Ludwigia pilosa,[1] the hairy primrose-willow, is a species of plant in the family Onagraceae.

Description

[edit]

This aquatic plant is perennial and flowers through late June until late November.[2] Ludwigia pilosa is pubescent all over and sometimes described as velvety.[3] The stem can measure up to 1.2 meters tall with alternating leaves.[4][5] Leaves are simple and attached at the petiole.[5] Leaves are also elliptical shaped, gauging roughly 20 - 100 mm in length and 3-14 mm in width.[4][5] The flowers are characterized by no petals but having 4-7 yellow sepals averaging 4-5 mm long.[4][5] Ludwigia pilosa is plentiful in seeds measuring 0.5mm and incapsulated in a dry seed pod.[4] The seed box in cubed shaped with a thick exterior and estimates 3-4 mm in length.[4] Ludwigia pilosa has proven to be a very resourceful plant. Waterfowl feed on the seeds of the hairy primrose-willow and the immersed portion creates habitat for many invertebrates.[4] Once the plants start to decay, the detritus then sustains the invertebrates also.[4]

Habitat and distribution

[edit]

Ludwigia pilosa prefers wet ground and can be found along road side ditches, ponds, and shallow swampy areas.[4] Distribution spreads from eastern TX to the southern half of MS, AL, GA, NC, SC, the northern portion of FL, and two counties in southeastern VA.[6][2]
