Stems light-brown, not lenticellate, slightly fissured and rough, rounded, young shoots pubescent, soon glabrous. Petiole 3.0–11.5(–14.0) mm long, grooved, tomentose. Leaf blade coriaceous, (2.5–)7.0–20.5 × 3.5–6.5 cm , elliptic, narrow-elliptic, oblanceolate or narrow-oblanceolate, apex shortly acuminate, acute, rounded, emarginate or mucronate, base cuneate or acute, adaxial surface glabrescent or glabrous, but pubescent on midrib and secondaries, abaxial surface pubescent, venation eucaptodromous, midrib sunken on the adaxial surface, raised on the abaxial surface, secondaries 10–23 pairs, straight and arcuate near the margin, parallel, slightly sunken on the adaxial surface, raised on the abaxial surface, without intramarginal veins, tertiaries inconspicuous on the adaxial surface, raised on the abaxial surface. Inflorescences axillary or ramiflorous, 3–7-flowered. Pedicel 6.0–18.0 mm long, tomentose. Flowers purple in vivo ; sepals ca. 2.5 mm long, elliptic, ovate or oblong, apex acute, margin entire, abaxial surface hispid-tomentose or indument restricted to the base, adaxial surface glabrous, without a broad glabrous marginal stripe; corolla glabrous or indument restricted to the base on the abaxial surface, ca. 4.0 mm long, tube ca. 1.5 mm long, lobes 2.3–3.7 mm long, oblong, apex rounded; filaments 1.8–3.1 mm long, glabrous, anthers 0.8–1.6 mm long, glabrous; ovary ca. 2.0 mm long, ovoid, style ca. 1.5 mm long, glabrous, stigma simple. Fruit ripening yellowish-orange, 1.4–2.2 × 0.8–1.5 cm , ellipsoid, tomentose, calyx and style persistent. Seeds not available. Selected material: — BRAZIL .

Collected with flowers in September, October and November, with a single record in March ( Hatschbach 18822), with immature fruits in December, January and March and ripening fruits in June and August. It can be recognized by the geoxylic habit with a subterranean caulinar system and only shoot tips emerging above the ground, the leaves densely clustered at the stem apex, the stem rough due to dense leaf scars, and flowers with purple corolla, white stamens and greenish gynoecium. Conservation Status: —This species was listed as “Least concern” ( LC ) by CNCFlora (2018). In Paraná P. brevipes is irregularly distributed on small patches of Cerrado, and most of the individuals are in protected areas. The main problem to its conservation is the loss of habitat to agriculture or forest plantations, leading to small, isolated populations.
