Response from Dave Albrecht:
Thanks for sending in the three Goodenia specimens. They do look quite like G.rotundifolia but are actually G.hederacea subsp. hederacea. The important feature to separate these two is the position of the bracteoles relative to the ovary. In G.rotundifolia the bracteoles are immediately below the ovary, whereas in G.hederacea subsp. hederacea they are some distance below the ovary.
I'll leave this one for someone more expert than me. It has not been recorded in our region before...... https://bie.ala.org.au/species/https://id.biodiversity.org.au/node/apni/2918127
