Lepidocupania myrmoctona (Radlk.) Buerki, Callm., Munzinger & Lowry , comb. nov.

≡ Cupaniopsis myrmoctona Radlk. in Sitzungsber. Math.- Phys. CI. Konigl. Bayer. Akad. Wiss. Munich 9: 588. 1879.

Lectotypus (designated by ADEMA, 1991: 140; second step designated here): NEW CALEDONIA: sine loco, s.d., Labillardière s.n. ( G [ G00019027 ]!; isolecto-: FI [FI006799 FI006840]!, G [ G00341584 , G00341590 ]!, K).

Distribution and ecology. – Lepidocupania myrmoctona is endemic to Grande Terre, where it is abundant along the east coast and grows in dense humid forest, mostly on nonultramafic substrate (schist), but it has also been recorded in montane ecosystems in the main southern ultramafic massif ( ADEMA, 1991).

Notes. – Cupaniopsis myrmoctona was described based on “Labillardière (Hb. Webb, Hook., Deless.)” ( RADLKOFER, 1879b: 588). ADEMA (1991: 140) designated material from G as the lectotype. A second step lectotypification is, however, required because the original material at G comprises three sheets originating from three different herbaria: Delessert [G00019027], Moricand [G00341590], and Ventenat [G00341584]. Ventenat’s herbarium was originally part of the Delessert herbarium ( CALLMANDER et al., 2017) and both [G00019027] and [G00341584] are annotated in Radlkofer’s hand: “ Cupaniopsis myrmoctona m. Radlk.”. Here we designate the most complete and best-preserved sheet [G00019027], originating from the Delessert herbarium, as the lectotype.
