae subfamily of the Pteridaceae. It was one of the original pteridophyte genera delineated by Linnaeus. It was originally drawn very broadly, including all ferns that had sori apparently "acrostichoid", or distributed in a uniform mass across the back of the frond, rather than organized in discrete sori. This led Linnaeus to include such species as "Asplenium platyneuron" in the genus, because the specimen he received had sori so crowded that it appeared acrostichoid.
