What type of vegetation does Ceratostigma and Crocosmia have in common?
Crocosmia Crocosmia ( ; J. E. Planchon, 1851) (montbretia) is a small genus of flowering plants in the iris family, Iridaceae. It is native to the grasslands of southern and eastern Africa, ranging from South Africa to Sudan. One species is endemic to Madagascar.
Ceratopteris richardii Ceratopteris richardii is a fern species belonging to the genus Ceratopteris, one of only two genera of the "Ceratopteridoideae" subfamily of the Pteridaceae. It is one of several genera of ferns adapted to an aquatic existence. "C. richardii" was previously regarded as being part of the species "Ceratopteris thalictroides". This particular species is of special scientific interest because a patented strain has been developed as a scientific aid and teaching tool in biology, called "C-fern."
