This diminutive species is found at higher elevations where it is cooler, and misty clouds and rain is an everyday occurrence. In these conditions you can see them in colonies with their long serrated leaves shooting out from the moss. When C. serrulatum grows in more open areas, they tend to stay small and hug the tree a little more. It is common and abundant if the conditions are right. Growing alongside other ferns and mosses is when it looks it’s best.
