  Description - A lax, often decumbent perennial 40 to 80 cm. tall, with flat blades and narrow, rather diffuse panicles 10 to 20 cm. long, the capillary branches verticillate; spikelets awnless, the palea none.

• Discussion

  The original description of Vilfa elegans states that the palea equals the lemma, but in the type in the Paris Herbarium the palea is obsolete.
