First Leaves

The various seedlings are starting to grow their first sets of leaves after the cotyledons (seed leaves). Here are the Eucalyptus viminalis (manna gums). Their cotyledons were quite large and kidney-shaped, but their leaves are longer and slimmer:
The cotyledon of the Acacia melanoxylon (blackwood) was not distinctive, but the leaf more obviously belongs to a wattle.
The first leaves of the Eucalyptus ovata (swamp gums) are more rounded than those of the manna gum:
They will definitely have to be thinned out soon.  They have had a huge germination rate, although strangely there are 4 tubes where none have come up.
