The Lycopodiales ...

Family Lycopodiaceae[edit]

The Lycopodiaceae (clubmoss family).[1]
  1. Lycopodiaceae Troy Weldy & David Werier (2013) New York Flora Atlas. New York Flora Association, Albany, New York.

Subfamily Huperzioideae[edit]

Shining firmoss.
The Huperzioideae, known as firmosses, have also been treated as a separate family Huperziaceae. They differ from other Lycopodiaceae in that they grow in clumps, instead of producing creeping, horizontal stems like other family members.[1]

The only genus of this group found naturally in New York is Huperzia.


Genus Huperzia[edit]
Commonly known as firmoss or fir-clubmoss, Huperzia was named for Johann Peter Huperz, an early 19th century German botanist who specialized in ferns.

From Greek δενδρος (denros: tree), λυκος (lukos: wolf), and ποδιων (podion: legs), Dendrolycopodium 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.
