• Text: "The Berlin holotype (B-W 16422-01 0) is undoubtedly the plant that I accepted as Buphthalmum uniflorum Willd. (=Wollastonia uniflora (Willd.) Orchard), but the specimen BM (BM000820296) is equally undoubtedly Wollastonia lifuana (Hochr.) Fosb., endemic to New Caledonia and (perhaps) Vanuatu, and must be considered an excluded (mislabelled) syntype of Buphthalmum uniflorum and not an isotype. ... The specimen that I cited from the Paris herbarium (P698454) seems to be a good match with the Berlin specimen. It lacks a definite locality, although it is undoubtedly a Forster collection. It may therefore be an isotype of Buphthalmum uniflorum."
