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.</p><p>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 .</p></div>	https://treatment.plazi.org/id/843B87AF2244F92E84A6F94D50EDA7FF	Public Domain	No known copyright restrictions apply.

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.</p></div>	https://treatment.plazi.org/id/843B87AF2244F92E84A6FE115411A41B	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

The two Balansa collections were made above Conception, and the one sheet of Balansa 1030 with Guillaumin’s handwriting is chosen as a lectotype because it has well developed fruits. Two syntypes are excluded: Lecard s.n. (P-02582593!), which belongs to P. pancheriana s.s. and Le Rat 831 (P-02582588!) from “plateau de Dogny” (doubtful locality), which belongs to P. brachystachys .</p><p>This taxon displays a combination of characters of P. leratii (leaf mostly entire, inflorescences many, some inserted low on branches) and P. pancheriana (mostly glabrous, acuminate leaves). A hybrid origin comparable to that of Cunonia × koghicola H.C. Hopkins, J. Bradford &amp; Pillon (in Pillon et al. 2008: 423), which has a similar distribution, may be hypothesized (Hopkins et al. 2014).</p></div>	https://treatment.plazi.org/id/843B87AF2247F92D84A6FA385274A745	Public Domain	No known copyright restrictions apply.

A. Branch 2018	<div><p>Polyosma kouaouana Pillon, sp. nov (Figure 1)</p><p>A species most similar to Polyosma spicata in the size, shape and glaucous aspect of its leaves, and to Polyosma discolor in its near sessile fruits, but which differs from both by the leaf margin that is minutely toothed or sinuate and the leaf blade that is bullate.</p><p>Type: — NEW CALEDONIA. Kouaoua, Aréha, 500 m, 30 march 1982, McKee (leg. J.- F. Cherrier) 40295 (holotype P-04377521!).</p><p>Shrub 2–6 m tall, glabrous except on bud, with lenticels on younger wood. Leaves: pseudo-opposite, elliptic with rounded to pointed apex, base triangular, petiole 16–45 × 1–2 mm, blade coriaceous, bullate, 4.5–14 × 2–4.8 cm, lower surface glaucous below, margins with fine teeth (&lt;1 mm long) or sinuses; 6–13 pairs of secondary veins, convex below, concave above. Young inflorescences with very short shiny hairs, 3.5–7.5 cm long, bracts 2 × 0.2 mm. Flowers: pedicel c. 1 mm long; calyx tube c. 1.5 mm long with 4 spreading tips; corolla 2.5–3 mm long in bud; buds pinkish (fide McKee 9902), purple (H. Vandrot, pers. comm.) or reddish green (Barrabé 934). Flower at anthesis unkown. Fruits ovoid, 8 × 6 mm, glabrous, smooth, with 2 longitudinal furrows, pyrenes 2 per fruit, 7 × 4 mm. Seeds ellipsoid, 4 × 2 mm.</p><p>Ecology and conservation: —Unlike the morphologically similar P. spicata and P. discolor, this species occurs on ultramafic substrates in maquis and mountain forest, at 500–1000 m elevation. It is known so far from only 4 localities: Kouaoua (Aréha, Montmartre), Mé Maoya (ridge between Baraoua and Houailou rivers), Boulinda (pic Poya), and Paéoua (H. Vandrot, pers. comm.). They are all located within a 40 km radius. This patchy distribution is quite similar to that of Pancheria ajiearoana H.C.Hopkin, Pillon &amp; Bradford (2009: 442) . All populations may be directly affected by nickel mining, particularly the first one. This species will be assessed by the New Caledonia Plant Red List Authority and would likely qualify as Endangered EN B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) (IUCN 2017).</p><p>Paratypes: — New Caledonia, Kouaoua: décharge Montmartre, 14 february 1978, Veillon 3504 (P!) ; <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=165.76445&amp;materialsCitation.latitude=-21.441387" title="Search Plazi for locations around (long 165.76445/lat -21.441387)">Kouaoua</a>, Mine de Méa, décharge Montmartre, 165°45’52’’E, 21°26’29’’S, 723 m, 17 august 2009, Barrabé &amp; Nigote 934 (P!, K, NOU, NY, Z, S) ; Mt Boulinda, près du Pic Poya, 800 m, 7 november 1984, Veillon 5830 (P!) ; Crête entre la haute Houailou et la haute Baraoua (contrefort du Mé Maoya), 28 december 1962, McKee 9902 (P!) .</p><p>Notes: —the collection McPherson 2933 (P-04362121!) from Mount Mé Maoya is tentatively assigned to this species. It differs by its leaves that are more strongly toothed and more chartaceous. It could be juvenile foliage although this collection is fertile. The collections from the West (Boulinda &amp; Mé Maoya) look somewhat different from those from the type locality (Kouaoua), with leaves that are smaller, not so strongly bullate and the margin that is sinuate rather than toothed in Veillon 5830. Further observations are needed before deciding whether this taxon should be further divided.</p></div>	https://treatment.plazi.org/id/843B87AF2247F92C84A6FF98515EA6C0	Public Domain	No known copyright restrictions apply.
