Huperzia squarrosa

Other common names for this plant include firmoss or fir clubmoss. Not a true fern or a moss, this plant represents an intermediate stage in evolution from mosses to ferns. Rather than seeds, it reproduces via spores, just as ferns and mosses do.

Scientific classification:
Kingdom:	Plantae
Division:	Lycopodiophyta
Class:	Lycopodiopsida
Order:	Lycopodiales
Family:	Huperziaceae
Genus:	Huperzia
Species:	squarrosa

Natural habitat and growing conditions:

This plant is an ultra-tropical epiphyte (living on tree branches, though not as a parasite) native to tropical rain forests in Southeast Asia. It requires constant warmth, high humidity, bright light and a well-drained moist substrate to perform well.

Notes of interest:

• The spores were used as flash powder for theater effects and cameras in the 19th century, as they burn quickly and brightly but with little heat.
• The plant is structurally similar to the earliest vascular land plants; In the Carboniferous (359-299 million years ago) giant tree-like forms of Lycopodiophyta (the same division of plants as Huperzia, closely related) dominated the landscape; their remains form most of the coal we mine today.
