Lucky it is the species of naturalised Lotus in the ALCW area that has eight or more flowers in the cluster. To ID other two I would need field notes or good photos of a calyx (which cups the flower) and information about hairiness and details of the hairs on the leaves and stem.
Thanks Betty and Don. You are legends. I'll try to take better pics from now on rather than happy snaps. Tks for your previous photo tips. I have your latest books which are a very useful resource!
