What type of vegetation does Ceratostigma and Crocosmia have in common?
Ceratostigma Ceratostigma ( ; ), or leadwort, plumbago, is a genus of eight species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of Africa and Asia. Common names are shared with the genus "Plumbago".
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."
