Type:— NEW CALEDONIA. s. loc., s. dat., Pancher & Sebert s.n. (not found) Polyosma podophylla Schlechter (1907: 117) . Lectotype (designated here):— NEW CALEDONIA. Auf den Bergen bei Oubatche, 1000

m, 20 December 1902, Schlechter 15515 (B-100278232!, isolectotypes A-01154252, B-100278231!, BR-699842!, E-00265564!,

FI-014506!, G-00388957!, HBG-517024!, K-00739769!, L-0035079!, M-0242296, P-00537659!, S- 09-11256!)

The protologue of P. discolor indicates “Oritur in Austro-Caledonia, ubi leger. cl. Pancher et Sébert (herb.)”, but the type specimen of this taxon could not be located at P. There is no reason to believe that it should be located elsewhere since both Pancher and Baillon were affiliated to P. Type material of Polyosma pancheriana , described in the same publication, and also a collection of Pancher, is at P. The specimen may be simply misfiled, particularly after the recent refurbishment of this herbarium, and a neotype will not be designated at this time. The specimen Balansa 1780 (P-02582518!) bears the handwritten “est? mon P. discolor de herb. Sebert”, which suggests that it has been seen by Baillon.

In his description of P. podophylla, Schlechter (1907) cited a single collection, N ° 15515. There are apparently two sheets at B, both with “ Polyosma podophylla n. sp. ” handwritten, but with two different inks. One bears the note “acc. 22.XII.1903 ” (B-100278232) and the other “acc. 13. I.1908 ” (B-100278231). The first one, which is also a better specimen, is chosen as a lectotype. I follow Guillaumin (1920, 1939) in treating P. podophylla as identical to P. discolor .
