Comment:The second volume of F.J.H. von Mueller's Pl. Indig. Victoria (1863) is not effectively published under ICBN Art. 29.1 (Vienna Code, 2006) as it was only issued as page proofs. See D.M.Churchill et al., Muelleria 4: 114 (1978) and A.B.Court et al., Nuytsia 9(3): 315-318 (1994) for a discussion.
