 Moreton-Bay (Leichhardt), Gympie (Bailey). In paludibus noa 

 salinis crcscit, Caules usque ad 5' alti, striolati, interduni uni- 

 sulcati, Vagina; ad basim cauhum arcte cylindrica^, aJ os trun- 

 catuui sa^pissime dense barbata^, folio lineari-subulato crassiusculo

 gemper ore barbata;. Racheolai flexuosa?- Anthera? perangusta^, 

 brevissirae mucronatffi, Stylus stigmatibus conspicuc barbeliatis 

 vix longior. Caryopsis pallida, linca brevior, pyriformi-ovata, 

 panlo angulata, rugulosa. 



Clar. Dallachy in raontibus pone Rockinj^ham^s Bay varictaicm

 vaglna infima floralis longe distat et vaeua manet, Plantam folils

 et sub nomine S. brachyphylli tunc distribui, Plantam similem,
