===Pollination: ===
A recent study into the pollination of female ''L. peroffskyana'' cones, by John Hall, in the
form of a thesis which comprised an integral part of his Batchelor of Science (Honours) degree
(Department of Botany, University of Queensland), has proven beyond doubt, as a result of observations
and experiments, that ''L. peroffskyana'' is pollinated exclusively by host specific ''Tranes sp''.
weevils, which breed in the male cones and "which visit the female cones in large numbers."
In his thesis "Reproductive Ecology of the Australian Cycad Lepidozamia peroffskyana: A Host-Specific
Pollination Between a Cycad and a Weevil", John stated that:
"The cycad ''Lepidozamia peroffskyana'' is pollinated exclusively by the host specific Tranes
weevils which carry out their life cycle within the tissues of the male cone and which visit female
cones in large numbers. The results of the pollinator exclusion experiment (......) clearly indicate
that when Tranes weevils are excluded from ''L. peroffskyana'' female cones, the pollination of
ovules is essentially reduced to zero. Although several insects exploit ''L. peroffskyana'' as a host
plant (......) only Tranes weevils are associated with both male and female cones, and hence they
represent the only possible candidate for the insect pollination vector."

John also found that:

<ol><li> Tranes weevils congregated in spectacular numbers on male cones of ''L. peroffskyana'' some 24 hours before the cones commence to distend; and that one male cone collected for dissection was found to contain more than 700 weevils,
</li><li> that airborne pollen was not consistently recorded beyond a 2 metre radius surrounding the pollen shedding male cones,
</li><li> that the pollination of ''L. peroffskyana'' cones was effectively zero when Tranes weevils were successfully excluded from gaining access to female cones,
</li><li> that the results of his study: "unequivocally demonstrated that wind plays no role whatsoever in the pollination of ''L. peroffskyana''."
