• Text: "Typification: Cowan (1996) selected as the lectotype of Neptunia major, a fruiting specimen at K collected at Rockhampton by John Dallachy. Two specimens similar in appearance, both bearing ripe fruits and collected from Rockhampton are present at P. The specimen P 02735402 is attributed to “Ferd. Mueller” because it is Mueller’s name that appears on the printed label, but Mueller never visited Rockhampton, and the specimen was almost certainly collected by Dallachy. The sheet has two Neptunia branches mounted on it. The one on the right is N. major; the one on the left is N. gracilis. P 02735403 (right-hand branch) is without collector, but it matches the other specimen very well and looks like a duplicate of the other. The two branches on the left, from “between the Darling and Coopers Creek” appear to belong to N. heliophila. The specimen at MEL has a mounted branch bearing leaves and flowerbuds and there are several mature fruits in a fragment packet. It bears a handwritten label by Dallachy giving the collection date as December 26, 1862."
