Distribution and habitat : Cyperus 
eboracensis is endemic to Queensland where 
it has been recorded from the Daintree River 
north to Moa Island (Map 2). Plants grow in 
dry sandy loams in eucalypt woodland. 
Notes : Cyperus eboracensis is distinguished 
within this group of species by the simple 
inflorescence, the unwinged culms and 
relatively narrow, proximal involucral bracts 
(1.5-2.8 mm wide). 
Etymology : From the Latin eboracum, the 
Romano-British name for York, England and 
-ensis, suffix indicating origin or place; the 
species is restricted to Cape York.
