Plant Characteristics and Structure

Growth Form:

Ludwigia palustris is a herbaceous perennial that exhibits creeping stolons, which are specialized stems that grow horizontally along the ground. These stolons allow the plant to spread and establish new roots, forming a dense mat that can quickly cover large areas. The plant’s herbaceous nature indicates that its stems are non-woody and relatively soft.

Morphology:

Leaves: The leaves of L. palustris are sessile, meaning they lack petioles or stalks. They are typically elliptic or ovate, with smooth margins and a pointed apex. The leaves are arranged alternately along the stems and can vary in size, ranging from a few millimeters to several centimeters in length.

Stems: The stems of L. palustris are slender, weak, and prostrate, meaning they lie flat on the ground or near the water surface. They are often branched, and the nodes, where leaves attach to the stem, may produce short rootlets. The stems can vary in color, from green to reddish-brown, and are covered in short, soft hairs.

Roots: L. palustris has a fibrous root system with numerous, fine, and branched roots. These roots provide anchorage for the plant and help in the uptake of nutrients and water from the soil or water column. The creeping stolons also produce adventitious roots at the nodes, which further contribute to the plant’s ability to spread and establish new individuals.
