description: 33. Burmeistera multiflora Zahlbr., Repert. Nov. Spec Regni Veg. 13: 530. 1915.   
 Type:— ECUADOR: “Sive Andium Quitensium, Crescit in Andium Nematris, alt. 8000 ped., floret. August”, (fl), W. Jameson 542 (lectotype P! [P00408891], designated here). Figs. 17, 18E –F.   
 Burmeistera armadana E.Wimm., Repert. Spec. Nov. Regni Veg. 29: 54. 1931, syn. nov. Type:— COLOMBIA. Nariño: Ricaurte, “prope Armada”, s.d., E. André et al. 1521 (holotype: K! [K000250840]).   
Upright herbs or shrubs up to 1.8 m tall. Stem glabrescent to puberulous. Petiole 0.5–3.5 cm long, glabrescent to slightly puberulous; blade elliptic to obovate, 9–28 × 4–14 cm, glabrous above, glabrescent or more often minutely puberulous especially along the veins beneath, base attenuate, acute, frequently slightly asymmetric, apex acuminate, margin subentire to slightly toothed, with 1 to 3 extramarginal or marginal hydathodes per cm, secondary veins 11 to 15 per side, intramarginal vein lacking. Flowers ca. 10‒25 per twig, crowded in the distal corymbiform region of the twig, this region 15–25 cm long, each flower subtended by a reduced (1.0–2.5 × 1.0– 1.5 cm), bracteiform leaf. Peduncle 2.7–6.5 cm long, glabrescent to puberulous, gradually joined to the hypanthium, ebracteolate. Hypanthium narrowly cylindric to subglobose, 5–7 × 3–6 mm, glabrescent. Calyx lobes narrowly ovate, 3–11 × 1.5–3.0 mm, reflexed to ascending, glabrescent or glabrous, basally contiguous, margin entire to sinuous, occasionally with 3 or 4 projections, apex rounded. Corolla green, glabrous; tube 7–16 mm long, 3–4 mm in diameter at its mid-level, slightly inflated proximally and distally; lobes narrowly ovate, falcate, apex acuminate, dorsal lobes 9–14 × 3.0– 3.5 mm, lateral lobes 6–9 × 3–4 mm, ventral lobe 5–6 × 3–4 mm. Synandrium 2.2–3.5 cm long, exserted up to 2 cm; filament tube 1.9–2.8 cm long, glabrous; anther tube 3–7 mm long, glabrous, ventral anthers barbate, with an apical tuft of villous trichomes during pre-anthesis and early anthesis, later ebarbate. Berries globose, 5–15 × 8–13 mm, not inflated, glabrous to glabrescent, green, bright yellow, reddish or pink.  
 Phenology: — Burmeistera multiflora sets flowers and fruits throughout most of the year.   
 Distribution, ecology and conservation status: — Burmeistera multiflora is found in Colombia and Ecuador. In Colombia it occurs primarily in cloud forests at elevations between the sea level and 2900 m in the Western Cordillera and edges of wetforests of the Pacific region, in the departments of Chocó, Nariño, Risaralda and Valle del Cauca, plus two isolated localities in the Central Cordillera, in the department of Cauca. Following the IUCN (2022) Guidelines, it is highly likely that this species is not threatened.   
 Notes: — Burmeistera multiflora is similar to B. fistulosa (see distinctive traits under the latter).   
 Burmeistera multiflora was described based on the following three syntipes: Ecuador: “Quito, Nanegal (l. Karsten in Herb, Vindob.); Andes Quitensis (Jameson no. 542, in Herb. Paris); in silvis montis Corozón, 1600‒2000 m.s.m. (Sodiro no. 91/29, in Herb. Berolin)”. Only one of them (Jameson 542, deposited at P [P00408891; http://mediaphoto. mnhn.fr/media/1441351980662OdS50QSIwDLenx5o) was located. This specimen is here designated as the lectotype, as it has the distinctive vegetative and reproductive traits of the species, and agrees with the protologue description. There is a fourth collection (“circa Canzacoto, 1600‒2000 m, Sodiro 91/27 ”), deposited at P [P00408893], which likely corresponds to a duplicate of the specimen Sodiro 91/29. Although this additional collection corresponds to B. multiflora, its number and locality do not correspond exactly with the protologue, which precludes its status as a syntype.   
 In the original description of Burmeistera multiflora, Zahlbruckner (1915) described the presence of subulate bracts at the base of the peduncle. A detailed examination of the type collection clearly demonstrates that the peduncle is ebracteolate, and that the so-called bracts correspond to the extremely reduced, bracteiform leaves that subtend the flowers, and that occur in species with corymbiform inflorescences.   
 After a careful examination of the type specimen and the original description of Burmeistera armadana, no differences were detected that would allow treating it as different from B. multiflora. Therefore, it is reduced to the synonymy of the latter. The type locality of B. armadana (“prope Armada”, recorded in the type specimen E. André et al. 1521), corresponds to the “quebrada” and the station known as “La Armada”, in the municipality of Ricaurte (Nariño).
