Synonymic references to the plant can also be found in literature, examples are Eleocharis macrostachya and Scirpus rostellatus.
Physical Characteristics
Physically, Eleocharis rostellata is characterized by elongated, green stems that can reach 30 to 100 cm in height. The plant has no evident leaves during the growing period. However, it bears spikelets at the tips of its stems, forming a clumped, reed-like appearance.
Identification of Eleocharis Rostellata
Successful identification of Eleocharis rostellata involves understanding and recognizing its growth pattern, leaf and stem structure, root and rhizome structure, as well as its flower and seed formation.
Growth Pattern
This perennial herb adopts a clump-forming growth pattern. It does, however, possess a cosmopolitan distribution, meaning it can grow almost anywhere in the world, granted the conditions allow.
Leaf and Stem Structure
Eleocharis rostellata is marked by altered leaf blades that form continuous sheaths around the stems. This unique structure creates a tube-like appearance and can make the plant seem leafless at first glance.
Root and Rhizome Structure
Eleocharis rostellata exhibits a fibrous root system. It possesses creeping rhizomes that allow it to colonize large expanses and establish in waterlogged conditions.
Flower and Seed Formation
Eleocharis rostellata is defined by cylindrical spikelets, which contain numerous spirally arranged flowers. It bears one seed per flower, ensuring ample reproduction and propagation.
Habitat of Eleocharis Rostellata
Eleocharis rostellata thrives in environments rife with water availability and can be found in wetlands, marshes, or water bodies like ponds and lakes.
Preferred Environmental Conditions
Three primary environmental conditions for Eleocharis rostellata include generous sunlight, consistently moist or water-logged soil, and mildly acidic to neutral pH levels.
Geographical Distribution
Eleocharis rostellata is native to North America, but it has developed a cosmopolitan distribution. It thrives in a range of environments from Europe to Africa and Asia.
Adaptations to Aquatic Lifes
Eleocharis rostellata’s fibrous root system and creeping rhizomes are adaptations that allow it to thrive in waterlogged conditions. The plant’s stem structure is also conducive to aquatic survival, facilitating gaseous exchange even in water submersion.
Life Cycle of Eleocharis Rostellata
Eleocharis rostellata follows a life cycle pattern involving vegetative growth, flowering, seed production, and dormancy.
Vegetative Growth
Eleocharis rostellata’s vegetative growth phase involves the expansion of its rhizomes, producing new stems and root systems. This growth phase is also key to the plant’s propagation efforts.
Flowering and Seed Production
During the flowering phase, Eleocharis rostellata begins producing spikelets which contain spirally arranged flowers. Once pollinated, these flowers yield seeds for dispersal and propagation.
Dormancy
In hostile environmental conditions, Eleocharis rostellata enters a period of dormancy where growth ceases altogether. The plant waits out harsh conditions and resumes growth once the environment becomes favorable again.
Ecological Importance of Eleocharis Rostellata
Eleocharis rostellata, despite its invasive tendencies, is ecologically crucial for a variety of reasons.
Role in Aquatic Ecosystems
Eleocharis rostellata provides physical structure to aquatic environments, creating habitats for different aquatic organisms. It also stabilizes the aquatic soil, reducing erosion.
