Twigs with erect simple light brown or yellowish trichomes +0.3–0.5 mm +, these falling with age and then becoming grey or brown and longitudinally striate; base of the twigs frequently with persisting triangular cataphylls to 1 × +0.3–0.4 mm +. Leaves with petioles 0.5–1.5 × +0.2–0.5 mm +, pilose as the twigs, adaxially applanate; blades ovate or elliptic, 14–35 × +8–12 mm +, 1.7–3 times longer than wide, when young covered with simple trichomes as the twigs on both sides, when adult with the trichomes absent or restricted to the midvein at the adaxial side and scattered along the surface at the abaxial side, discolorous when dry, dark green and occasionally shining adaxially, lighter and dull abaxially; base obtuse; apex acute or occasionally widely acuminate in +2–3 mm +; glandular dots evident and sometimes raised on both sides, 30 to 40/mm², of several sizes, the larger ones about +0.05 mm +in diameter, these more scattered than the smaller ones; midvein plane or finely sulcate adaxially and raised abaxially; lateral veins 6 to 10 at each side, leaving the midvein at angles 45–60°, moderately raised on both sides, occasionally the first or second vein extending along nearly all the extent of the blade and forming the marginal vein; marginal vein continuous, to +1 mm +from the margin, this sometimes with cilia to +0.2 mm +. Inflorescences with solitary flowers or more frequently two flowers, these axillary or arising from ramiflorous brachyblasts, on both cases the axis not visible; bracts widely ovate, to 0.3 × +0.2 mm +, pilose as the twigs, usually deciduous before anthesis; pedicels 4–4.5 × +0.2–0.3 mm +, with simple hispid trichomes to +0.2 mm +; bracteoles triangular, persisting after anthesis, 0.6–0.8 × +0.5 mm +, with trichomes to +0.3 mm +; flower buds elliptic, to 3 × +1.2 mm +, the hypanthium and the calyx lobes with scattered trichomes to +0.3 mm +; sepals four, markedly glandulose, adaxially glabrous, in two slightly unequal pairs, the inner one acute, to 0.8 × +0.6 mm +, the outer one elliptic or widely elliptic, to 1 × +0.7 mm +; petals oblong or oblong–ovate, glabrous or with scattered trichomes, 3.5–4 × +0.7–0.8 mm +; stamens 25 to 35, the filaments +3–3.5 mm +, the anthers elliptic, to 0.3 × +0.2 mm +, with one apical gland, this apparently sometimes deciduous; staminal ring to +1 mm +in diameter, with scattered trichomes; calyx tube to +0.5 mm +deep or absent; style glabrous, to +5 mm +, the stigma slightly capitate and papillose; ovary with two internally glabrous locules and 3 ovules per locule. Fruits ellipsoid, 7–15 × +5–8 mm +, black when ripe; seed one, ellipsoid, the testa easily detachable from the embryo and adherent to the endocarp; embryo with two plano-convex cotyledons and no visible hypocotyl. + + + + +FIGURE 1. + +Eugenia saxatilis + +.

Azevedo); lower left: São Francisco inselberg (photo L. de Paula). + + + + +Distribution, habitat and phenology:—This species is known from seasonal forests, belonging to the Atlantic Forest domain, on isolated granite and/or gneiss rock outcrops (“pães de açúcar”, “inselbergen” or “sugar loaves”) about +560 m +elev. in the eastern portion of the state of +Minas Gerais +; these outcrops have been considered as local hotspots of plant diversity ( + +de Paula +et al. +2020 + +). More specifically, + +E. saxatilis + +was found only on the so-called “thicket” or “scrub” vegetation +type +( +Rizzini 1997 +), which is a transition zone between the rock outcrop and the seasonal forests that border the inselberg. Flowers and fruits were collected in December and January. + + + + +Conservation:— + +Eugenia saxatilis + +is presently known from four collections; three recent georeferenced records at the São Francisco inselberg and one made in 1961 bearing only the information “between Teófilo Otoni and Nanuque”, two municipalities about +50 km +apart. These municipalities encompass together an area of +4,760 km +² ( +IBGE 2021 +), in which there are 999 plant records ( +INCT 2021 +), resulting in a very scarce sampling effort of 0.2 collection/km², if considered the minimal value proposed by +Campbell (1989) +of one collection/km² for tropical countries; considering this, the present evaluation may be altered significantly when this region becomes better botanically explored. The georeferenced specimens allow estimating via GeoCat (2020) an Extent of Occurrence (EOO; +IUCN 2012: 11 +) for this species of +0.005 km +², a very small area which would point to a Critically Endangered (CR) status (GeoCat 2020, +IUCN 2012 +). Furthermore, inselbergs are significantly threatened by mining, quarrying, invasion of exotic plants, altered and more frequent fire regimes, cattle and goat herding and changing in the surrounding land use mainly due to farming ( + +Porembski +et al. +2016 + +). Thus, the natural vegetation in these ecosystems faces increasing risks of extinction. Nevertheless, although the species have an apparently small area and occur in fragmented habitats ( +IUCN 2012: 17 +) there are no additional information regarding population decline or extreme populational fluctuations in order to adequately fulfill IUCN criteria ( +IUCN 2012 +), and consequently for now we score + +E. saxatilis + +as DD (Data Deficient; see +IUCN 2019: 78 +). + + + + +Affinities:—This species is morphologically close to + +Eugenia repanda + +, a species occurring from +Bolivia +to +Uruguay +( + +Govaerts +et al. +2021 + +); considering its reduced inflorescence structure it probably belongs to section + +Umbellatae +O. +Berg (1855 + +–1856: 204), according to the sectional classification proposed by + +Mazine +et al. +(2016: 231) + +. + + + +Etymology:—The epithet is derived from the Latin word for rock-dwelling, the typical habitat of the species. + + + +Paratypes +:— + +BRAZIL +. +Minas Gerais +: +Teófilo Otoni +, +fazenda de Cássio Adinny +, +17°51’23” S +, +41°15’44” W +, + +28 January 2014 + +, fl., + +L.A.F. de Paula +, +L.O.
