How do plant-lovers perceive ferns?
Species that are known to everyone as edible, such as Bracken and zenmai ; species that are very distinctive in form, such as field horsetail ; species that grow in a unique environment, such as Japanese salamander and Azolla. These species do not seem to be difficult to distinguish.
However, many of the so-called typical ferns are made of pinnate compound leaves, do not flower, and grow quietly in the shade or in the plain habitat. This makes it too difficult to classify and identify them, and it seems to be too much for amateurs to handle.

Later, in response to changes in the Earth's environment, ferns that have grown into smaller and more herbaceous plants.
