Features of pollination in native fl owering plants
■ plan, choose equipment or resources and perform a fi rst-hand investigation to gather and present information about fl owers of native species of angiosperms to identify features that may be adaptations for wind and insect/bird/mammal pollination
Table 3.9 Features of native fl owers that may be adaptations for pollination
Feature of fl ower Scientifi c and common name of selected plant specimens
Banksia ericifolia (banksia)
Flowers No single fl owers but large number grouped together (infl orescence)
Sepals None
Petals Yellow
Scent Sweet
Nectar present
Anthers Brightly coloured
Stigma Long and above anthers
Type of pollination and justifi cation
Insect pollination because:yellow coloured petals suggest bee pollination, brightly coloured anthers suggest insect attractor, nectar reward for insects, and high number of fl owers allow many insects to pollinate at the one time
