Subfamily Huperzioideae

The Huperzioideae, known as firmosses, have also been treated as a separate family Huperziaceae. Firmosses differ from other Lycopodiaceae in that they grow in clumps, instead of producing creeping, horizontal stems like other family members.[1] Of the three genera in this group, Huperzia is a temperate and actic genus and is the only one found naturally in New York. Of the other two genera, Phlegmariurus is native to tropical and subtropical regions, and Phylloglossum is native to Australia and New Zealand.

Huperzia
Huperzia lucidula, shining firmoss
Commonly known as firmoss or fir-clubmoss, Huperzia (hoo-per-zee-uh) was named for Johann Peter Huperz, an early 19th century German botanist who specialized in ferns.

        Dendrolycopodium
        Tree clubmoss
        From Greek δενδρος (denros: tree), λυκος (lukos: wolf), and ποδιων (podion: legs), Dendrolycopodium (den-drō-lī-kə-ˈpō-dē-əm) contains tree-clubmoss species, which are fairly erect and have branched stems. This genus, also treated as Lycopodium sect. Obscura, is characterized by stalked terminal strobili, which contain their sporangia.

                    1. ↑ The New York Flora Atlas and New England Wild Flower Society list the spiny-spore quillwort as Isoëtes echinospora ssp. muricata because the leaves of the North American plants of bear stomata, while those of the European plants do not. The other sources used here treat ssp. muricata as a synonym.
