Fruits collected from July to December.</p><p>Etymology.</p><p>The specific epithet honors Professor Richard Mark Kingsley Saunders, former professor at the University of Hong Kong, for his contribution to Annonaceae systematics, phylogeny, and pollination ecology.</p><p>Notes.</p><p>Van Heusden (1994) noted that Meiogyne cylindrocarpa specimens from Borneo and Sumatra differ from the New Guinea specimens in tree size, leaf shape, and flower size but dismissed these as infraspecific variation engendered by habitat, attributing the long caudate leaf apices of the Bornean and Sumatran specimens to a habitat with higher rainfall and concluding that “ the differences are not consistent enough to distinguish two species. ” However, several molecular phylogenetic studies have suggested that the West Malesian specimens should be regarded as a distinct species (Thomas et al. 2012; Xue et al. 2014, 2021; Jaikhamseub et al. 2022; Liu et al. 2025 d). The most densely sampled, well-resolved, and well-supported phylogeny of Liu et al. (2025 d) retrieved Meiogyne cylindrocarpa (as ‘ Meiogyne cylindrocarpa (Australia) ’) within the Australasia-Pacific clade, whereas Meiogyne saundersii (as ‘ Meiogyne cylindrocarpa (Borneo) ’) is nested within the early-divergent basal Asian grade (Fig. 1). Apart from the sharply defined differences mentioned in the diagnosis, Meiogyne saundersii also differs from M. cylindrocarpa in its monocarp length (10–17 mm long vs. typically 25–35 mm long, excluding stipe) and monocarp apex (typically contracted into a narrow beak 1–4 mm long, rarely rounded vs. typically rounded, rarely mucronately beaked up to 1.5 mm long). The habit of Meiogyne saundersii varies from treelets to trees up to 20 m tall, whereas Meiogyne cylindrocarpa varies from shrubs to treelets up to 6 m tall. Furthermore, the habitat and climatic niche occupied by the two species differ considerably, with M. saundersii occurring in tropical rainforests without a dry season and M. cylindrocarpa occupying forests and woodlands with a distinct dry season. The type of M. cylindrocarpa was collected from Merauke, a coastal area in Indonesian New Guinea with a pronounced dry season. Other specimens assessed to be conspecific were collected from East Java, the Lesser Sunda Islands, the Maluku Islands, southern coastal parts of New Guinea, the northern part of Western Australia, the northern part of the Northern Territory of Australia, the coastal areas of the Cape York Peninsula, and the Mariana Islands, all of which have a pronounced dry season, with the driest quarter receiving &lt;300 mm rainfall. The geographic distribution of the two species seems sound, as many plant species are restricted to either wet tropics or seasonal tropics (Crisp et al. 2009). Philippine specimens were not included in the concept of Meiogyne cylindrocarpa in van Heusden (1994), but Turner (2016) reduced the Philippine Alphonsea sessiliflora Merr. to synonymy of M. cylindrocarpa . More work is needed to assess whether the Philippine name requires recombination in Meiogyne, owing to the scarcity of specimens available. Oncodostigma wilsonii Guillaumin from Vanuatu is regarded by van Heusden (1994) as a synonym of Meiogyne cylindrocarpa, but we consider the species distinct and transferred it to Meiogyne (see below). Apart from being confused with Meiogyne cylindrocarpa (e. g., Turner 2014), herbarium specimens of Meiogyne saundersii are frequently misidentified as Alphonsea, Polyalthia, and Xylopia species. The morphological differences between Meiogyne cylindrocarpa, Meiogyne saundersii, and two other species treated below are summarized in Table 1.</p><p>Preliminary conservation status.</p><p>The species is rather widespread, with its EOO and AOO estimated at 1,422,770 km 2 and 100 km 2, respectively. Moreover, it grows in several protected areas (IUCN Category II: Gunung Mulu National Park, Gunung Palung National Park; IUCN Category Ia: Andulau Forest Reserve, Tangkulap Forest Reserve, Sg Imbak Forest Reserve; IUCN Category VI: Bukit Belata Forest Reserve).

