Eugenia funchiana Coutinho & M.Ibrahim sp. nov . , ( Figures 2 and 5 ) This species is similar to Eugenia dentata Niedenzu (1897: 82) , but differing from the latter by the undulate margin of the leaf; petiole 1–2 mm long; pedicels 13–15 mm long; and hypanthium not costate. Type:— BRAZIL . Bahia : Monte Santo. 10°27’00”S 39°20’00”W . 21 February 1974 . R.M. Harley 16431 ( holotype CEPEC!, isotype RB! MO, NY). Tree 4 m high; young twigs brownish, pilose, adult branch grayish–brown, glabrous. Leaf blades 16–24 × 8–13 mm , hyaline, membranaceous, ovate or lanceolate; apex acute; base cuneate; margin undulate, glabrous or pilose; glandular dots impressed, 0.05–0.1 mm diam., ca. 16 per square millimeter; venation brochidodromous; midvein sulcate in the proximal portion and impressed in the distal portion of the adaxial, prominent below, glabrescent; lateral veins 8–13, rarely curved, sub–erect, leaving the midvein at 35°–40°, glabrescent; marginal vein formed by secondary veins; petiole 1–2 × 0.2–0.3 mm , channeled, pubescent. Inflorescences axillary; 2–4 flowered, rachis absent at 0.9 mm ; pedicels 13–15 × 2–4 mm , glabrous; bracts ca. 3.5 mm , spatulate, apex acute, pilose, glandular dots present; bracteoles not seen; buds 4.9 × 2.7 mm ; calyx lobes four, 2.5–2.9 × 1.1–1.2 mm , ciliate, apex cuneate, glabrous, glandular dots present; petals four, 3.4–3.5 × 0.8–0.9 mm , spatulate or linear, undulate or ciliate, apex acute or rounded, glabrous, without glands; hypanthium 1.2–1.3 × 1.0– 1.2 mm , not costate, pubescent; staminal ring 2.8–3 mm diam., glabrous; stamens 60, 1.9–3.4 mm ; glabrous, anthers elliptic; style 3–3.3 mm , glabrous, stigma punctiform; bilocular, pluriovulate, glabrous. Fruit not seen. FIGURE 2. Eugenia funchiana Coutinho & M.Ibrahim. A . Habit. B . Detail of inflorescence (scale 1 cm). Etymology:— The species epithet is in honor of professor and researcher Ligia Silveira Funch, who has contributed significantly to our knowledge of the vegetation of the semiarid region of Bahia State . Phenology:— Flowers in February. Distribution and habitat:— This species was collected at 610 m elev. on a quartzite rock substrate in the municipality of Monte Santo, in the semiarid region of northern Bahia State . The climate there is tropical semiarid with an average annual precipitation of 750 mm and an average annual temperature of 26 °C ( Velloso et al . 2002 ). The predominant phytophysiognomy of this region is shrub caatinga, although the native vegetation is rapidly being substituted by plantations and pastureland. Morphological comments:— Eugenia funchiana is similar to Eugenia dentata Niedenzu in terms of the placement of their leaves on the branches, and spatulate petals. Although they share these characteristics, E . funchiana has oval or lanceolate leaves with undulate margins, visible veins on both faces, hypanthium not costate and pubescent. E. dentata , on the other hand, has oblong–lanceolate or oblong leaves, with repand–dentate margins, veins not visible on the adaxial surface, and the hypanthium is costate and glabrous. Conservation status :—The municipality of Monte Santo covers 3186 km ² (IBGE 2015) with 1047 collections of this species according to the Species link website ( CRIA 2015 ), generating an average of 0.3 collections/km². However, as the rarity of this species may be attributed to few collections, it seems more appropriate to adopt the IUCN category DD (deficient data; IUCN 2012 ).
