rock selaginella

The rock selaginella, or Selaginella rupestris, is a species of spike moss, a type of seedless vascular plant belonging to the family Selaginellaceae. These plants are found worldwide, especially in tropical regions, and often grow in forests or dry areas.1

Rock selaginella is characterized by its small leaves and stems that grow on rocks or in sand. Like other spike mosses, it is heterosporous, meaning it produces two types of spores: larger megaspores that develop into female gametophytes and smaller microspores that develop into male gametophytes. This reproductive characteristic is a key feature of the genus Selaginella.123
