Definition of Eleocharis flavescens

Eleocharis flavescens is a perennial aquatic plant belonging to the sedge family, Cyperaceae. Recognized for its distinctive arrangement of green stems that form a grass-like appearance, its distinguishing characteristics make it prevalent in a variety of habitats, including both freshwater and saltwater environments.

Taxonomic classification

As a member of the plant kingdom, the taxonomic classification of Eleocharis flavescens falls under the order Poales, and within the family Cyperaceae. Its genus is Eleocharis, and the species is denoted as E. flavescens. Like all plants, it falls under the domain Eukaryota and is classified within the plant division Magnoliophyta.

Common terms used to refer it

Commonly, you may find Eleocharis flavescens referred to as Yellow Spikerush or Pale Spikerush. The term โ€˜spikerushโ€™ originates from its distinctive growth habit, which typically resembles spikes of grass, a common characteristic of many species in the Eleocharis genus.

Regions where it naturally grows

Eleocharis flavescens naturally thrives in a wide array of regions worldwide, from North America to Europe, Africa, and parts of Asia. It can typically be found in damp to wet soils around lakes, ponds, stream margins, wet meadows, and marshes.

Morphology of Eleocharis flavescens

Eleocharis flavescens exhibits a range of features consistent with emergent aquatic vegetation, adapting to both freshwater and saline environments. Its morphology is defined by various parts such as the stem, leaves, root system, and flowers and fruits.

Characteristics of the stem

The stems of Eleocharis flavescens are cylindrical, often standing upright and rooting at the base. They can be smooth or slightly rough to the touch, measuring between 20 to 80 centimeters in height and 1-2 millimeters thick, with no leaves present.

Details about leaves

The leaves of Eleocharis flavescens are reduced to mere sheaths that envelop the lower parts of the stem. These sheaths are often brownish to chestnut colored and truncated at the tip without any distinct shape.

Features of the root system

The root system of this plant is fibrous and rhizomatous, enabling the plant to form colonies under favorable conditions by re-rooting from the basal nodes. This characteristic aids in its effective colonization of various water bodies where it naturally occurs.

Description of flowers and fruits

As for reproductive organs, the inflorescences of Eleocharis flavescens occur singularly at the tips of the stems, usually comprising 4-25 spikelets. These tiny flowers give way to fruits, which are small, ovoid-elliptic achenes covered in minute warts.

Life Cycle of Eleocharis flavescens

The life cycle of Eleocharis flavescens begins with seed germination, followed by various stages of growth and development.

Periods of seed germination

The germination process commences when conditions become optimal, which usually occurs during the beginning of the wet season. The seeds will then start to sprout, taking in water from the soil and expanding as the embryonic plants grow.

Growth and development stages

As the seedlings emerge, Eleocharis flavescens enters the vegetative growth stage. It grows rapidly, quickly building an extensive root system, and starting to form stems and leaves in just a few weeks.

Reproductive phase

Following vegetative growth, Eleocharis flavescens enters the reproductive phase. This is marked by the development of inflorescences, yielding tiny flowers which are then pollinated. After successful pollination, these flowers give way to fruits that contain the seeds for the next generation.

Dormant period

During unfavorable conditions, Eleocharis flavescens may enter a dormant period. During this stage, all growth and development are halted, and the plant focuses on preserving energy. Dormancy is broken once conditions become favorable, allowing Eleocharis flavescens to resume its normal life cycle.
