Inundatus has leaves 1-3.5 cm diameter. Amphitrichus has leaves 1-10 cm diameter. What was the leaf diameter?
Petal length in amphitrichus is 3-5 mm, and in inundatus is 5-7 mm. The character that separates these two species in the keys in both Plantnet and Vicflora is the shape of the nectary (that produces nectar) at the base of the petals. This needs at least a hand lens to see. In inundatus, the nectary has a distinct llobe which is attached at its sides for at least half its length to form a pocket. In amphitrichus, the nectary has no lobe, but has a thick curved edge. You probably need to wait till it flowers and take photos of flowers front on and side on, and provide the measurement of petal length.
