description

Austrobaileya scandens grows as an evergreen liana . It contains essential oils . The opposite , simple leaves are stalked, leathery and have entire margins . Stipules are present.

Hanging, large, hermaphroditic, screw-like flowers with a diameter of 5 to 6 cm arise individually from the leaf axils . The 12 to 24 free bracts are spread out and are of different shapes : The outermost are sepal-like and the further inside they are, the more clearly they have a corolla-like shape. There are six to eleven fertile stamens and a similar number of staminodes in each flower . The centripetally developing stamens are anthers embedded in connective. There are four to 14 (usually six to nine) upper, free carpels . Pollination occurs by insects ( entomophilia ).

The multi-seeded, ellipsoidal to spherical, orange berries remain united as a collective fruit and are about 8 cm long and 4 cm wide. The mealy to slimy endocarp is yellow. The seeds have a diameter of about 3 cm. The ripe, pumpkin-scented berries fall to the ground and are eaten by mammals or birds.

In terms of ingredients, lignans are particularly worthy of mention.

Systematics

There is only one species in the genus and therefore in the family:

  • Austrobaileya scandens C.T.White (Syn .: Austrobaileya maculata C.T.White ): This species only grows in the tropical rainforest of northeast Queensland in Australia on some mountains at altitudes between 380 and 1100 meters.

The Austrobaileyaceae family was listed by Léon Camille Marius Croizat in 1943 in Cactus and Succulent Journal (Los Angeles) , 15, p. 64. Austrobaileya scandens was published in 1933 by Cyril Tenison White in Ligneous plants collected for the Arnold Arboretum in North Queensland by SF Kajewski in 1929. In: Contributions from the Arnold Arboretum of Harvard University , 4: 29, t. IV first described. It turned out that the 1948 also by CT White in A new species of Austrobaileya (Austrobaileyaceae) from Australia. In: Journal of the Arnold Arboretum , 29 (3), p. 255 described the species Austrobaileya maculata is a synonym of Austrobaileya scandens CTWhite.
