description: 17. Burmeistera fimbriata Lammers, Novon 12: 209. 2002.   
Type:— COLOMBIA. Huila: Vertiente oeste de la Cordillera Oriental, 29 km de la carretera que de Guadalupe conduce a Florencia, ca. 1.5 km del límite entre Caquetá y Huila, 01°55´N, 75°43´W, 2250‒2350 m, 22 Mar 1986 (fl, fr), B. Stein 3706 (holotype: MO! [MO3330183]; isotype: COL! [COL000062129]). Figs. 9, 10E –G.  
Herbs up to 1 m tall. Stem denselly hirtellous. Petiole 2–4 cm long, hirtellous; blade elliptic, 10–23 × 3.0– 8.8 cm, scarcely hirtellous above, densely hirtellous especially along the veins beneath, base attenuate, apex acuminate to cuspidate, margin fimbriate, fimbriae hirtellous, 4–8 per cm, up to three sizes intermixed, the smallest 0.8–1.5 mm long, up to 6 mm long, hydathodes extramarginal (at the fimbriae tips), secondary veins 10 to 12 per side, intramarginal vein lacking. Peduncle 7.0– 12.5 cm long, puberulous, hirtellous, with two linear bracteoles near its base, each 8–9 × 0.5–0.6 mm. Hypanthium obconic, 15–17 × 6–8 mm, hirtellous. Calyx lobes lanceolate, 15–30 × 5–6 mm, nearly 2 times the length of the hypanthium and as long as the corolla tube, basally contiguous and connate by 1–2 mm, patent to ascending, hirtellous, margin with fimbriae and 6 to 10 teeth per side, apex acuminate. Corolla green, glabrous except for the commissure of the dorsal lobes that is scarcely puberulous; tube 2–3 cm long × 4.5–5.0 mm diameter at its mid-level, inflated proximally and distally; lobes oblong-triangular, slightly falcate, apex acuminate, dorsal lobes 11–13 × 3‒5 mm, lateral lobes 10–12 × 5–6 mm, ventral lobe 10–12 × 4.5–5.5 mm. Synandrium 4.2–4.6 cm long, exserted up to 9 mm; filament tube suberect, 3.4–3.6 cm long; anther tube 8–10 mm long, glabrous, ventral anthers barbate, with an apical tuft of white to yellowish trichomes up to 1.5 mm long. Berries narrowly obconic, ca. 1.0 × 0.3 cm.  
 Phenology: —The species has been collected with flowers and fruits in March.   
 Distribution, ecology and conservation status: — Burmeistera fimbriata is known only from the type specimen, collected at the western slopes of the Eastern Cordillera in the department of Huila, at elevations between 2250 and 2350 m. Additionally, a photographic record lacking herbarium specimen was taken in Cundinamarca by D.A. Fonseca (Department of Biology, National University of Colombia). Following the IUCN´s (2022) criteria [B1(EOO) and B2(AOO), conditions (a) and (b), and C2(a)(i)], B. fimbriata qualifies as Critically Endangered.   
 Notes: — Burmeistera fimbriata is similar to B. venezuelensis, especially by the dense indument and the bracteolate peduncle. The species clearly differs from its congeners by the densely hirtellous indumentum, the fimbriate margin of leaf and calyx lobes, and the bibracteolate peduncle.
