Lacebark Kurrajong - Brachychiton populneus

The Lacebark Kurrajong, also called the "bottle tree" is a member of the Brachychiton genus of trees and native to Australia. It is a fast growing tree whose trunk tends to bulge a bit, although much less than some of the other "bottle trees" such as the Brachychiton rupestris. The new bark of the Lacebark Kurrajong is green in color and has photosynthesis capability. The bark turns light brown as it ages. As the trunk stretches however new bark is exposed in the stretch marks of the old which creates the "lacebark" pattern.
Like other Kurrajongs this tree species has a great deal variation in its leaf shapes. Leaf shapes vary from simple to multiple lobes. Three lobes are very common and I have seen some with five. It is also very common to see leaves that are asymmetrical with a lobe on one side missing or underdeveloped.
The seed pods grow in clusters of 4-5 pods is a sort of star pattern. Each individual pods has a sort of boat shape the eventually opens up revealing the corn kernel shaped seeds.
The seed pods also have an interesting ornamental value if you are into doing crafts.
The seeds are reputed to be edible although extracting them can be tricky. The inside of the seed pod is lined with very fine hairs that will stick in your skin if handled with bare hands.
