ζceratocephalus pungens
ζCeratocephalus pungens Garnock-Jones ζ was described recently from specimens collected in the driest parts of S. Canterbury and C. Otago. It is a minute annual herb with deeply lobed finely lanate lvs, small sessile or subsessile fls, and heads of small dark achenes with spinous beaks (see, Garnock-Jones, P. J., New Zealand J. Bot. 22: 135-137 (1984)). The sp. has been known in N.Z. as C. falcatus and Ranunculus falcatus and was previously treated as naturalised.
