A weedy evergreen vine or shrub which lays over. It grows to 70 cm high. It spreads about 50-200 cm wide. The stem is slender, creeping and twining. It has a large root system. The leaves are dull green and in opposite unequal pairs. They are 1-2.5 cm long by 1-2 cm wide. The lower leaves are broadly oval while the upper leaves are more narrow. The edges of the leaves are wavy. The flowers are yellow and white or pink. They occur in groups of 3 at the ends of branches. They are 0.5 cm long. The fruit are about 0.4 cm long. They have glands that make them sticky. In a similar plant Boerhavia erecta the fruit are smooth and not sticky.,
