Young twigs terete, grayish brown, glabrous, ca. 1 mm in diam., old twigs grayish brown, internode (0.5–) 1.2–2.6 cm long. Leaves opposite, blade elliptic, elliptic-oblong, rarely obovate, (1.7–)2.6–7.2 × (0.8–)1.2–2.7</p> <p>cm, 1.8–3.2 times longer than wide, coriaceous, dark yellowish green to grayish green adaxially, dull brownish yellow abaxially, glabrous on both surfaces, base cuneate, apex acuminate or acute, margin entire, slightly recurved when dry, midrib sunken adaxially, prominent abaxially, secondary veins 8–10 pairs, prominent on both surfaces, intersecondary veins distinct adaxially, intramarginal veins 1 (rarely 2, faintly visible), 1–2 mm apart from margin; petiole (0.4–) 0.8–1 cm long, concave adaxially, rounded abaxially, grayish green to yellowish brown, glabrous. Inflorescences terminal, racemose, 3- to 5-flowered, rarely solitary, peduncle 0.8–1.4 cm long, rachis and lateral branches terete or occasionally slightly compressed; bracteoles caducous, not seen.

Young twigs terete, yellowish brown to grayish brown, glabrous, old twigs grayish brown to very pale creamy brown, glabrous, internode 2–13 cm long.

V 750 [ster.] (FU!, VNM, the herbarium of Hon Ba Nature Reserve).</p> <p>Distribution:— Vietnam (so far only known from the type locality, Mt. Hon Ba).</p> <p>Habitat and Ecology:— Hill evergreen forest, at 890–920 m elevation.</p> <p>Phenology:— Flowering specimens collected in February.</p> <p>Etymology:— This species is named after Dr. Alexandre Emile Jean Yersin (1863–1943), a Swiss-French, for his contributions to the exploration of the Hon Ba mountain.</p> <p>Vernacular name:— Trâm yersin.</p> <p>Preliminary conservation assessment:— Endangered (EN). According to our observations in the field in Mt. Hon Ba and its adjacent areas (six times, from lowland to the summit of Mt. Hon Ba (ca. 1560 m elev.) in 2013–2017), Syzygium yersinii is endemic to Mt. Hon Ba and known only from the narrow range of Mt. Hon Ba, around 900 m elevation. We estimate the number of mature individuals to be fewer than 150, suggesting the situation is qualified as EN according to IUCN Red List criteria D (IUCN 2012). The forest in Hon Ba Nature Reserve is currently well protected from anthropogenic activities and therefore the population is seemingly stable.</p> <p>Note:— Lee et al. (2014: 398) identified this species as Syzygium formosum (Wallich 1831: 108) Mason (1851: 554) but S. yersinii is easily distinguished from S. formosum by its opposite leaves (vs. usually whorled in S. formosum) and terminal inflorescences (vs. in the axils of fallen leaves). The leaf texture and venation when dry is very similar to S. grande (Wight 1841: 17) Walpers (1843: 180), but differs from S. grande in its small habit (4 m tall vs. usually more than 20 m tall), subsessile leaves (vs. petiolate in S. grande) and more or less slightly cordate leaf base (vs. cuneate).</p> </div>	https://treatment.plazi.org/id/039D87D0FF9E8D18FF45CF88DED3F9DE	Public Domain	No known copyright restrictions apply.
