Interrupted Clubmoss in Detail.

Interrupted clubmoss (Lycopodium annotinum) can be found in Alaska, particularly in the southeastern and southcentral coastal parts of the state, where it grows in wetlands, bogs, and other moist habitats. It is also found in other regions of Alaska, such as the Aleutian Islands, the Alaska Peninsula, and the Kodiak Archipelago.

Interrupted clubmoss is a perennial plant that grows up to 1ft (30 cm) in height. It has a creeping stem that can spread up to 6.5ft (2 m) in length, and small, needle-like leaves that are arranged in whorls around the stem. The plant produces spores in cone-like structures at the tips of some branches.

In traditional medicine, Lycopodium annotinum has been used to treat a variety of conditions such as respiratory ailments, digestive issues, kidney problems, and urinary tract infections. It has also been used as a diuretic, astringent, and to treat skin conditions.

In addition, Lycopodium annotinum has cultural significance for Alaska Natives. In some communities, the plant is used in traditional ceremonies and as a component of regalia. The plant's unique appearance, with its needle-like leaves arranged in whorls around the stem, also makes it a popular ornamental plant in Alaska gardens.

However, as with all plants, it is important to be aware of the potential risks associated with using Lycopodium annotinum for medicinal or other purposes. The plant contains toxic alkaloids that can be harmful if ingested in large amounts, and it should only be used under the guidance of a qualified healthcare professional or traditional healer.

Lycopodium annotinum has also been used in the manufacturing of fireworks and as a source of fuel for fires.
