A note on stamen position and petal number in Loranthaceae

Stamen position in Loranthaceae is summarized in both the Old and New Worlds. In the former, stamens are inserted on petals at the same height in an individual flower, with very few exceptions that appear to be in basalmost genera only. In the Americas, much diversity exists in both the position and the within-flower shapes of stamens, phenomena that occur in many genera, Psittacanthus showing the greatest diversity. The dimorphic, or at least the biseriate condition is believed to be the plesiomorphic state. Some comments are added on petal numbers in the family.
