Spinulum annotinum, synonym Lycopodium annotinum, known as interrupted club-moss,[1] or stiff clubmoss,[2] is a species of clubmoss native to forests of the colder parts of North America (Greenland, St. Pierre & Miquelon, all 10 provinces and all 3 territories of Canada , Alaska, and mountains of the contiguous United States),[3] as well as Asia (China , Russia , Japan , Korea, Nepal, Assam),[4] and most of Europe.[5] The genus Spinulum is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I),[6] but not in other classifications, which submerge the genus in Lycopodium.[7]
Spinulum annotinum is a common and widespread club-moss spreading by means of horizontal stems running along the surface of the ground. It is usually unbranched or sparingly branched, each branch containing a cone at the top. Leaves have minute teeth on their edges.[8][9][10]
