Lycopodium sp.

Clubmosses belong to the division Lycophyta and are small, evergreen plants, with freely branching stems that are covered by rows of scale-like leaves. They are often called ground pines because some species of Lycopodium in the temperate zone grow on the forest floor and bear "cones" that resemble little Christmas trees. Clubmosses superficially resemble the true mosses, but their leaves and stalks are much more rigid. Three species inhabit the Canadian Arctic: alpine clubmoss, Lycopodium alpinum, bristly clubmoss, L. annotinum, and mountain clubmoss, Huperzia selago. The latter species is the only High Arctic resident of the clubmoss family and does not produce cones.

Unbeknownst to most people, clubmosses played a significant role in photography until the invention of battery-operated flash bulbs. Before then, photographers had to use a flash powder to create the flash of light needed to take a photo. This powder contained millions of highly flammable clubmoss spores.