(2025 d).</p><p>Notes.</p><p>Van Heusden (1994) considered this species a synonym of Meiogyne cylindrocarpa but noted that the Vanuatuan specimens differed in having globose (vs. cylindrical) monocarps. However, the immature monocarps of Meiogyne wilsonii are cylindrical (Fig. 2 F; Tuiwawa &amp; Munzinger 2956, Munzinger 3589), which might have influenced van Heusden’s decision to merge it with M. cylindrocarpa . Our observations additionally revealed that Meiogyne wilsonii has lanceolate leaf blades and a thick pericarp (c. 2 mm), whereas Meiogyne cylindrocarpa has broadly ovate, ovate, or elliptic leaf blades and a thin pericarp (up to 1 mm). A molecular phylogenetic study (Liu et al. 2025 d) indicated that Meiogyne wilsonii (as ‘ M. cylindrocarpa (Vanuatu) ’) is more closely related to the Fijian and Tongan Meiogyne species than to M. cylindrocarpa sampled from Australia, which is morphologically similar to the type of M. cylindrocarpa from New Guinea (Fig. 1). Meiogyne wilsonii is most similar to Meiogyne habrotricha (A. C. Sm.) B. Xue &amp; R. M. K. Saunders from Fiji in its subglobose monocarps, cordate leaf base, and pubescent branchlets but differs in its glabrous (vs. copiously velutinous-puberulent) monocarp and longer and thicker monocarp stipes (2.5–3.5 × 4–5 mm vs. 1–2 × 2–3 mm). See Table 1 for a morphological comparison between Meiogyne wilsonii and other morphologically similar species.</p><p>Van Heusden (1994) and Turner (2018) erroneously indicated that the P sheet is the holotype of Oncodostigma wilsonii, possibly because van Heusden annotated the P sheet as a holotype. However, Guillaumin (1931) did not indicate a particular herbarium in which the type was deposited in the protologue, and he manually annotated “ Oncodostigma wilsonii Guillaumin, sp. nov. ” on the A, BRI, and P sheets, suggesting that he likely studied all of them. The P sheet is selected here as the lectotype, as it is the only specimen with both mature flowers and fruits on the same sheet.</p><p>Preliminary conservation status.</p><p>This species is known only from the Vanuatu archipelago, where it is recorded from the northern island Espiritu Santo and the southernmost island Aneityum but not from the intervening islands (Fig. 7). Like New Guinea, Vanuatu is a poorly collected region (Plunkett et al. 2022), suggesting that the current data are likely insufficient for assessing its true distribution. Therefore, it is assessed here as Data Deficient (DD).</p></div>	https://treatment.plazi.org/id/72BA8028FC345E40BD3F39330674DDC4	Public Domain	No known copyright restrictions apply.

Kasmin 121 (holotype K [K 000260884!, K 000260885! – a single specimen over 2 sheets]; isotypes A [A 00549712!], BISH, BO, BR, CANB, Freeport, KYO, L [L. 3728206!], LAE, MAN, MO, NSW, SAN, SING [SING 0404965!], TI) . [Basionym]</p><p>Notes.</p><p>Examination of the protologue and type specimens of this species revealed that it possesses decurrent secondary veins, a single seed per monocarp, and elongated stigmas; these characters suggest that it should be placed in the genus Monoon (Xue et al. 2012) . Liu et al. (2025 d) sampled the paratype Dransfield 7692 (K!), and the phylogeny revealed that Meiogyne papuanum is nested within Monoon with maximum support. The majority of Monoon species in New Guinea have narrowly triangular to linear petals that are smooth on both sides (Ezedin 2025), but Monoon papuanum has ovate-triangular petals with verrucose bases on the adaxial surface of the inner petals. It is similar to Monoon pachypetalum I. M. Turner &amp; Utteridge and Monoon salomonicum I. M. Turner &amp; Utteridge in having broadly ovate to ovate-lanceolate petals and warty bases on the adaxial surface of the inner petals. However, Monoon papuanum is distinct from these species in its glabrous (vs. adpressed hairy or tomentose) monocarps. Additionally, Monoon papuanum has longer fruiting pedicels (up to 40 mm) than Monoon pachypetalum (up to 25 mm) and Monoon salomonicum (up to 18 mm).</p><p>Preliminary conservation status.</p><p>This species was provisionally assessed as Endangered (EN B 1 ab (iii)) by Turner and Utteridge (2015).</p></div>	https://treatment.plazi.org/id/7C38266E9C1E52C499FE8C7338B3BF90	Public Domain	No known copyright restrictions apply.
