蕨类的

Here in the rainforest, the giant ohia lehua trees and hapuu ferns provide protective canopy to an amazingly diverse collection of plants and animals.

就在这片雨林中，高大ohia lehua树和那叫hapuu蕨类物给丰富得令人惊奇物撑起了一把保护伞。

Homosporous ferns produce sporophytes by intra gametophytic selfing, inter gametophytic mating, or apogamy.Gametangium ontogeny, genetic load, and ploidy affect the mating system of each species.
