Is Pteris Pteris a national first-class protected plant?
Pteris Pteris is a national first-class protected plant.

Pteris spinulosa, also known as Alsophila spinulosa, is a precious plant under state protection. According to human inference, Dryopteris hominis has existed for at least 300 million years, or earlier 1 100 million years. It is a veritable aborigine and occupies an important position in scientific research. Secondly, the value of Pteris Pteris is that it has a long history and is the only woody fern left here. Its shape is similar to trunk and hollow trunk, which is very ornamental. Finally, the growth conditions of Pteris Pteris are very bad and it is difficult to raise Pteris Pteris artificially. Because it has not fully adapted to the land environment, its breeding mode mainly depends on water flow. The requirements for its growing environment are: warm in winter and hot in summer, and high air humidity.
