In between Tagetes and Tetradium which one was described as a genus by Linnaeus in 1753?
Tagetes Tagetes is a genus of annual or perennial, mostly herbaceous plants in the sunflower family (Asteraceae or Compositae). It was described as a genus by Linnaeus in 1753.
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.
