Star fruit
Damasonium minus
Damasonium minus, commonly known as lesser water-plantain or Starfruit, is an aquatic plant species belonging to the Alismataceae family. As the name suggests, it is often found in aquatic habitats and is known for its distinctive star-shaped fruit. Here is an informative description of Damasonium minus, including its appearance, habitat, and ecological aspects:
Description:
-
Growth Form: Lesser water-plantain is an aquatic or semi-aquatic perennial herb. It typically grows in shallow water or mud.
-
Leaves: The leaves are basal and arise from the base of the plant. They are linear or lanceolate in shape and have parallel venation.
-
Inflorescence: The inflorescence of Damasonium minus consists of small, inconspicuous flowers arranged in a dense spike.
-
Fruit: The fruit is a distinctive star-shaped capsule, which gives the plant one of its common names, Starfruit. The capsule splits into several pointed lobes, resembling a star.
Habitat:
Lesser water-plantain is commonly found in aquatic habitats such as ponds, lakes, slow-flowing streams, and marshes. It can tolerate varying water depths and is often associated with muddy or sandy substrates.
Identification:
Identifying Damasonium minus involves recognizing its key features:
-
Aquatic Growth: It is primarily an aquatic or semi-aquatic plant, growing in or near water.
-
Linear Leaves: The leaves are long, narrow, and may have parallel venation.
-
Inconspicuous Flowers: The flowers are small and not showy, arranged in a dense spike.
-
Star-Shaped Fruit: The fruit is a distinctive star-shaped capsule, making it easily recognizable.
Ecological Significance:
