FFE12FEBFEA351FD960BFCB70ED94C93.taxon	diagnosis	Diagnosis. Vegetatively similar to Columnea suffruticosa J. F. Sm. & L. E. Skog due to the presence of ovate leaves with a rust-colored multicellular hispid indumentum, but differing in the terrestrial habit (vs. epiphytic habit in C. suffruticosa) and deeply bilabiate corolla (vs. uniformly tubular corolla in C. suffruticosa). The deeply bilabiate corolla, dark purple corolla tube, and glandular trichomes throughout the upper and lower lobes are unique characters not found in any other known species of Columnea.	en	Clark, John L.

FFE12FEBFEA351FD960BFCB70ED94C93.taxon	description	Description. Terrestrial subshrub with dorsiventral shoots, 1.0 – 1.5 m tall, stems green with densely pilose rust to gold-colored multicellular hispid indumentum; internodes 1.0 – 2.5 cm long. Petioles 1.0 – 2.5 cm long, red, with densely pilose to gold-colored multicellular hispid indumentum; leaves opposite, pairs strongly anisophyllous, larger leaf 9.0 – 15.0 cm long, 4.0 – 7.0 cm wide, ovate-elliptic, apex acuminate, base rounded and slightly oblique, lateral veins 5 – 9 per side, adaxially light-green, with multicellular hispid indumentum, abaxially uniformly-red, with multicellular hispid indumentum, more densely pubescent on veins, margin entire; smaller leaf 1.0 – 2.0 cm long, 0.9 – 1.5 cm wide, lateral veins 2 – 3 per side, petiole 1 – 2 mm long, otherwise similar to larger leaf. Inflorescence reduced to 1 – 3 axillary flowers; bracts triangular, green, 2 – 3 mm at base, apex broadly acuminate. Pedicels 1.0 – 1.8 cm long, dark red, densely pilose with multicellular rust-colored hispid indumentum. Calyx lobes uniformly green or green suffused with red, 1.0 – 1.7 cm long, 0.5 – 0.7 cm wide at base, oblong, apex acuminate, exterior pilose, with multicellular rust-colored hispid indumentum, interior glabrous, margin mostly entire or with 1 – 3 serrations. Corolla 5.0 – 6.2 cm long, 2.0 cm at widest (apex) point, deeply bilabiate, lower lobe recurved, 1.8 – 2.2 cm long, 3 – 4 mm wide, lateral and upper lobes fused into a hood, lateral lobes reflexed, rounded, 5 mm at base with acuminate apex, upper lobes fused, 1.0 cm wide, 1.3 cm long, apex bilobed, each lobe rounded, densely pubescent with multicellular rust-colored trichomes, interior uniformly dark purple, covered with glandular trichomes, occasionally with yellow margins, especially along the lower lobes, outer surface dark purple to dark purple suffused with yellow. Filaments ca. 3.5 cm long, connate at base for 0.3 cm and adnate to corolla, anthers ca. 3.0 mm long, 3.0 mm wide, included in the corolla throat, quadrangular. Ovary ca. 4.0 mm long, conical, glabrescent; style 3.5 – 4.0 cm long, glabrescent, stigma rounded. Nectary comprised of one large dorsal and two smaller lateral glands. Fruit not observed.	en	Clark, John L. (2025): Columnea golondrinensis (Gesneriaceae), a new species from Cerro Golondrinas in the northern Andes of Ecuador.

FFE12FEBFEA351FD960BFCB70ED94C93.taxon	etymology	Etymology. The specific epithet reflects the type locality, Cerro Golondrinas, where this species is presumably endemic.	en	Clark, John L. (2025): Columnea golondrinensis (Gesneriaceae), a new species from Cerro Golondrinas in the northern Andes of Ecuador. PhytoKeys 253: 1-9, DOI: 10.3897/phytokeys.253.144114
FFE12FEBFEA351FD960BFCB70ED94C93.taxon	distribution	Distribution and preliminary assessment of conservation status. Columnea golondrinensis is only known from a single population on a ridgeline in Cerro Golondrinas. The region is protected by the recent acquisition and purchase of forest by Fundacion EcoMinga. The forest corresponds to the Chocó Biogeographic Region for the relatively high levels of precipitation and epiphytic diversity. Based on the available information and according to the IUCN Red List criteria (IUCN 2012; IUCN Standards and Petitions Committee 2024), C. golondrinensis is preliminarily assessed as Vulnerable (VU) based on a limited area of occupancy (IUCN criterion D 2 where AOO <20 km 2) and limited number of locations (<5).	en	Clark, John L.
