Fontainea picrosperma is a species of the genus Fontainea withinthe milkweed family (Euphorbiaceae). It is endemic to the northeastern part of the Australian state of Queensland .
description
Vegetative characteristics
Fontainea picrosperma grows as a shrub or tree . There is a watery, red milky juice present.
The alternate and spirally arranged leaves on the branches are divided into a petiole and a leaf blade. The simple leaf blade is 7 to 15 inches long and 2 to 5 inches wide. The leaf surfaces are dotted with glands , while the oil glands are almost visible to the naked eye.
Generative characteristics
Fontainea picrosperma is dioeciously segregated ( diocesan ). The densely white woolly hairy petals are 5 to 6 millimeters long in the male flowers and 7 to 8 millimeters long in the female flowers. The disc is orange in color. The ten scars look like octopus arms .
The single-fan and single-seeded stone fruit has a length of about 25 millimeters and a diameter of about 20 millimeters. The hard and very thick endocarp is star-shaped and often five-pointed in cross-section.
ecology
The cassowary and the musk rat kangaroo have been seen eating fallen fruit.
Occurrence
Fontainea picrosperma is endemic to the northeastern part of the Australian state of Queensland . It occurs only in the Atherton Tableland at an altitude of 700 to 1000 meters. Fontainea picrosperma thrives in the undergrowth in the well-developed rainforest.
Taxonomy
The first description was 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 , Volume 4, p. 55. The type material was published in 1929 by S. Frank Kajewski in Boonjie, Atherton Tafelland collected in the rainforest at an altitude of about 700 meters and herbarium material with flowers deposited under the collection number 1262 in Harvard University Herbaria (Harvard University Herbaria Barcode 00048012).
use
The medical effects are still largely unknown.
Individual studies
In October 2014, researchers at the Berghofer Medical Research Institute, Brisbane , published an animal study on the cytostatic effect of an oncological preparation containing an active ingredient (EBC-46) from the seeds of Fontainea picrosperma .
