## Appearance

The stag's-horn clubmoss is a low-growing plant with creeping stems that send up erect, branched stems covered in tiny, scale-like, bright green leaves. Its yellow-brown, club-shaped spore cones resemble miniature antlers, making it visually distinct from true mosses.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Lycopodiopsida
- **Order:** Lycopodiales
- **Family:** Lycopodiaceae
- **Genus:** Lycopodium

## Interesting facts

- Despite its name, it's not a true moss; it's an ancient plant related to ferns!
- Its powdery spores are so flammable, they were once used in fireworks and flash photos!
- This plant is a living fossil, growing on Earth when dinosaurs roamed!
- Unlike flowering plants, it reproduces with tiny spores, not seeds, like ancient ferns!

## Special abilities

- **Spore Power:** The stag's-horn clubmoss has tiny, wind-dispersed spores that help it spread far and reproduce without seeds, an ancient adaptation.
- **Evergreen Toughness:** This clubmoss stays green all year round, even in winter, helping it absorb sunlight when other plants are dormant.
- **Creeping Ground Hugger:** It has a creeping stem system that helps it form dense mats, anchoring it firmly and protecting the forest floor.

## Measurements & details

- **Height:** 5-15 cm
- **Spread:** 30-100 cm
- **Edible:** No
- **Toxicity:** Mild
- **Lifecycle:** Perennial
- **Pollination Method:** Wind

## Ecological connections

- **Symbiotic with:** Arbuscular Mycorrhizal Fungus (*Rhizophagus intraradices*) — helps clubmoss acquire nutrients from soil
- **Eaten by:** [Red Deer](https://www.snappit.app/explore/red-deer) (*Cervus elaphus*) — may browse on its evergreen foliage in winter
- **Shelter:** Wood Mouse (*Apodemus sylvaticus*) — provides cover and microhabitat on the forest floor

## Traits

- [Grass-Like](https://www.snappit.app/explore/traits/grass-like): Grass-like plants are herbaceous plants that visually resemble true grasses, typically having long, narrow leaves.
- [Shade Tolerant](https://www.snappit.app/explore/traits/shade-tolerant): Shade tolerant plants are adapted to grow and thrive in areas with low light levels, requiring less direct sunlight.
- [Evergreen](https://www.snappit.app/explore/traits/evergreen): Evergreen plants retain their foliage throughout the year, never shedding all their leaves at once.
- [Spore Producing](https://www.snappit.app/explore/traits/spore-producing): Spore-producing organisms reproduce by releasing small, often single-celled, reproductive units called spores.
- [Ancient Lineage](https://www.snappit.app/explore/traits/ancient-lineage): This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years.
- [Decomposer](https://www.snappit.app/explore/traits/decomposer): Describes organisms that break down dead organic material, recycling nutrients back into the ecosystem.
- [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life.
- [Longevous](https://www.snappit.app/explore/traits/longevous): This trait characterizes organisms with an exceptionally long lifespan compared to others of their kind.
