Comments:
Heteropogon contortus (L.) P. Beauv. ex Roem. & Schult.
Pili is an indigenous perennial with erect tufted culms of around 50 cm and flowers that have twisted or contorted awns. In 1931 Caum reported this species as common, on the outer side of east horn, and scattered over the eastern half of the southern slope. He also noted that it grew very sparingly west of the median line. We found this species to be occasional on the eastern slopes of the islet and note that it is locally common along the upper southern slopes of the outer crescent where it reaches its greatest density.
