Perennial herb, erect, 20–80(–100) cm tall; stems pilose and occasionally covered with glandular-capitate hairs. Leaves with petioles 2–6.4 mm long, sparsely to densely pilose; leaf blade lanceolate, oblong-lanceolate to ovate-lanceolate, (1.5–)2.8–6.3 × 0.8–1.8(–2.6) cm, acute to rounded at the apex, rounded at the base, margin crenate to serrate, bullate, glabrous and sparsely pilose above, white tomentose beneath. Inflorescences in racemes 12–21 cm long, 4–10 verticillasters each, these 2–4(–6)-flowered, lowermost nodes 2.5–4.4 cm apart. Floral bract lanceolate to ovate-lanceolate, 2.8–8 × 1.5–3 mm, deciduous, acute to caudate at the apex, truncate at the base, margin entire, sparsely pilose and ciliated at the margin. Flowers with pedicels 3.6–5.8(–7.2) mm long, pilose and puberulent. Calyx (6.2–) 8.3–11 mm long, 3.8–6 mm wide at the throat, green and purple tinged, pilose, internally covered with tiny appressed hairs, the upper lip 7-veined and entire, lobes of the lips acute. Corolla magenta or purple and with white nectar guides on the lower lip, glabrous except for the upper lip which is sparsely pilose; corolla tube 7–15 mm long, 4.8–7.2 mm wide at the throat, ventricose, constrained toward the base and internally ornate with two papillae; upper lip 5.2–9.2 mm long, lower lip 10–16 × (5.8–) 9.2–12 mm, deflexed. Stamens 2, included; filament 2.4–4 mm long; connective 9.8–12 mm long, ornate at midportion with a short acute tooth; theca 1.7–3.2 mm long. Gynobasic horn 1–1.2 mm long; style 1.6–2.2 cm long, pilose at the apex, lower stigmatic branch acute. Mericarp ovoid, 2.5–2.9 × 1.8–2 mm, light brown and dark brown marbled, smooth and glabrous.

Distribution, habitat and phenology: Salvia dichlamys inhabits the Mexican states of Estado de México, Guerrero, Jalisco and Michoacán (fig. 4). It grows in oak and pine-oak forests, from (1167–) 1800– 2400 m. It shares habitat with Arctostaphylos pungens Kunth , Pinus oocarpa Schiede ex Schltdl. , Quercus castanea Née , Q. gentryi C.H.Mull , Q. magnoliifolia Née. It flowers and fructifies from the end of May to November.

Discussion: Klitgaard (2012) considers Salvia dichlamys to be conspecific with her concept of S. amarissima . The first belongs to section Fulgentes Epling (1939: 273) and the other to section Uricae Epling (1939: 174). Section Fulgentes differs because the lack of long glandular-capitate hairs throughout the stems, 7-veined upper calyx lip (vs. 5-veined), and red corollas (vs. blue corollas) though there are some populations of S. dichlamys and S. microphylla with purple ones. Furthermore, S. dichlamys has shorter petioles [(2–6.4 vs. (7–) 30–44 mm)], oblong-lanceolate to ovate-lanceolate leaves (vs. ovate-deltoid to ovate), less flowers per verticillaster [2–4(–6) vs. 6–10], usually bigger calyces [(6.2–)8.3–11 × 3.8–6 vs. 4.7–7 × 3–4 mm], longer corolla tube [7–15 vs. 5–6.5(–7.3) mm], longer lower corolla lip [(10–16 vs. 7–10(–11.3) mm)], longer filament (2.4–4 vs. 1.5–1.7 mm), longer connective [9.8–12 vs. (2.5–) 5–5.5 mm] and longer style [1.6–2.2 vs. (0.8–) 1.2–1.4 cm], and bigger mericarps [2.5–2.9 × 1.8–2 vs. (1.6–)2.1–2.2 × (0.5–) 1–1.1 mm]. Salvia dichlamys does not grow in Mesoamerican region (fig. 4).
