In addition, for seven other genera we suggest that the colonizers were likely insect pollinated and that on the islands they have become, of necessity, wind pollinated (Azara, Drimys [Fig.
1985; Philipson, 1946, 1947a, 1948), or de novo from buds in the axils of leaves or bracts, as in Acacia baileyana (Derstine & Tucker, 1991) and Drimys winteri (Tucker, 1959).
The inflorescences of Drimys winteri have acropetal floral initiation, but the direction of anthesis among flowers is basipetal (Tucker, 1959).
