Selaginella martensii

Selaginella martensii is a species within the genus Selaginella, commonly known as spike moss. This genus belongs to the family Selaginellaceae and comprises over 700 species of seedless vascular plants distributed globally, particularly in tropical regions. Spike mosses are characterized by their scalelike leaves and spore-bearing structures called strobili. They are heterosporous, meaning they produce two types of spores: megaspores and microspores, which develop into female and male gametophytes, respectively. Selaginella martensii is native to Mexico and is sometimes cultivated as a houseplant.1
