Webb in Connor and Edgar 1987 says "Ornduff, R. 1960 (T.R.S.N.Z. 88 : 63-77) recognised four subspecies in Senecio glaucophyllus Cheeseman. He described subsp. basinudus as new, and based subsp. raoulii on J.D. Hooker's S. lautus var. β Raouli pro parte. Ornduff noted that all of Hooker's specimens labelled "var. β Raouli" corresponded to his own concept of subsp. raoulii except the plant to which Spach apparently gave the manuscript name S. Raouli, which latter specimen was collected by Raoul at Akaroa. Ornduff regarded it as an erechtitoid Senecio. Ornduff selected a Colenso specimen (No. 4 on Sheet 3-H1232/55, Colenso No. 85) from Hooker's herbarium as the lectotype for S. glaucophyllus subsp. raoulii (Hook, f.) Ornd. Unfortunately, and as noted by Ali, S.I. 1964 (Austral. J. Bot. 12 : 282- 291), the Raoul specimen excluded by Ornduff must be the holotype of S. lautus var. raoulii Hook. f. as it is the only specimen mentioned by Hooker. This specimen Akaroa, Raoul (K!), is not an erechtitoid Senecio but a specimen of S. glaucophyllus subsp. basinudus Ornd. As Ornduff's S. glaucophyllus subsp. raoulii is based on Hooker's S. lautus var. raoulii it must have as its type the specimen Akaroa, Raoul. The two subspecies basinudus and raoulii are nomenclatural synonyms. As both species were published simultaneously neither has priority. The least disruptive procedure is to describe plants called subsp. raoulii by Ornduff under a new name."
