Bark thin, exfoliating (fide type specimen), bark of old branches striate. Indumentum of golden shaggy trichomes, present on young branches, adaxial surface of the leaves along the midvein, bracts, bracteoles, flower buds, hypanthium, calyx lobes and petals. Young branches terete. Leaves with petioles 1–3 × 0.3–0.5 cm, canaliculate, glabrous; blades 9–11 × 3.5–4 cm, chartaceous, oblong, glabrous on both sides; base attenuate; apex cuspidate; venation brochidodromous, midvein raised on both sides, secondary veins 23–27 at each side, leaving the midvein at angles 65°–75°, raised on both sides, marginal vein ca. 1 mm from the margin; pellucid gland dots ca. 0.1 mm diam., 1–2 dots per mm². Inflorescences glomerate, ramiflorous, with 4–6 flowers; bracts 4, 2–3 × 1–1,5 mm, elliptic; bracteoles 2, 6–8 × 3–4 mm, ovate or elliptic, ciliate, persistent. Flower buds obovate, 7–12 × 8–10 mm, sessile, densely tomentose; hypanthium extended above the ovary, 4– 3 mm long, not constricted above the ovary, tearing during anthesis, deciduous; calyx lobes 4, 1–2 × 1–1,5 mm, partially fused, tearing irregularly at anthesis, pilose on both sides; petals 4, 5–8 × 2–5 mm; stamens with filaments 5–7 mm long after anthesis, anthers 0.4–0.7 × 0.3–0.4 mm, oblong or elliptic, rimose, connective eglandular, glabrous; style 7–12 mm long after anthesis, glabrous, stigma punctiform; ovary 2-locular, 3 ovules per locule. Fruits not seen.</p><p>Phenology:— Siphoneugena itatiaiensis was collected flowering in July.</p><p>Etymology:—The specific epithet refers to the place of collection, the municipality of Itatiaia.</p><p>Distribution and habitat:— Siphoneugena itatiaiensis is known from Dense Ombrophilous Forest in the Itatiaia National Park, in the municipality of Itatiaia, Rio de Janeiro, Brazil (Figs. 3, 4).</p><p>Conservation status:— Siphoneugena itatiaiensis is known from only a single collection with two specimens (RB and BHCB), from the municipality of Itatiaia. Currently, given the lack of sufficient information to make an assessment, directly or indirectly, of the risk of extinction based on its distribution and/or population status, this species can be considered as Data Deficient (DD; IUCN 2019) .</p><p>Comments:—Following the new classification of Pliniinae proposed by Stadnik (2020), the new species belongs to the genus Siphoneugena, characterized by a foliar blade with prominent primary ribs on the adaxial surface, glomeruliform inflorescences (Fig. 1 B), expansion and rupture of the hypanthium during anthesis, deciduous calyx lobes partially fused in the bud, and ovaries with 3–5 ovules per locule.</p></div>	https://treatment.plazi.org/id/987387E61D56692515DE95FCDA82F84F	Public Domain	No known copyright restrictions apply.

However, Berg included in the synonymy a previously published species, Eugenia edulis Vellozo (1829: 208, = Plinia edulis (Vell.) Sobral, 1985: 2), making M. plicatocostata an illegitimate name (Arts. 52 and 53 of the International Code for Nomenclature (ICN; Turland et al. 2018). Later, Glaziou (1908) made the combination Eugenia plicatocostata, also an illegitimate name due to the existence of an earlier homonym. Amshoff (1950) proposed the new combination Plinia plicatocostata, erroneously considered as illegitimate by Sobral (1985), who in turn proposed the illegitimate name Plinia anonyma (Art. 52 of the ICN; Turland et al. 2018). We here designate the P specimen (barcode P05228948) as the lectotype of Myrciaria plicatocostata because it is well preserved, fertile and displays the morphological characteristics described in the protologue Berg, O. (1857–1859) Myrtaceae . In: Martius, C.F.P. (ed.) Flora brasiliensis . Frid. Fleischer, Monachii, v. 14, p. 1, 656 p.</p><p>Paramitranthes sulcata was described by Burret (1941) and later transferred by Kausel (1966) to Siphoneugena, under the new combination Siphoneugena sulcata . This species, however, was excluded from Siphoneugena by Proença (1990: 268) in her revision of the genus, based on its foliar blades with adaxially sulcate midvein (while Siphoneugena has the “midvein somewhat raised or rarely flush with the upper surface, never sunken”, Proença 1990: 244). When discussing Siphoneugena sulcata, this author already suggested a relationship of this species to Plinia, (Proença 1990: 268) .</p><p>Based on the analysis of the protologues and type specimens of Paramitranthes sulcata and Myrciaria plicatocostata, we observed that both species are characterized by lanceolate and bullate leaf blades, with base cuneate or attenuate, apex acute or attenuate, midvein and lateral veins heavily grooved on the adaxial surface and prominent on the abaxial surface, and inflorescences in axillary glomerules with sessile flowers. Therefore, based on the congruence of similar vegetative and reproductive diagnostic characters, we here consider Myrciaria plicatocostata and Paramitranthes sulcata as conspecific; since P. sulcata is a legitimate and available name, it must supersede Plinia anonyma and be taken as the basionym for the new combination proposed here.</p></div>	https://treatment.plazi.org/id/987387E61D53692215DE93DADA6CFE49	Public Domain	No known copyright restrictions apply.
