REMARKS

Sebert was the principal author of “ Notice sur les bois de la Nouvelle Calédonie ” with the descriptive part written “en commun avec M. Pancher”. Authorship for names published in this book are usually, though not always, ascribed to Pancher & Sebert (http:// www.ipni.org, author search, 2 February 2007). These authors identified Fournier & Sebert (sic) 6 and Petit 6 as P. ternata Brongn. & Gris and gave a brief description of the plant, its wood and its uses .

Guillaumin (1921) considered that Pancher & Sebert’s plant was not identical to Pancheria ternata and so he named it as a new species, P. sebertii . He provided no description himself but his name is validated by reference to Pancher & Sebert’s publication. Although Pancher & Sebert did not intend to describe a new plant, their publication complies with Art. 32-45 of the Code and the specimens they cited are the syntypes of Guillaumin’s name. Sheets of these collections at P each have a label in Guillaumin’s hand indicating “ Pancheria seberti = Pancheria ternata Panch. et Seb. non Brongn. & Gris” and “type”. The specimen labelled “ Seb. et Fourn. 6 ” is chosen as the lectotype because it is fertile while Petit 6 is sterile. A sterile specimen at BM labelled “No. 6, Pancheria ternata ” could be an isolectotype, a lectoparatype, or neither.

Guillaumin (1921) mentioned two other collections as belonging to Pancheria sebertii , though they are not syntypes, Franc 1843 from Prony and Franc 226. He stated that the latter had been identified by Schlechter as P. ternata , but this appears to be an error as it is Franc 227 at P that was determined by Schlechter as P. ternata and redetermined by Guillaumin as P. sebertii .

Although the types of Pancheria sebertii and P.ternata are rather different from one another,both appear to belong to a complex species for which the oldest available name is P.ternata Brongn. &Gris. Variation in this complex will be discussed elsewhere.
