Anthurium brigadeiroense Nadruz, Hammes & Temponi View in CoL in Hammes et al. (2020: 293-297) ( Fig. 2D–E View FIGURE 2 , 6E–H View FIGURE 6 ).

Terrestrial. Stem erect. Cataphylls and prophylls brown, completely marcescent to marcescent with an entire apex. Petiole 6.5–49.5 cm long., green to green with vinaceous dots from base to middle, abaxially acute to obtuse, adaxially flat to sulcate with obtuse angles, geniculum 0.2–0.6 cm long. Leaf-blade 14.5–47.0 × 2.0– 11.5 cm, green, slightly discolorous, erect to the petiole, coriaceous, linear, oblong to rarely elliptic, with a flat surface, acute to apiculate at the apex, acute at the base, truncate, obtuse, slightly cordate when juvenile, glandular punctuations absent. Midrib green on both sides, acute to obtuse throughout its length on the upper surfaces (acute at least in the apical portion), acute on the lower surfaces; primary lateral veins 9–14 on both sides; secondary and tertiary veins reticulate, basal vein (1)–(0), collective veins 0.2–1.8 cm distant from the margin. Inflorescence. Peduncle 4.0–34.0 cm long., vinaceous to green with vinaceous dots, terete to 1-ribbed. Spathe 3.0–7.5 × 1.0– 1.5 cm, green with vinaceous shading, erect to patent, decurrency green. Spadix 2.8–8.6 × 0.4–1.0 cm, homogeneous, slightly green with vinaceous dots to brown, cylindrical, sessile or shortly stipitate; stipe up to 0.4 cm long., bisexual flowers, pollen grains yellow, main spiral with 4–5 flowers; alternate spiral with 6–7 flowers, green berries, 2 seeds.

Distribution: — Anthurium brigadeiroense is endemic to Brazil, occurring only in Minas Gerais, more specifically endemic to the Serra do Brigadeiro State Park, since it was recently described ( Hammes et al. 2020, Flora do Brasil 2020). It was found at the Pedra do Pato trail (central PESB), Lage de Ouro, Matipó, and Pico do Boné (northern PESB) trails.

Ecology and phenology: —Found with flowers and young berries in February and July. Occurs in the Upper Montane Seasonal Forest areas of the PESB, mostly in small populations (3–4 individuals) in degraded areas, and larger populations (10 individuals) in shaded forest sites, at elevations from 1260 to 1650 m.

Taxonomic notes: —Differs from other Anthurium species found in the PESB species by its usually oblong leaf blade and green berries.
