Comprehensive DescriptionRead full entry
DescriptionThis adventive annual plant is prostrate or spreading, producing stems up to 20" long. There is very little branching of the stems, except at the base of the plant. The stems are light green to reddish purple and have conspicuous lines of white hair, although older stems become glabrous. Rather widely spaced along these stems are pairs of opposite leaves. Each leaf is ovate, glabrous, smooth along the margin, and up to 1/2" long and 1/3" across. The older leaves near the base of the plant have ciliate petioles, while the younger leaves are sessile, but larger in size. A small cluster of about 3-6 flowers occurs at the end of each stem. This flower cluster is subtended by leafy bracts. Each flower is about 1/8" long, consisting of 5 green sepals that are lanceolate, 3-10 stamens, 3 styles, and no petals. The pedicel of each flower is rather short and pubescent. The blooming period occurs during the spring and lasts about 3 weeks. Each flower is replaced by an elongated seed capsule containing numerous tiny seeds. The root system is shallow and fibrous. This plant spreads by reseeding itself, and it can also spread vegetatively by forming rootlets at the leaf nodes.
