03917F1CA935FF8CFF0DCCF2FB32FB7C.taxon	diagnosis	Diagnosis: — Myrcia damaniensis is similar to Myrcia chytraculia (Linnaeus 1759: 1056) A. R. Lourenço & E. Lucas (in Lourenço et al. 2018: 74) var. americana (McVaugh 1963: 404) G. P. Burton & E. Lucas (in Burton et al. 2021: 1023). Nevertheless, it can be easily distinguished by the size of its leaves (<15 cm vs.> 15 cm), leaf blades, elliptic, widely elliptic or suborbicular (vs. elliptic-ovate) and leaves with nearly indiscernible or weakly evident secondary venation on both surfaces (vs. leaves with prominent venation on abaxial surface). The apex in both species can be acuminate but M. damaniensis can also have a caudate or cuspidate apex.	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

03917F1CA935FF8CFF0DCCF2FB32FB7C.taxon	distribution	Distribution, habitat and phenology: — This species has been found on the shores of Damani and Oiba lagoons and along the channels of the wetland, in areas of mixed swamp forest with abundant Campnosperma panamense (Fig. 2 A). One flowering specimen was collected in June, and fruiting specimens in September and October.	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

03917F1CA935FF8CFF0DCCF2FB32FB7C.taxon	conservation	Conservation: — Myrcia damaniensis has been found only in the Damani region, within the protected area Damani-Guariviara Wetlands of International Importance. Despite its protected status, the forests in the area are being cut down for subsistence agriculture and cattle ranching by an increasing population. This situation may reduce its small area of occupation (AOO) which is estimated just at 4 km ²; therefore, we consider that this species fits the category Endangered [EN B 2 ab (ii, iii, iv)] of the IUCN Red List and criteria (IUCN 2012).	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

03917F1CA935FF8CFF0DCCF2FB32FB7C.taxon	discussion	Discussion: — Myrcia damaniensis has the calyx lobes fused into a single structure that opens circularly through a calyptra. Based on this morphological characteristic, this species would belong in Myrcia sect. Calyptranthes (Swartz 1788: 79) A. R. Lourenço & E. Lucas, according to a recent phylogenetic study (Lucas et al. 2018: 3). Myrcia damaniensis is apparently related to Myrcia chytraculia var. americana. Both species have inflorescences alate, multiflorous and covered with a reddish pubescence. However, both species are distinguished by the characters listed in the diagnosis. With the description of Myrcia damaniensis, 34 species of Myrcia are recognized in Panama.	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

03917F1CA933FF81FF0DCD18FC2DF9CC.taxon	diagnosis	Diagnosis: — Eugenia tain is morphologically similar to Eugenia belloi Barrie (2005: 4) and to Eugenia skutchii C. V. Morton & Standley (in Standley 1937: 774). From E. belloi, E. tain can be distinguished by its leaves chartaceous and mainly obovate, although occasionally ovate or elliptic, (vs. leaves coriaceous and elliptic), generally shorter petioles, 6 – 11 mm (vs. petioles generally longer, 10 – 20 mm); hypanthium campanulate (vs. globose), sepals markedly inequal (vs. subequal). From E. skutchii, E. tain can be distinguished by its generally shorter petioles, 6 – 11 mm (vs. petioles generally longer, 10 – 20 mm), smaller leaf blades, 7.5 – 18 cm (vs. larger blades, 13 – 24 cm), and lateral veins 9 – 15 per side (vs. lateral veins 16 – 20 per side).	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

