Polyosma leratii Guillaumin (1920: 176) View in CoL ‘ Le Ratii ’.

Type:— NEW CALEDONIA. Plateau de Dogny, September 1909, Le Rat 825 (holotype: P-00537661!, isotypes: K-000739770!, P-00537662!, P-00537663!)

Polyosma leratii var. puberula Guillaumin (1939: 278) View in CoL ; syn. nov. Lectotype (designated here): − NEW CALEDONIA. s. loc., 24 september 1876, Lécard bois n°31 (P-00537660!). Syntypes: − forêts situées au sud de Canala, 1000 m, 20 November 1869, Balansa 1783 (P-02582511!, P-02582510!, P-02582512!) ; Lécard 93 (P-00639324!) ; possible syntypes: − Lécard s.n. (P-00639325!, P-00639326!)

Guillaumin (1920) cited a single collection in his description of P. leratii View in CoL : Le Rat 825. There are three sheets at P. One bears the handwritten “type” with Guillaumin’s signature, and can be considered as the holotype.

In his description of the variety puberula, Guillaumin (1939) cited two collections: Balansa 1783 and Lécard 93, bois n°31. Among several collections of Lécard at P, a single sheet bears the additive information “bois N°31” with the handwritten ” Polyosma leratii var. puberula ”, “type” and Guillaumin’s signature. It is therefore chosen as a lectotype. The variety name was not indicated in any of the sheets Balansa 1783 at P or the single sheet labelled “Lécard n° 93”. The variety puberula only differs from the typical variety by the pubescence of the inflorescence and this does not seem to correlate with ecology or geography. It is not maintained here as distinct.
