The primary habitat of Polycarpaea ebracteata is the hillock terrains in Palakkad district (Granite outcrop in the southern side of Palakkad gap, the largest break in the Western Ghats having an arid climate with seasonal fires, in the state of Kerala). One of the common species that emerges after the initial rain are members of the Genus Polycarpaea, especially Polycarpaea aurea (Wight 1850: 44) Dunn (1915: 65). Polycarpaea ebracteata is seen associated with Allmania nodiflora (L.) R. Br. ex Wight, Indigofera aspalathoides DC. and Fimbristylis cymosa R. Br.
