Both Buddleja and Acantholimon are considered which level of classification?
Buddleja Buddleja, or Buddleia (also historically given as "Buddlea"), commonly known as the butterfly bush, is a genus comprising over 140 species of flowering plants endemic to Asia, Africa, and the Americas. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662–1715), an English botanist and rector, at the suggestion of Dr. William Houstoun. Houstoun sent the first plants to become known to science as buddleja ("B. americana") to England from the Caribbean about 15 years after Buddle's death.
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.
