7. Lychnocephalus sellovii (Schultz-Bipontinus) Loeuille, Semir & Pirani (2019: 55) .

Lychnophora sellovii Schultz Bipontinus (1863: 372) .

Type:— BRAZIL. Minas Gerais: Serra do Vento , 1818, F. Sello (w) 996 (holotype: B †; lectotype: P! [P00683127] designated by Loeuille et al. (2019: 55)) ( Fig.6 E–F View FIGURE 6 , Fig.7 I–P View FIGURE 7 ).

Lychnophora saxosa Krascheninnikov (1922: 160) . Type:— BRAZIL. Minas Gerais: in saxosis Serra da Lapa , December 1824, L. Riedel 1126 (holotype: LE!; isotypes: LE! [2 specimens]).

Treelet, rarely shrubs, candelabriform, 0.5–1.2 m tall; poorly branched. Stems 1.7–2.4 cm diam., robust, dirty white, densely lanate, glabrescent, surface tessellate. Leaves sessile, weakly imbricate; leaf sheath amplexicaul, 0.9–2.5 × 1.1–2.2 cm, dirty white, abaxial surface densely lanate, adaxial surface glabrous, except by tuft of trichomes; blade narrow lanceolate or linear, 4.5–12.8 × 0.5–1.3–(2.8) cm, discolorous, mixed venation pattern parallelodromouscladrodomous, primary veins prominent abaxially, secondary veins covered by indumentum, abaxial surface dirty white, lanate, adaxial surface dark-green, lanulose, glabrescent, apex acute, base attenuate. Third-order syncephalium 2.1–4.1 cm tall, 3–4.6 cm diam., composed of 4–6 second-order syncephalia, spherical, solitary, terminal, covered by lanate indumentum, penduculate, peduncle 2.7–9 cm long; tertiary bracts 2.5–3.5 × 0.8–1.1 cm, lanceolate to linear; secondary bracts 1.2–1.6 × 0.4–0.7 cm, lanceolate to deltoid. Capitula 35–100, subinvolucral bracts 0.9–1.1 × 0.4–0.5 cm, deltoid; involucre campanulate, 1–1.1cm tall × 0.5–0.8 cm diam.; phyllaries 3-seriate, outer series shorter than inner series, lanceolate, apex acute, rarely obtuse, glabrous, margin entire, outer phyllaries 8–10 × 1–2 mm, inner phyllaries 10–11 × 1–2.2 mm; receptacle areolate. Florets 7–12 per capitulum; corolla deeply 5–lobed, purple, 1.3–1.6 cm long, corolla tube 10–13 × 0.5–1 mm, corolla lobes 3–5 × 0.5–1 mm, glabrous; anthers 5–6 × 0.3–0.5 mm, purple; style shaft 1.1–1.8 cm long, purple, glabrous throughout except for pubescent upper 1.5–1.8 mm beneath style arms, style arms 1.5–3 mm long. Cypselae cylindrical, 2.8–4 × 1–1.2 mm, brown; pappus setae biseriate, stramineous, outer series 1.1–1.3 mm long, apex erose, inner series 8–9 mm long.

Distribuition and habitat:— Brazil (Minas Gerais, Diamantina Plateau and Serra do Cipó). Campo rupestre, occurring in campo limpo phytophysiognomy at elevations between 1,060 and 1,420 m ( Fig. 8 View FIGURE 8 ).

Phenology:— Found with florets and fruits between the months of April and July.

Etymology:— The specific epithet honors Friedrich Sello(w) (1789–1831), a German naturalist who carried out expeditions in Brazil between 1814 and 1831 ( Vasconcelos & Pacheco 2012). The spelling of this specific epithet is “ sellovii ” and not “ sellowii ”, because Schultz-Bipontinus made an implicit Latinization of the surname when describing the species (ICN, Art. 60.9; Turland et al. 2018), thus this spelling should be preserved over “sellowii”.

Conservation status:— According to the GeoCat analyses, L. sellovii is classified as Endangered (EOO = 4.686, 792 km 2; AOO = 76.000 km 2) according to criteria B2ab(i,ii,ii,iv) ( Fernandez et al. 2020). Individuals of L. sellovii were registered within the limits of six Protection Areas: Environmental Protection Area (EPA) Barão and Capivara, EPA Águas Vertentes, EPA Morro da Pedreira, EPA Serra Talhada, Natural Monument (NM) of Lageado and Serra do Raio, National Park (NP) of Serra do Cipó. Despite presenting a larger area of distribution than most species, the campos rupestres where L. sellovii occurs are considered threatened due to activities that include agriculture, mining companies and human population expansion ( Costa et al. 2008)

Taxonomic notes:— This species is diagnosed by the combination of poorly branched candelabriform treelets, leaves with parallelodromous-cladrodomous venation pattern and heads with 7–12 florets. It is similar to L. canus , L. cipoensis and L. jolyanus due to the leaves with parallelodromous-cladodromous venation pattern. Further information is presented in the previous discussion. L. sellovii and L. tomentosus are the only species of Lychnocephalus that are not endemic to Serra do Cipó, both having a wider distribution along the Espinhaço Range ( Fig. 8 View FIGURE 8 ).
