Species: Pseudostellaria jamesiana

James Stitchwort is a rhizomatous, perennial herb with weak stems that can easily be detached from the rhizomes; the stems are erect or ascending, 1.5-5 dm tall, and 4-angled with swollen nodes. The upper stem, inflorescence, and often the leaves have small, glandular-tipped hairs, while the lower stems are usually hairless. The leaves are opposite, stalkless, lance-shaped with long tapering, pointed tips, and 2-15 cm long by 1.5-20 mm wide. There are few to many flowers borne on diffuse branches arising from leaf axils and at the top of the plant. The flowers have five pointed sepals which are 3.5-6 mm long, green with pale, membranous margins, and covered with glandular hairs. Each flower also has 5 bilobed, white petals that are about twice as long as the sepals, usually 10 stamens, and a single pistil with usually 3 style branches. The mature fruit is shorter than the sepals and opens by 3 valves.
