Romania #1868 (1966) – Spring Water-starwort (Callitriche verna)

Callitriche verna, commonly known as spring water-starwort, is an aquatic plant species that belongs to the family Plantaginaceae. This plant is native to various parts of Europe, North America, and other regions with temperate climates. It is typically found in freshwater habitats, especially slow-moving or still waters, such as ponds, ditches, and streams.

Here are some key characteristics and information about spring water-starwort:

1. Aquatic Nature: Spring water-starwort is an aquatic plant that primarily grows submerged in water. It may also be partially emergent, with some of its leaves and stems floating on the water’s surface.
2. Appearance: The plant has small, linear to lance-shaped leaves that are typically arranged in pairs along the stem. The leaves are often translucent and green, giving them a somewhat delicate appearance. The stems can be either floating or rooted in the substrate.
3. Flowers: Spring water-starwort produces tiny, inconspicuous flowers that are greenish in color. The flowers lack showy petals and are typically arranged in the leaf axils (the point where the leaves attach to the stem).
4. Habitat: This plant prefers shallow, clear, and nutrient-rich freshwater habitats. It can be found in various aquatic environments, including ponds, ditches, slow streams, and other water bodies.
5. Ecological Role: Spring water-starwort plays a role in aquatic ecosystems by providing habitat and cover for small aquatic organisms. It contributes to maintaining water quality by oxygenating the water and can help stabilize the substrate.
6. Reproduction: Callitriche verna reproduces through both vegetative means and by producing seeds. In some cases, it can form dense mats of vegetation that spread across the water’s surface.
7. Conservation Status: Spring water-starwort is not considered an endangered species. However, its presence in certain wetland habitats can be an indicator of good water quality, making it an important part of healthy aquatic ecosystems.
8. Use in Aquaria: Spring water-starwort is sometimes used in aquariums and water gardens due to its attractive appearance and its ability to oxygenate the water. It is considered a relatively undemanding aquatic plant in terms of care and maintenance.

Spring water-starwort, with its delicate and intricate appearance, is an interesting and beneficial addition to aquatic environments. It contributes to the overall health of freshwater habitats and can also serve as a visually appealing component of aquariums and water features.