Leaves opposite, petiolate, the petioles 6 – 11 × 1 – 1.8 mm, canaliculate; blades mostly obovate, ocasionally ovate or elliptic 7.5 – 18 × 3.3 – 10.3 cm, chartaceous, bicolorous, the adaxial surface pubescent or glabrescent, bright green when fresh, light to dark brown, greenish or brown-reddish when dry, abaxial surface, ochre or green-grayish when fresh and ochre or brown-grayish when dry, glands inconspicuous but visible at 10 ×; apex caudate, acuminate to cuspidate; base acute; midvein adaxially slightly sulcate, abaxially prominent, convex, pubescent; lateral veins 9 – 15 per side, ascending from the midvein to a marginal vein equaling the lateral veins in prominence and slightly arched between ca. 1 – 2 mm from the margin, sometimes the marginal veins inconspicuous on the abaxial surface. Inflorescences racemose, solitary, occasionally paired, supra-axillary or subterminal, axes to 20 (- 25) mm, 1 – 6 flowers per inflorescence, peduncle 1.5 – 3.5 mm long or occasionally not visible; bracts persistent, pubescent on both surfaces, 0.7 – 1.5 × 0.5 – 1.3 mm, elliptic or subtriangular, apex acute; pedicels 5 – 11 mm long; bracteoles persistent, pubescent on both surfaces, 1.5 – 2 × 1.5 – 2 mm, subtriangular or ovate, apex acute or subobtuse.

03917F1CA933FF81FF0DCD18FC2DF9CC.taxon	distribution	Distribution, habitat and phenology: — This species is common in the Damani-Guariviara wetlands. It thrives in the mixed swamp forest with an abundance of Campnosperma panamense and is frequently seen along channels and lagoons. It had a density of 14 individuals (2 %) in one hectare of mixed swamp forest in the wetlands (López et al. in prep.). It has also been collected in Escudo de Veraguas Island where it was found on the coastal border and in the swamp forest (Fig. 2 B, 2 C). The species was also found in the wetland forest (on the side of a river) of Donoso, in Colón province, in an area of a large copper mining operation. Flowering specimens were collected in May, June, September and fruiting specimens in February, May, June, September and October. Conservation: — This species has been found in three locations, two of them within protected areas (Escudo de Veraguas Island Protected Landscape and Damani-Guariviara Wetlands of International Importance) and one (Donoso), which is part of a mining project that has caused great deforestation and loss of habitat. The two protected areas are not properly managed by personnel from the Ministry of Environment. Both areas are being seriously affected by unsustainable practices such as clear cutting for cattle ranching, rice cultivation, slash and burn agriculture (DamaniGuariviara), timber extraction, and uncontrolled tourism (Escudo de Veraguas). Due to the strong negative impact that its habitat is receiving, the Extension of Occurrence (EOO) of 1,699.530 km 2 and an Area of Occupation (AOO) of 20 km 2, we consider that Eugenia tain fits the category of Vulnerable (VU) [VU B 1 ab (i, ii, iii, iv) + 2 ab (i, ii, iii, iv)] of the IUCN Red List and criteria (IUCN 2012).	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

03917F1CA933FF81FF0DCD18FC2DF9CC.taxon	etymology	Etymology: — The epithet of this species refers to the common name given to it by the Ngäbe indigenous inhabitants of that region, “ Jabona tain ” (tain meaning red in the ngäbere language), an allusion to the reddish, ochraceous color of the underside of the leaves.	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.

03917F1CA933FF81FF0DCD18FC2DF9CC.taxon	discussion	Discussion: — Eugenia tain has a racemose inflorescence in which the ratio pedicel: internode is 2: 1. Based on this, according to the phylogenetic study by Mazine (2006), it must be included in Eugenia sect. Racemosae O. Berg (1856: 278). Eugenia tain is similar to Eugenia belloi and to Eugenia skutchii from Costa Rica. All three species have leaves uniformly covered with ochre appressed trichomes on the abaxial surface. However, they can be distinguished by the characters listed in the diagnosis and their different habitats. Eugenia tain grows at low elevations in coastal and swamp forests in the Caribbean, while E. belloi and E. skutchii grow in humid montane forests at elevations up to 1,800 m in the Pacific watershed. With the description of Eugenia tain, 39 species of Eugenia are now recognized in Panama.	en	Flores, Rodolfo, Holst, Bruce K., Ibáñez, Alicia (2022): Two new species of Myrtaceae from the western Caribbean forests of Panama.
