Spermacoce remota is a perennial herb or sub-shrub up to 70 cm tall. Stems are either round or square in cross-section. Leaves are lanceolate, up to 5 cm long. Flowers are small, white, in a clump at the top of the stem.^[5] This herb is a common ground for oviposition of butterfly eggs, such as those of Anartia fatima.
