General/Distribution: A family with 13 genera and about 1150 species (Willis, Dict. Fl. Pl. & Ferns. 429. 1973), chiefly tropical or subtropical in distribution. Eriocaulaceae is related to Commelinaceae, but is considered to be more advanced. The Xyridaceae, Rapatiaceae and Eriocaulaceae are considered the ‘Compositae’ of the Monocotyledons (Hutch., Fam. Fl. Plants. 32.1973). Represented in Pakistan by a single genus.
