Of the 27 unbagged inflorescences from which insect collections were made, 19 were males, six were females, and two were bisexuals. To exclude i nsect visitors, we completely covered 3-5 unopened inflorescences with mosquito gauze (mesh size: 1 mm). The final treatment was unmanipulated female inflorescences exposed to both wind and insect pollination modes (open pollination). Inflorescences per tree were quantified by counting the inflorescences of a representative part of the tree crown and then extrapolating to the whole crown. Floral odour production was assayed by enclosing several male and female inflorescences in separate test tubes for 1 h to let any fragrance concentrate. The hybrid material is highly feminine, and the rare male inflorescences that appear produce only a small amount of viable pollen. Moreover, we identify the volatile compounds emitted by the inflorescences that may be implicated in beetle attraction. In our sample, about 83% of species exhibited compound inflorescences, although it is not known how this compares to floras of other regions. Mean values of three control inflorescences from the same plant were used for statistical comparison. The wasps are deceived into pollinating the inflorescences on female plants, but fail to reproduce. In both cases, the infloresences are generally similar in size except for the peduncles of the male inflorescences which are longer than the female's. Such flowers in low numbers are easily overlooked among numerous male inflorescences and may be more frequent than reports suggest. Of the female inflorescences, c. 45% abort - 20.7 and 24.8% during the bud and the anthesis stages, respectively. Male inflorescences were not encountered on female individuals.
