Abstract:                                                                                                                                                                                                                                                                                                                                                                                                                                    The age and correlation of the fresh-water deposits, in part the coal measures, have long been a problem in New Zealand geology. Recent detailed mapping of Cretaceous and Tertiary marine beds has provided much stratigraphic information, but has not led to any certainty as to the age of the fresh-water beds. Such beds rarely have marine beds both above and below, and seldom contain interbedded marine deposits. "Fresh-water beds" is used in this bulletin as a general term for all fluviatile and lacustrine deposits. The term "coal measures" is best restricted to those with workable coal seams. Floras from 110 localities ranging in age from Jurassic to Pleistocene have so far been examined. Floras from some localities have been studied in detail, but others have received only a preliminary examination. This bulletin includes systematic descriptions of plant microfossils and a statement of the evidence for subdivision and correlation of fresh-water beds that will serve as a basis for future work.
