Agarista coriifolia var. coriifolia J. D. Hook. ex Nied. var. coriifolia Bot. Jahrb. Syst.

1.1. Agarista coriifolia (Thunb.) J.D. Hook. ex Nied. var. coriifolia Bot. Jahrb. Syst. 11: 236. Fig. 2 a-c Shrub 0.5–1 m tall; branches pubescent; non-glandular trichomes on branches, leaves and calyx; glandular trichomes absent. Leaves with reticulodromous venation, petiolate, petiole robust, 1.5–4.5 × 0.5–1 mm; leaf blades coriaceous, elliptic to ovate, 1.1–3.9 × 0.6–2 cm, apex rounded to obtuse, mucronate, base cordate, margin revolute, entire to repand, apical gland conical-elongated, adaxial surface glabrous to sparsely pubescent on the midvein, abaxial surface glabrous to sparsely pubescent on the midvein, conspicuous and darkened foveolate glands associated with secondary veins. Inflorescence terminal panicle, peduncle ca. 1 cm, rachis 3.3–6 cm long, pubescent; bracts deltoid and bracteoles filiform. Pedicel 3.8– 5.5 mm long; calyx lobes 1.6× 1.4 mm, pubescent; corolla 5–5.5 × 3–4 mm, pink, urceolate, sparsely pubescent at the apex; style ca. 5 mm long, glabrous; 10 stamens with filaments 3.3–4 mm long, pubescent, geniculate below the anther, anthers 1.4–1.6 mm long. Fruits not observed. Examined material: Tiradentes, Serra de São José, trilha do Mangue trail, 21°11’05”S, 44°19’73”W, 25. V.2015, fl., MTR Costa et al. 316 (HUFSJ). Agarista coriifolia var. coriifolia can be found only in campos rupestres in the states of Bahia, Goiás, Minas Gerais, and São Paulo. In the region studied by us, the species blooms and bears fruit between May and September. Among the species occurring in the region, Agarista coriifolia var. coriifolia bears a strong resemblance, primarily, to both A. pulchella var. cordifolia and A. subrotunda. However, it can be distinguished from A. pulchella var. cordifolia by the absence of foveolate glands associated with secondary veins. The differentiation between A. coriifolia var. coriifolia and A. subrotunda is even more straightforward, given that A. coriifolia var. coriifolia exhibits leaves with the abaxial surface either glabrous or pubescent only on the midvein, whereas A. subrotunda possesses leaves with a densely tomentose abaxial surface.
