Effectiveness of Distant Pollen Sources in Coprosma

Botany Division, Department of Scientific and Industrial Research, Christchurch

Abstract Plants of Coprosma are anemophilous and usually, though not invariably, dioecious. It is therefore of some interest that a strictly female plant of Coprosma propinqua in my garden regularly produces a full crop of drupes, and that numerous seedlings appear beneath it. At first, it was thought possible that apomixis was occurring, but the seedlings have proved to be a diverse lot. Some resemble C. cunning-hamii, proved by Allan (1926) to result from the crossing of C. propinqua and C. robusta, some are similar to smaller-leaved F2 plants (i.e. from open pollination among Fl) illustrated by Allan (1929), and some resemble the mother plant.
