Zornia 
on sandstone in the Edith Falls to Waterfall Creek 
area. A type specimen at DNA of Z. oligantha 
S.Reyn. & Holland from Cobourg Peninsula does 
not fit the original description. Also, additional 
collections from that area link the type of 
Z. oligantha with Z. prostrata and show continuous 
variation in the pod and other characters used to 
separate the two species. The species growing 
in Darwin lawns and formerly included under 
Z. oligantha appears to be a distinct taxon and is 
treated below.
