More than symbioses : orchid ecology ; with examples from the Sydney Region
, 2013 The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

Review of the Breeding Systems of Wild Roses (Rosa spp.)
, 2009 The hips of wild roses (Rosa spp.) contain many healthful compounds such as vitamins and antioxidants. There is great interest in commercial cultivation but before this can occur, questions regarding plant reproduction and pollinators need to be ...

Evolution and functional significance of enantiostyly in flowering plants
, 2002 Enantiostyly is a plant sexual polymorphism in which the style is deflected either to the left or to the right side of the floral axis. Although enantiostyly has been recognised since the 1800s, little is known about this polymorphism.

POLLEN CARRYOVER, GEITONOGAMY, AND THE EVOLUTION OF DECEPTIVE POLLINATION SYSTEMS IN ORCHIDS
Ecology, 1999 Geitonogamy (transfer of pollen among flowers on the same plant) may lead to reduced outcrossing and interfere with sex function. Orchids with pollen packaged into pollinaria would be expected to be particularly vulnerable to the loss of cross-mating opportunities imposed by geitonogamy.
