- Deciduous shrub or tree.
- Size: 1 – 6 m high.
- Leaves: Large lobed leaves.
- Flowers: Bright yellow with 5 petals.
- Fruit: After the yellow flowers are pollinated, large, globular, green, papery fruit develop. The fruit capsules are egg shaped and 6 – 10cm long. They eventually turn brown and split along the seams to release their seed. The small black seeds are woven in a dense mat of fine silky hairs.

ClimateWatch Science Advisor
We expect plants to start shooting and flowering earlier in the year as a result of climate change warming the Earth. They may also start appearing in new areas, as warmer temperatures enable them to live in environments that were previously too cold for them.
When To Look
- March to August for flowering
Where To Look
- Kimberley region of Western Australia, and commonly sighted in Kakadu National Park in Northern Territory.
- In a variety of drier habitats.
The map below displays the accumulated observations of these species as reported by ClimateWatch observers, together with the layer showing how the range of the species might change between now and 2085, with orange areas indicating where the species might disappear, and green areas where the species range might expand.
C. fraseriis distinguished from C. gregorii (also from NT and Qld) in that it has leaves divided to the base rather than shallowly to lobed, while C. gillivraei has more deeply lobed palmate leaves. C. gillivraei occurs further east, in eastern NT and Queensland
