Plants within the family have been characterized as species which constitute tufts or have pendulous strands; stems are differentiated in a creeping leafless primary stem and an erect or pendent secondary stem: leaves vary in size and form, from ovate leaves with acute apex and plane margins to acuminate with serrulate margins.
Leaves are opposite or in whorls of 3, blades lanceolate to oblong and densely pubescent, rounded and then cuneate at the base, and crenate-serrate or closely serrulate on the margins except near the leafbase [106].
