description: 26. Burmeistera killipii Gleason, Bull. Torrey Bot. Club 52: 99. 1925.   
 Type:— COLOMBIA. Cauca: La Gallera, Micay valley, 2200‒2500 m, 01 Jul 1922 (fl), E. Killip 7980 (holotype: NY! [NY00467994]; isotypes: GH! [GH00033085], PH! [PH 00010888], US! [US 00146944]). Figs. 14, 15F.   
Climbing herbs up to 1.2 m tall. Stem hispidous-strigose. Petiole 2–11 mm long, hispidous-strigose; blade broadly ovate, 2.0–4.6 × 1.7–3.5 cm, bullate, glabrous, usually strigose and with venation imprinted above, puberulous along venation beneath, base slightly cordate, apex obtuse or sometimes acute to acuminate, margin subentire, serrulate, with 1 or 2 marginal or extramarginal hydathodes per cm, secondary veins 4 to 6 per side, impressed above, prominent beneath, intramarginal vein lacking. Peduncle 2.3–5.0 cm long, glabrous to hispidous-strigose, ebracteolate. Hypanthium globose to campanulate, 4–7 × 4–5 mm, hispidous-strigose, usually warty. Calyx lobes narrowly ovate, 4–7 × 1.5–2.5 mm, strongly reflexed, glabrous, warty on both sides, margin subentire, apex acute to obtuse. Corolla green suffused with purple, glabrous, usually warty above and beneath; tube 1.2–1.8 cm long, 3–4 mm diameter at its mid- and distal portion, slightly inflated proximally; lobes ovate, slightly falcate, apex acuminate, dorsal lobes 11–15 × 5‒6 mm, lateral lobes 10–14 × 4–7 mm, ventral lobe 8–10 × 5–6 mm. Synandrium 4.2–5.0 cm long, exserted up to 3 cm; filament tube 3.8–4.5 cm long, glabrous, warty; anther tube 4–5 mm long, usually warty, glabrous, ventral anthers barbate during pre-anthesis, later ebarbate. Berries obovoid to oblate, 1.2–1.5 × 1.2–1.8 cm, glabrous, not inflated but spongy, white with purple calyx lobes.  
 Phenology: — Burmeistera killipii sets flowers and fruits from March to August.   
 Distribution, ecology and conservation status: — Burmeistera killipii is restricted to cloud forests of the Western Cordillera, in the the department of Cauca (Colombia), at elevations between 1320 and 3000 m. The hummingbird Eriocnemis mirabilis has been reported as a floral visitor of this species in the specimen Olives et al. (MDMOP-10). Following the IUCN´s (2022) criteria [B1(EOO) and B2(AOO), conditions (a) and (b), and C2(a)(i)], B. killipii qualifies as Critically Endangered.   
 Notes: — Burmeistera killipii is closely related to B. loejtnantii, from southern Colombia and Ecuador. The species differs by the hispidous-strigose indumentum of stems, petiole, peduncle, hypanthium and calyx lobes; the leaf blade bullate with margin subentire, not toothed, apex obtuse (rarely acute to acuminate), and 4 to 6 secondary veins per side; the peduncle 2.3–5.0 cm long; the calyx lobes strongly reflexed; the corolla warty above and beneath, with dorsal lobes 11–15 × 5–6 mm, lateral lobes 10–14 × 4–7 mm, and ventral lobe 8–10 × 5–6 mm; the synandrium warty, exserted up to 3 cm long; and the berries not inflated (versus the stems, peduncle, and calyx lobes glabrescent to puberulous (not strigose); hypanthium glabrous; petiole glabrescent to slightly strigose; the leaf blade not bullate, with margin subentire, toothed, apex acute to acuminate, and 5 to 8 secondary veins per side; the peduncle 1.5–1.8 cm long; the calyx lobes ascending; the corolla smooth above and beneath, with dorsal lobes 8–10 × 3–4 mm, lateral lobes 7–8 × 3–4 mm, and ventral lobe 6–7 × 2.5–3.5 mm; the synandrium smooth, exserted up to 1.4 cm long; and the berries inflated in B. loejtnantii).
