There are two main categories of cryophytes:
* Psychrophytes: These plants are adapted to cold but not freezing temperatures. They often live in high altitude or high latitude regions.
* Cryophytes proper: These plants are specifically adapted to survive freezing temperatures. They can be found in arctic and alpine regions, and some even live in permafrost.
Other terms you might come across include:
* 寒帯植物 (Kantō Shokubutsu): This is the Japanese term for cold-climate plants.
* Cold-hardy plants: This is a more general term that refers to plants that can tolerate cold temperatures, but it doesn't necessarily imply they are specifically adapted to cold environments.
