AB - Cockayne proposed a nucleus of suitable species surviving the Mio- cene and diversifying afterwards in the mountains. P. Wardle suggested that this nucleus could have survived on a southern extension of the New Zealand archipelago into a temperate climate. It was suggested that only a few well-marked species would be needed to produce, in a genus, a large number of slightly differ- entiated species. The effects of the glacial periods on plant distributions were illustrated by several examples. It was shown that most of our large-leaved herbs now persist on outlying islands, perhaps indicating a larger-leaved preglacial flora on the mainland. With respect to earlier vegetation on what are now grasslands in eastern South Island, the work of Molloy and others in disclosing widespread soil charcoals indicates a woody vegetation in fairly recent times, but not perhaps continuous forest. A possible example of interaction between insect pollinators and flowers is seen in the gentians of our subantarctic islands, where pollinators are few. Populations on Campbell Island have up to 50% white flowers, the remainder showing various patterns of red pigment. On the other hand this may be a physiological response to subantarctic conditions, because flower pigmentation is acconl- panied
