Botanical Description

Huperzia selago). Very distinct from the foregoing species in forming erect bushlets 5-15cm tall. Leaves lanceolate to linear, 4-8mm long, semi-erect to spreading, usually deep green, often bearing bud-like gemmae in their axils. Sporangial spikes formed terminally but vegetative extension shoots emerge from their tips. More or less circum-Arctic and in the temperate zone (only on mountains in the south), on heaths, moors, mountain grassland and rock ledges. L.s. subsp. dentata with finely toothed leaves, is restricted to the Azores, while the yellow-green, appressed-leaved subsp. arctica inhabits tundra in Spitzbergen.
