Burmeistera aeribacca E.Wimm., Brittonia 8: 108. 1955 . Type:— COLOMBIA . Cundinamarca : Cordillera Oriental, Caraucha Range, east of Ibama, 13 km east of Yacopí, near the Boyacá border, 2290 m , 8 May 1944 (fl), M. L. Grant 9153 ( holotype : MICH! [MICH1111455]; isotypes: US ! [00146930], WIS! [WIS0256491]). Figs. 2A–D , 3 . Epiphytic subshrubs up to 2 m tall. Stem glabrous. Petiole 5‒15 mm long, glabrous; blade ovate to elliptic, 5‒12 × 1.8‒5.0 cm, glabrous above and beneath, base rounded to obtuse, slightly asymmetric, apex acuminate, margin entire to loosely toothed, hydathodes marginal, secondary veins 6 to 9 per side, intramarginal vein lacking. Peduncle 4.5–6 cm long, glabrous, ebracteolate. Hypanthium urceolate, 7‒9 × 4‒6 mm , glabrous. Calyx lobes broadly ovate, 1‒3 × 0.5‒2.0 mm, ascending, glabrous, basally contiguous, margin entire, apex obtuse. Corolla uniformly green, glabrous; tube 10‒17 mm long, 2.6‒3.0 mm diameter at its mid-level, inflated proximally and distally; lobes narrowly ovate, falcate, apex acute, dorsal lobes 12‒14 × 2‒3 mm , lateral lobes 8‒10 × 1.5‒2.0 mm, ventral lobe 5‒7 × 1‒2 mm . Synandrium 3.0‒ 3.1 cm long, exserted up to 1.5 cm ; filament tube 2.3‒2.4 cm long, puberulous; anther tube 6‒7 mm long, glabrous, apex uniformly ciliate, ventral anthers ebarbate. Berries ellipsoid to subglobose, 3.0–4.5 × 1.5–3.0 cm, inflated, glabrous, luteo-greenish to pinkish. Phenology: —The species sets flowers and fruits in January, February, April to July, September and October. FIGURE 2. A–D.

I–L. B. asclepiadea ( Rusby & Pennell 793 , type), leaf (I), leaf margin (J), flower (K) and berry (L). White arrows in A, E and I point to ascending, secondary veins; white arrowheads in B, F and J point to third order veins; black arrows in F and J point to intramarginal veins; black arrowheads in B, F, and J point to hydathodes. Scale bars: 1 cm in A, E, I; 1 mm in B, F, J; 5 mm in C, D, G, H, K, L. FIGURE 3. Distribution of Burmeistera aeribacca , B. andakiana , B. antioquensis , B. asclepiadea and B. betancurii . Distribution, ecology and conservation status: — Burmeistera aeribacca is endemic to Colombia . The species occurs in cloud forests of the Eastern Cordillera, in the departments of Cundinamarca and Santander , and the Central Cordillera, in the departments of Antioquia , Caldas and Tolima , at elevations between 1200 and 3100 m . Following the IUCN (2022) Guidelines, this species qualifies for the Near Threatened (NT) category. Notes: — Burmeistera aeribacca is similar to B. kalbreyeri , from which it differs by its leaf blades glabrous beneath, with 6 to 9 secondary veins per side and acuminate apex, calyx lobes broadly ovate, 1‒3 × 0.5‒2.0 mm, ventral anthers ebarbate all the way through, and berries 3.0‒4.5 × 1.5‒3.0 cm ( versus the leaf blades glabrescent or sometimes sparsely puberulous along the major veins beneath, with 8 to 14 secondary veins per side and obtuse to acute apex, calyx lobes ovate, 3–8 × 2.0– 3.5 mm , ventral anthers barbate during preanthesis, and berries 1.6–2.2 × 2.0– 2.5 cm in B. kalbreyeri ).
