Austrobaileya scandens C.T. White

Common Name:
Family: Austrobaileyaceae (Croiz.) Croiz.

Country of Origin: Queensland (Cook, North Kennedy)
Habitat: Daintree Rainforest endemic - Mesophyll / notophyll vine forest

Description: Evergreen, woody vines with loosely twining main stem and straight, leafy lateral branches endemic to the rainforests of northeast Queensland, Australia. This species is one of two species in the genus and the genus is the only member of the family, Austrobaileyaceae. It is a very primitive angiosperm family although it is sometimes placed in the Magnoliales (Cronquist) or Laurales. Cronquist considers it an "isolated small group, not wholly compatible with the bulk of either the Laurales or Magnoliales, but not sufficiently distinctive to constitute a family of its own."
The flowers are rather large, solitary in the axils of the leaves, with a putrescent odor, probably pollinated by flies.
Its pollen is the oldest recorded flowering plant pollen in Australia.

Culture: Austrobaileya foliage tends to 'burn' in direct sunlight, so it prefers to stay well beneath the rainforest canopy where it enjoys living in low-sunlight, wet and damp areas.
Also appears quite susceptible to burning from soaps, oils and emulsifiable carriers.
NOTE: "... Austrobaileya used to flower only sporadically in lower light and warmer conditions in the greenhouses. After placing the plant to a brighter position where it receives a slight winter chill (50F) nights the plant now flowers annually and quite prolifically...
