• Type: "Vict.: Lockwood, A.B. Braine; Hawkesdale, H.B. Williamson (in Syd. Nat. Herb., labelled C. pruinosa); Healsville, Mrs. Edith Coleman; Sherbrooke and Lorne, W.H.N.; Fern Tree Gully, F.J. Bishop; Gembrook, D. Matthews; Olinda, A.J. Tadgell. Tas.: Penguin, Archdeacon Atkinson; Hobart, Relbia, Launceston and Low Head, H.M.R.R. S. Aust.: National Park, Dr. R. S. Rogers in Syd. and Bris. Nat. Herb., labelled C. pruinosa)."

• Comment: Jones & Clements, loc. cit. state that "Van Royen (1983) gives Nash 981 (NSW) without reason as the lectotype. However, since Nash 981 was not cited in the original description, the choices of that collection as the lectotype cannot stand".
