crellow's Identifications

Seen at the end of the flowering season, this species is apparently particular to Jervis Bay and is recognised by petals that are very round and spaced out further than other tea-trees. Seen throughout the park but also at B. Botanical Gardens. This photo was taken in the wild.
Hoping a specialist will co-identify but the species list at the B. Botanical gardens indicated L. epacridoideum when I first thought it was L. rotundifolium.
