A small geuus of Australian, Tasmanian, and New Zeaiaud Grasses, doseiy allied to Tetrarrhena, diifering
from it k the long villous pedicel lo the florets, which are thus separated from the small glumes, as also by the
narrow awned palea of one or both ot the nenter flowers, the linear, hyaflne, upper palea of the terminal flower and
the Knear, compressed caryopsis; the stamens are four. (Name from p.apos. mall, .aud yW a . a coverm'g¡ iu
