It is quite common, but forest habitats can be impacted by humans due to farming or infrastructure constructions, sometimes harvested in small amounts for medicinal use. Further surveys are needed to understand the threats at the type locality and if the species is distributed outside the current area, and until these data are obtained, the species is assessed as Data Deficient (DD) (IUCN Standards and Petitions Committee 2024).</p><p>Additional specimens examined</p><p>(paratypes). VIETNAM, Lam Dong Province • Da Hoai District, Ha Lam commune, 17 September 2023, Tran Hung et al. DVH 17092023-1 (HN, IBSC) • Trieu Hai Commune, 17 September 2023, Tran Hung et al.

DVH 17092023-3 (HN, IBSC) .</p><p>Notes.</p><p>The exact placement of the subgenus of the new species is not easy, and sometimes confusing. At first we thought it belonged to the subgen. Akomos, which is characterized by inflorescences that are always terminal or both terminal and axillary, on branches with spirally arranged leaves, with inflorescences at the distal portion of branches often without subtending leaves and distinctly pedunculate; leaf margin usually entire, sometimes dentate in the upper part; and the plants drying brown to chocolate-brown; calyx with lobes spread out at anthesis, little or not imbricate, plants generally scaly (Hu and Vidal 2004). However, after a detailed examination of the specimens and descriptions of the species, we found that the described species has the following characteristics: the sepals are overlapping (Fig. 2 J, K), and young stem pubescent; old stem smooth; the lateral inflorescences arising directly from the main stem (Fig. 2 A), serrulate teeth toward the distal part of the margin (Fig. 1 C). These features are consistent with the subgen. Tinus Mez (Hu and Vidal 2004; Utteridge et al. 2023).</p><p>Under Ardisia subgen. Tinus, Vietnam has 14 species (Hu and Vidal 2004; Lien 2002, 18 speices in Thailand (Larsen and Hu 1996). This new species is distinct from all known species of the subgen. Tinus . Among them, the new species has the most similar characteristics to the two species A. albomaculata and A. brunnescens (subgen. Akomos). In addition to the characteristics of different subgenera such as indumentum, sepals, inflorescens, it differs from A. albomaculata in the leaf texture, venation and position of inflorescence (i. e., subcoriaceous; lateral veins 12–18 pairs, irregularly spaced, with short intersecondary veins, slender, distinct but shorter than lateral veins, angle to the midrib about 45 ° - 50 °; inflorescence extra axillary, condensed racemose). It differs from A. brunnescens by the indumentum on leaves, calyx (i. e., adaxial surface glabrous, abaxial surface copiously rusty villose especially on the midrib, and with many glandular dots). The detailed comparison between A. dahoaiensis, A. albomaculata and A. brunnescens is given in Table 1.</p><p>The new species has an unusual feature in that, besides the usual pentamerous flowers with five sepals and corolla lobes and five stamens, hexamerous-heptamerous flowers were frequently observed, possessing six to seven sepals, corolla lobes and stamens. This feature is different from A. albomaculata (5 - merous flowers). Furthermore, the population of this new species is quite close geographically to the A. albomaculata, distributed in Dong Nai province. However, the new species also has a different fruiting season compared to A. albomaculata (March). In addition, A. albomaculata also has the distinct characteristic of having scaly sepals (as observed from the type specimens [P 00075000, P 00087802] placing it in subgen. Akomos [Hu and Vidal 2004]). Taken together with the morphological differences from known species, it is apparent that the newly collected material indeed represents a species new to science, which we compared in detail to A. albomaculata and A. brunnescens and described here as Ardisia dahoaiensis D.
