What are the morphological characteristics of this plant?

Lysimachia microcarpa has slender, upright stems that typically reach heights of 10 to 40 centimeters and bear small, bright yellow, five-petaled flowers. The leaves are arranged oppositely along the stem and possess an elliptical or lanceolate shape with entire margins. These leaves are generally much larger than the tiny, star-shaped blossoms that emerge from the leaf axils. The plant often features a creeping rhizomatous root system that allows it to spread through moist habitats. Small, capsule-like fruits develop following pollination to facilitate seed dispersal.
