Thank you Jean-Philippe Basuyaux, Tony and Jenny Dominelli & Arthur Chapman for confirming the id of this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Riverland and elsewhere
All our Senna's start growing the pods from the centre of the flower as soon as the flower opens.
It's a thin green bent stalk in the middle. As the flower is pollinated and so dies and falls off around the stem, the pod continues to grow.
Thanks to Arthur for highlighting the fact that S. a. ssp zygophylla only has 2 pairs of leaflets. As such we thought the narrow leaflets here were S. a. ssp zygophylla.
Arthur also explained that S. a. ssp coriacea is a natural hybrid, and so very variable.
It is possible, in the leaf comparision shot, that the left most leaf is S. a. ssp zygophylla. But until we find the bush again, and re-do the shots with sizes, etc, we can't be sure.
