Terrestrial herbs or shrubs up to 1 m tall, occasionally scandent to epiphytic. Stem glabrous. Petiole 0.6–1.5 (–3.5) cm long, glabrous; blade ovate to elliptic, 5–8(–14) × 2–4 cm, glabrous above and beneath, base cuneate, slightly asymmetric, apex acute to acuminate, acumen up to 1.5 cm long, margin slightly toothed, hydathodes 10 to 15 per side, marginal or extramarginal, secondary veins 9 to 12 per side, higher order venation loosely reticulate, intramarginal vein present, discontinuous. Peduncle 6.5–8.0 cm long, glabrous, ebracteolate. Hypanthium obconic, 5–7 × 4–5 mm, glabrous. Calyx lobes linear, 13–16(–20) × 1–2 mm, ascending or sometimes patent, basally spaced by sinuses up to 2 mm wide, margin entire to slightly toothed and then with two or three teeth per side, apex acute. Corolla pale pinkish to purple suffused with green, glabrous; tube 1.1–1.6 cm long, 2–3 mm diameter at its mid-level, slightly inflated proximally and distally; lobes narrowly ovate, falcate, curled back at late anthesis, apex acute; dorsal lobes 11–15 × 2–4 mm, lateral lobes 7–9 × 4–6 mm, ventral lobe 6–8 × 1.5–2.5 mm. Synandrium 2.5‒3.6 cm long, exserted up to 1.8 cm; filament tube 2–3 cm long, puberulous; anther tube 5–6 mm long, puberulous to glabrescent, ventral anthers ebarbate throughout. Berries pyriform, 1.0–2.5 × 1.2–1.4 cm, spongy, not inflated, pink, glabrous, crowned by the persistent but not accrescent calyx lobes.

Phenology: — Burmeistera serraniaguae sets flowers and fruits throughout most of the year.

Distribution, ecology and conservation status: — Burmeistera serraniaguae is restricted to cloud sub-Andean and Andean forests of the Western and Central cordilleras of Colombia, in the departments of Antioquia, Cauca, Chocó, Risaralda and Valle del Cauca, at elevations between 890 and 2700 m. Following the IUCN (2022) Guidelines, this species qualifies for the Near Threatened (NT) category.

Notes: — Burmeistera serraniaguae is similar to B. succulenta , from which it differs by the hypanthium 5–7 × 4–5 mm; the calyx lobes 1–2 mm wide; the corolla with tube 2–3 mm diam. at its mid-level, dorsal lobes 11–15 × 2–4 mm, lateral lobes 7–9 × 4–6 mm, and ventral lobe 6–8 × 1.5–2.5 mm; and the synandrium exserted up to 1.8 cm, with anther tube 5–6 mm long (versus the hypanthium 8–14 × 5–9 mm; the calyx lobes 2–3(–4) mm wide; the corolla with tube 4–5 mm in diameter at its mid-level, dorsal lobes 15–25 × 3–5 mm, lateral lobes 14–20 × 3–5 mm, and ventral lobe 12–16 × 2.8–3.0 mm; and the synandrium exserted up to 2.4 cm, with anther tube 10–12 mm long in B. succulenta ).
