Identification Please

Posted by Wombat (My Page) on

I have uploaded a scanned image of some leaves to the Oz Garden Image forum under the heading "Identification Please".

The leaves are from 3 seedlings, trees I think, which have generously popped up in a section of my garden. This bit of garden had home-made compost dug in in spring and was mulched with the fine stuff from the bottom of a wood heap. This narrows the choice down to anything from a tropical fruit to an import from the wild :-)

The juvenile leaves, first 4 to 6, of all three were typical gum tree shape (the bottom leaf in the image is one) and then the leaf shape changed. One of the seedlings has the heavily indented maple-like leaf and the other two have the rounded, three lobe shaped leaf. The leaves are all thick and course like a gum tree but have no particular smell if crushed. The red colouring of the leaf stems seems to age quite quickly. The backs of the leaves are the same colour as the fronts and there is no difference in texture. The veins are quite prominent on both sides.

To give an idea of size, these leaves were scanned using a sheet of A4 paper as a background - the width of the image is the same as the width of the paper.

The stem beneath soil level neatly bulges out into an elongated oval (much like a stumpy carrot) for about 8 cms and the roots grew from the bottom.

I moved the three plants into pots and the move didn't seem to affect them at all.

I am intrigued with the difference in leaf forms and would love to know what they are.

A lot of wattles and eucalypts will start growing with small leaves that are completely unlike their 'adult' leaves. We have black wattles coming up all over our place - they start with ferny, fine leaves in in a month or so start growing they long, single leaves. The leaves have no smell when crushed. Could they be wattles?

These trees are Brachychiton populneus. They are very variable in the leaf shape. Great trees. Someone else may have some info they would like to share.

Thank you, Joylene. I had posted the same query on both this Forum and on Australian Natives and my mystery plants were identified very promptly - talk about service!!

No kurrajongs around here so I guess they came in via the wood heap.

They have been introduced to their new owner who will be taking them and the peppercorn tree which sprouted in a pot of aspidistras (wondrous things, wood piles and compost heaps) when, and if, the drought ends in our neck of the woods.

RE: Identification Please

Im doubtful as to these leaves being from Brachychiton populneus, yes, they are varied but the texture and pulvinul at the base isnt like a B.populneus.'

Did the seedlings have a slightly "fat" stem base?
