Leaves all alternate, subsessile, chartaceous, laminas (0.6–)0.8–1 × 0.08–0.1 cm, linear, apex acute, margins revolute, base acute, densely covered by small glandular trichomes on both sides. Racemes congested to shortly elongated 1.2–1.9 × 0.8–1 cm, up to 3.3 cm long after capsules have fallen; bracts 1.2 × 0.5 mm, lanceolate, apex acute, not ciliate, without yellowish glands, deciduous before anthesis, ca 2 times as long as the bracteoles; bracteoles elliptic, not ciliate; pedicel 1.5 mm long, glabrous. Flowers yellow, cream or whitish, 5.4–5.5 mm long (without pedicel); outer sepals not ciliate, with yellow glands; lower outer sepals 1.5 × 0.6 mm, elliptic to ovate, apex obtuse; upper outer sepals 1.4–1.5 × 0.6–0.7 mm, elliptic, apex rounded or slightly retuse; inner sepals (wings) 4.5 × 2.2 mm, elliptic, apex acute, margins not ciliate, longer than the mature fruits, without yellow glands; lateral petals 4.1 × 1 mm; keel ca 3.5 mm long, cristate, with yellow glands around the dorsal central vein, deciduous on mature fruits; crest 4–6-lobed; central lobes often bi-lobed to apex, style 1.5 mm long, erect, terminated by an oblique cymbiform pre-stigmatic cavity, posterior extremity with a conspicuously crested appendage with abundant trichomes and an anterior globose stigma. Capsules 3.5 × 1.7 mm, subovate, bearing a double line of orange glands close to the central nervure, style deciduous in fruit; seeds ca 2.5 × 1–1.1 mm, obclavate, pubescent, trichomes 0.1–0.2 mm long, without a ring of trichomes at the base of the seed, with two caruncular appendages 1.5 × 0.2–0.3 mm reaching approximately ½ of the seed length.</p> <p>Distribution, habitat, and phenology</p> <p>Polygala bringelii sp. nov. is endemic to the Jalapão region, Tocantins State, occurring in open natural grasslands with scattered shrubs (campo sujo and campo cerrado), occasionally near rocky outcrops, on sandy dry soils at altitudes of 350 to 550 meters in the municipalities of Mateiros and Ponte Alta do Tocantins (Fig. 2). Found fertile in January and from May to August.</p> <p>Preliminary conservation status</p> <p>The estimated Area of Occupancy, with just 36 km ², is low; the estimated Extent of Occurrence is 1469.542 km ². The species is currently known from ten collections, with most located inside the protected area of the Parque Estadual do Jalapão. Nominally protected, these areas are still subjected to uncontrolled anthropic fires, though recently diminished in number due to a new fire management program (Schmidt e t al. 2018). Nearby areas, mostly in western Bahia State, have already been converted to agricultural use (Borges &amp; Antar 2016), which is expanding towards the Jalapão with governmental incentives (Antar et al. 2018; Barbosa-Silva &amp; Antar 2020). Although still regarded as data deficient, due to the precarious state of conservation of its suitable habitats, the species should be assessed as Endangered EN B1ab(i,ii,iii)+2ab(i,ii,iii) (IUCN 2012).</p> <p>Notes</p> <p>Morphologically, Polygala bringelii sp. nov. is most closely related to P. trichosperma, with both species sharing the oblong-elliptic capsules with yellow glands along the mid-vein and linear leaves. However, P. bringelii sp. nov. differs from P. trichorperma in the characters discussed in the diagnosis. Also, this new species is seemingly similar to Polygala tocantinensis sp. nov. (the other new species here described), both of them share similar sepals and yellowish flowers, differing mainly by the seed indument, with a ring of long trichomes at the seed base (vs seed without a ring of trichomes at the base in P. bringelii sp. nov.) and the keel crest in P. tocantinensis sp. nov. is much more developed (ca twice the size) than in P. bringelii sp. nov.</p></div> 	http://treatment.plazi.org/id/03D2878DC401605AFE71CDC19B4EFDC6	Public Domain	No known copyright restrictions apply.

Although considered for now endemic to Tocantins State, Polygala tocantinensis sp. nov. may also occur in the municipality of Formosa do Rio Preto, Bahia State, as the type collection was made at the division between the two states. Future collecting efforts in a similar physiognomy in Bahia State may prove successful for finding new populations of P. tocantinensis sp. nov.</p> <p>Preliminary conservation status</p> <p>The estimated Area of Occupancy, with just 16 km ², is low; the estimated Extent of Occurrence is 1831.048 km ². This species is known from only four collections in four different localities, with two of these located inside the protected areas of the Parque Estadual do Jalapão and Estação Ecológica Serra Geral do Tocantins. As is the case with Polygala bringelii sp. nov., these areas are still subjected to uncontrolled anthropogenic fires and are been rapidly converted to agricultural use. Although still regarded as data deficient, due to the precarious state of conservation of its suitable habitats, the species should be assessed as Endangered EN B1ab(i,ii,iii)+2ab(i,ii,iii) (IUCN 2012).</p> <p>Notes</p> <p>Morphologically, Polygala tocantinensis sp. nov. is most closely related to P. trichosperma, with both species sharing the oblong-elliptic capsules with yellow or orange glands along the mid vein and linear leaves.
