摘要：
New Zealand's long isolation from other elements of Gondwanaland, oceanic climate, the unusual combination of ancient Gondwanic, tropical and more recently arrived elements in its flora, and its relatively depauperate pollinator and disperser fauna have set the stage for the evolution of a subtle, complex and distinctive reproductive biology. This contrasts markedly with the neighbouring continent of Australia where the fauna is diverse and the flowers vivid. Recent advances in understanding New Zealand's floral biology include evidence that the ancestor to the anthophytes was cosexual, with insect pollinators receiving stigmatic nectar rewards;the discovery of ground-level bat pollination in an obligate root parasite;the finding that the greater resource sensitivity of fruit set in males than in females may account for sex ratio variation in gynodioecious species;and, evidence for much more pronounced mast seeding at higher altitudes even in the absence of mammalian seed predators.
