Lycopodium squarrosum is related to ferns and mosses. It goes by the name rock tassel fern or club moss. This species grows as an epiphyte and is found in Thailand, Madagascar, Australia, China, Indonesia, Micronesia, Taiwan, Fiji and Malaysia.
Huperzia is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses. This genus was originally included in the related genus Lycopodium, from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name firmoss, used for some of the north temperate species, refers to their superficial resemblance to branches of fir (Abies), a conifer. In Australia, the epiphytic species are commonly known as tassel ferns. Lycopodium squarrosum ephiphyte is an Australian native closely related to ancient plants and is probably on a list of those protected. The tassels are stems covered with pale green leaves. As the tassels grow, they cascade making this a wonderful hanging basket choice.
