37 Facts About Selaginella

What is Selaginella?

Selaginella, often called spikemoss, is a fascinating plant genus with a rich history and unique characteristics. These plants are known for their resilience and adaptability, making them a subject of interest for botanists and plant enthusiasts alike.

1. Selaginella belongs to the family Selaginellaceae, which includes around 700 species.
2. These plants are often referred to as "resurrection plants" because some species can survive extreme dehydration and then revive when rehydrated.
3. Selaginella species are primarily found in tropical and subtropical regions, although some can thrive in temperate climates.
4. They are ancient plants, with a lineage dating back over 400 million years.
5. Unlike true mosses, Selaginella has vascular tissues, which help transport water and nutrients throughout the plant.
6. The leaves of Selaginella are small and scale-like, often arranged in a spiral or opposite pattern.
7. Selaginella produces two types of spores: microspores and megaspores, a characteristic known as heterospory.
8. These plants are often used in terrariums and as ground cover in gardens due to their lush, green appearance.

Unique Adaptations of Selaginella

Selaginella has developed several unique adaptations that allow it to survive in various environments. These adaptations make it a remarkable example of plant resilience and versatility.

9. Some species of Selaginella can curl up into a ball during dry conditions and unfurl when moisture is available, a process known as poikilohydry.
10. Selaginella can photosynthesize even at low light levels, which helps it thrive on forest floors.
11. The roots of Selaginella are adventitious, meaning they can grow from any part of the plant, providing stability and access to nutrients.
12. Selaginella has a unique type of chlorophyll, chlorophyll b, which allows it to absorb a broader spectrum of light.
13. Some species can tolerate high levels of heavy metals in the soil, making them useful for phytoremediation.
14. The plant's cell walls contain lignin, which provides structural support and helps it withstand harsh conditions.
15. Selaginella can reproduce both sexually, through spores, and asexually, through vegetative propagation.

Ecological Importance of Selaginella

Selaginella plays a significant role in its ecosystem, contributing to soil health and providing habitat for various organisms.

16. Selaginella helps prevent soil erosion by stabilizing the ground with its extensive root system.
17. The plant contributes to the formation of humus, enriching the soil with organic matter.
18. Selaginella provides a microhabitat for small invertebrates, such as insects and spiders.
19. The plant's dense foliage offers shelter and breeding grounds for amphibians and reptiles.
20. Selaginella can improve soil aeration, which benefits other plants growing nearby.
21. The plant's presence can indicate healthy, undisturbed ecosystems, as it often grows in pristine environments.
22. Selaginella can act as a pioneer species, colonizing bare or disturbed soils and paving the way for other plants.
