Cyperaceae - Cyperoideae - Abildgaardieae - Abildgaardia Vahl

Description:

  • Perennials, tufted
  • Culms with basal nodes
  • Leaves basal, eligulate; sheath with adaxial apex truncate, glabrous; blade linear, sometimes very short or 0, without keeled midrib, profile thickly crescentiform
  • Inflorescence a single spikelet, or capitate, or a simple anthela; subtending bracts foliose or scale-like
  • Spikelets of several subdistichous to spirally arranged glumes, basal few empty, up to 20 fertile, bisexual, upper few male or empty

  • Stamens 3
  • Style 3-branched
  • Nutlet obovate, triangular, smooth, warty or rugose

Classification Notes:

  • The problem of the interrelationship between the generic concepts of Fimbristylis, Abildgaardia and Bulbostylis is discussed by Lye: 539 (1971) and Gordon-Gray: 549 (1971) respectively
  • Lye took positive action by making transfers from Bulbostylis to Abildgaardia, whereas Gordon-Gray expressed reservations
  • Gordon-Gray (1995) has accepted the genus as here defined
  • Recently Lye: 108 (1995) has again accepted the genus Bulbostylis; the differences between Abildgaardia and Bulbostylis are summarised by Lye: 595 (1996)
