  • Botanical Name : Eragrostis tremula Hochst. ex Steud.
  • Eragrostis is derived from the Greek eros meaning love, and agrostis, grass, in allusion to the loose dancing spikelets. Tremula refers to trembling. The very slender pedicels which support the long spikelets, give rise to the constant tremulous motion shown by this species.

  • Plant Family : Poaceae (Gramineae)
  • According to the Rules of ICBN the names of the families should end in -aceae. Thus the new name for the family Gramineae became Poaceae. However, the name Gramineae is also exempted and conserved under 'Nomina Conservanda' because of their constant use for a long time.

  • Plant Form : Grasses
  • Occurrence (Special Areas) : Indroda Park
