Actually an interesting identification challenge sapling of a rainforest tree species in the Sapindaceae plant family. For me to focus some work on. First impression, from many years experiences in Qld and NSW: Looks like, perhaps a species of the genus: _Sarcopteryx_ , eg. local native in the region there _Sarcopteryx_stipitata_ –not confirmed.
Or alternatively, in my first impression less fitting, perhaps a species of the genus: _Mischocarpus_ , or _Alectryon_ , or _Guioa_semiglauca_ .
Notable part of observing this: Please notice the compound structured, pinnate arrangement, leaves, having multiple, separated, alternately arranged, leaflets. And the nearly obscured characteristic of this botanical family, compound leaf, rachis end–tip extension beyond the last leaflet's attachement.
@Purschy any more photographs please? I'm looking for a clear, close-up, leaflet underside macro setting photograph, in which i can attempt to see domatia, please. –or if you check for domatia and record so in a note in this sighting please.
