Cochlospermum fraseri is a tree in the family Bixaceae with common names cotton tree, kapok bush, and kapok tree.[2] It is native to North Western Australia (in Western Australia[3] and the Northern Territory[4]).
Taxonomy
French botanist Jules Émile Planchon described this species in 1847 from Melville Island off the north coast of Australia.[5] Two subspecies are recognised: subspecies fraseri, found mainly from Katherine to Melville Island, has smooth leaves and 2 mm-long bracts, and supsecies heteronemum, from Katherine west to the Ord River, has finely furred leaves and 40-58 mm-long bracts.[4]
Description
Cochlospermum fraseri is a deciduous[3] tree or shrub which can grow to 7 m tall.[4] It flowers from April to October[4] (March to August[3]), the inflorescence being a terminal panicle.[4] The flower is asymmetric, having five sepals in two whorls, with the outer two sepals being shorter than the inner three.[6] It has numerous stamens.[4] The flowers often appear when the plant has no leaves.[7] It fruits from June to March, with the fruit being a woody capsule having 3 to 5 valves.[4]
Distribution and habitat
It is found in the bioregions of Central Kimberley, Dampierland, Gulf Fall and Uplands, Northern Kimberley, Ord Victoria Plain, Pine Creek, Victoria Bonaparte in the Northern Territory.[4], and the bioregions of Central Kimberley, Dampierland, Great Sandy Desert, Northern Kimberley, Ord Victoria Plain, Victoria Bonaparte in Western Australia.[3]
Cochlospermum fraseri grows in in open eucalypt woodland on a variety of soils, including sands, gravelly soils, and heavy clay soils.[4]
Uses
The indigenous people of northern Australia would eat the flowers, either raw or cooked, and the roots of young plants.[7]
