Cycads are long-lived, slow growing plants that always occur as individual male or female plants (2) (7). There is no way of determining the sex of a cycad until it begins to produce its first cone (7). For a long time cycads were thought, like cone-producing conifers, to be entirely wind pollinated (8). However, studies now suggest that the vast majority, if not all cycads, are actually pollinated by insects or more specifically weevils (2) (7)
[ ] [(8)]. To attract pollinators, male and female cones produce powerful odours, usually in the early morning or evening (7). Travelling between the sexes, the weevils pollinate the plants by inadvertently transferring pollen from the male cones to the receptive ovules of the female cones (7) (9).
The seeds produced by cycads are large and have a fleshy outer coat, but are relatively short-lived and vulnerable to desiccation. The fleshy outer layer is desirable to a range of animals such as birds, rodents and bats, depending on the species of cycad and region it occupies. However, with any luck the unpalatable seed is discarded some distance away from the parent plant in a hospitable environment in which to germinate (2). The seeds of E. whitelockii are an important food source for baboons (10).
