Upright herbs or shrubs up to 2 m tall. Stem puberulous. Petiole 1.0– 2.5 cm long, puberulous; blade obovate to narrowly obovate, 12–20 (–25) × 3.8–6.0 (–11.0) cm, glabrous above, puberulous beneath, base attenuated, symmetric, apex acute, margin subentire to slightly crenate, with 1 or 2 intramarginal hydathodes per centimeter, secondary veins 10 to 14 per side, intramarginal vein present. Peduncle 3.5–9.5 cm long, glabrous to sparsely puberulous, ebracteolate. Hypanthium obconic, 8–9 × 5–6 mm, puberulous. Calyx lobes narrowly to very narrowly ovate, 9–16 × 2–4 mm, ascending, puberulous, basally spaced by sinuses 1 mm wide, margin entire, with 2 to 4 marginal teeth per side, apex rounded to acute. Corolla uniformly green, finely puberulous; tube 6.0– 6.7 cm long, ca. 5 mm basal and mid-level diameter, not inflated; lobes falcate, oblong-triangular, apex acuminate, dorsal lobes 20–25 × 4–5 mm, lateral lobes 15–18 × 3–4 mm, ventral lobe 10–12 × 4–5 mm. Synandrium 6.5–8.6 cm long, exserted up to 1.2 cm; filament tube 6.0– 7.7 cm long, glabrescent; anther tube 5–9 mm long, glabrous, ventral anthers barbate, with an apical tuft of trichomes up to 2 mm long. Berries globose, 1.0– 1.2 cm diameter, crowned by the persistent calyx lobes.  
 Phenology: — Burmeistera hippobromoides sets flowers and fruits in February, July and December.   
 Distribution, ecology and conservation status: — Burmeistera hippobromoides is endemic to the western slopes of the Colombian Western Cordillera, in the department of Valle del Cauca. The species occurs in rain forests at elevations between 400 and 900 m. Following the IUCN´s (2022) criteria [B1(EOO) and B2(AOO), conditions (a) and (b), and C2(a)(i)], it qualifies as Critically Endangered, due to its limited range of distribution, its low number of individuals, and the severe destruction of its habitat.   
 Notes: — Burmeistera hippobromoides is easily recognizable by its corolla tube not inflated, narrow and straight, 8.6–9.2 cm long, 2 to 3 times longer than in any other species of the genus.
