Based on Markea lopezii Hunz. Description. Hemipiphytic liana with adventitious roots. Stems sparsely pubescent with simple, uniseriate 4-8-celled, hyaline ochre trichomes 0.5-1.2 mm long, with deciduous apex and a persistent multicellular base giving the surface a tuberculate appearance, stems glabrescent with age. Leaves tightly clustered towards the branch tips, (7-)10-22 cm long, 4-9.8 cm wide, elliptic to broadly elliptic, sparsely pubescent with simple uniseriate 4-7-celled hyaline trichomes 0.8-1.2 mm long on both sides; major veins 4-6 pairs, slightly raised abaxially; base cuneate, slightly asymmetric; margins entire; apex acute to acuminate; petiole (7-)10-19(-25) mm long, densely pubescent with simple trichomes as on the leaves. Inflorescence axillary, simple, ebracteate, 7-35(-50) cm long, ~2-5-flowered, densely pubescent with simple, uniseriate trichomes like those on stems; peduncle 6-24(-39) cm long; pedicels 0.8-1.7(-3.0) cm long, distally winged and thickened. Calyx 3.8-5.6 cm long, 1.4-1.9 cm wide, green, sometimes tinged with purple, densely pubescent with simple, uniseriate trichomes like those on leaves; tube 8-9 mm long; lobes flat, 3.5-4.4 cm long, 1.2-1.4 cm wide, long-triangular, apically long-acuminate, green or green with purple margins, sparsely pubescent with simple uniseriate trichomes on the abaxial side. Corolla 8-11 cm long, the inner corolla diameter 2.5-2.8 cm, hypocrateriform; tube 7-10 cm long, orange and tinged with purple in the throat internally, glabrous; lobes 3.2-3.9 cm long, 3.7-4.1 cm wide, triangular, orange, spreading to slightly reflexed at anthesis, the margins flat and entire, the apex acute, glabrous or with a few minute trichomes along the veins. Stamens 7-8.6 cm long, partially exserted beyond the mouth of corolla tube; filaments 5.3-6.1 cm long, adnate at 1.0-1.3 cm from the base of the corolla tube, purple-tinged, densely pubescent with simple 6-10-celled uniseriate trichomes at the insertion point; anthers 1.9-2.2 cm long, 1.4-1.8 mm wide. Ovary ca. 7.5 mm long, ca. 2.9 mm wide, yellow, glabrous; style 7.9-8.8 cm long, glabrous; stigma clavate. Fruit 2.7-3.2 cm long, 1.5-3.3 cm wide, light green; fruiting calyx persistent, accrescent and fully covering the fruit, the lobes 3-3.3 cm long, 1.2-1.4 cm wide. Seeds numerous, 2.2-2.7 mm long, 1-1.3 mm wide, ochre when fresh, brown when dry, the testa reticulate, the testal cells rectangular in outline. Chromosome number not known. Distribution (Fig. 2 ). Doselia lopezii is endemic to the pre-montane forests of the Colombian Andes in the departments of Antioquia, Caldas, Valle del Cauca and Risaralda. Ecology. Mid-elevation moist forests from 1,700 to 2,100 m elevation. Preliminary conservation status ( IUCN 2022 ). Doselia lopezii is classified as vulnerable (VU) according to the B1a criterion with an EOO of ca. 6,000 km2. The area where it is distributed is severely fragmented and the species is known from fewer than ten localities.. Discussion. Doselia lopezii is the type species of the genus and the easiest species to recognise on account of its showy flowers with large orange corollas (Table 2 ; Fig. 1F, G ). Doselia lopezii has anomalous and apparently unique pollen in the genus with prominent spiny supratectal processes ( Persson et al. 1994 ). Preliminary observations in D. huilensis ( Orejuela et al. 2014 ) and specimens of D. epifita examined by Hunziker (1997, as M. lopezii ) indicate that the pollen of these two species lack these spiny supratectal processes.
