Based on Markea huilensis A.Orejuela & J.M. Vélez


Hemiepiphytic liana with adventitious roots. Stems densely pubescent with simple, uniseriate (2-) 4-7 (-11)-celled, hyaline to ochre-brown trichomes 0.2-1.8 mm long, with a deciduous apex and a persistent multicellular base giving the surface a tuberculate appearance, stems glabrescent with age. Leaves tightly clustered towards the branch tips, 9.0-16.7 cm long, 4.6-11.7 cm wide, elliptic to broadly elliptic, densely pubescent with simple 4-9-celled uniseriate hyaline to dark olive-brown trichomes 0.3-2 mm long on both surfaces; major veins 4-6 pairs, slightly raised abaxially; base cuneate or obtuse, asymmetric; margins entire to undulate; apex usually acuminate, mucronate; petiole 0.4-3.8 cm long, densely pubescent. Inflorescence sub-axillary, simple to branched, bracteate, 18-50 cm long, ca. 2-7-flowered, surface tuberculate and densely pubescent with trichomes as on the stems; peduncle 8.5-39 cm long; bracts foliaceous and linear, 5-6 cm long, 1-2 cm wide; pedicels 1.5-2 cm long, distally winged and thickened. Calyx ca. 3.3 cm long, 1.5 cm wide, dark green with purple margins and reticulate along the veins, pubescent with simple 4-7-celled uniseriate white hyaline to brown trichomes; tube 0.5-0.7 mm long; lobes undulate, 2.7-5.2 cm long, 1.3-1.5 cm wide, lanceolate, apically acuminate with an acumen 0.6-0.9 mm long, green with the main vein and the margins purple-brown, pubescent with simple uniseriate trichomes on the abaxial side. Corolla 8.5-10 cm long, the inner corolla diameter 4.5-5 cm, tubular-campanulate; tube 6.2-6.7 cm long, scarcely pubescent with trichomes similar to those of the calyx, yellowish green with strong purple-tinged reticulation along major and minor veins both abaxially and adaxially; tube differentiated into a narrow base ca. 0.2 cm long and 0.8-1 cm wide and a wide distal portion 4.2-4.6 cm long, ca. 5 cm wide; lobes 2.3-3.3 cm long, 1.6-1.7 cm wide, oblong, reflexed during anthesis, colour similar to that of the corolla tube, the margins revolute, the apex obtuse, glabrous. Stamens 6.1-6.9 cm long, fully exserted beyond corolla tube; filaments 4.7-5 cm long, adnate at ca. 2 cm from the base of the corolla, purplish, densely pubescent with simple uniseriate trichomes at the insertion point like those on calyx; anthers 1.4-1.9 cm long, 1.3-1.5 mm wide. Ovary ca. 7 mm long, ca. 3.5 mm wide, light yellow, glabrous; style 7.3-8 cm long, cream; stigma clavate. Fruit ca. 4.2 cm long, ca. 2.5 cm wide, dark green, exocarp 2-2.8 mm thick when fresh, coriaceous, black when dry; fruiting calyx persistent, accrescent and covering the fruit, appressed at maturity, the lobes 4-5 cm long, 2.2 cm wide. Seeds numerous, 2.6-3.0 mm long, 1.2-1.4 mm wide, ochre when fresh, dark brown when dry, the testa reticulate, the testal cells rectangular in outline. Chromosome number unknown.


(Fig. 2 View Figure 2 ). Doselia huilensis is known only from the Departments of Huila and Putumayo in southwestern Colombia.


Doselia huilensis is found in preserved or partially altered oak forests from 2,200 to 2,300 m elevation.

Preliminary conservation status

IUCN (2022). Doselia huilensis is reaffirmed (following Orejuela et al. 2014) here as an endangered species (EN) according to criteria B1ab [i, iii] based on the small EOO (~750 km2), a small number of known populations, and the highly fragmented condition of the relictual forests where it occurs. The species is known from five collections from three localities. Two of these localities are in the Department of Huila 80 km apart, and one recent collection is known from the Valle del Sibundoy, Department of Putumayo, that extends the species distribution approximately 100 km to the south.


Doselia huilensis differs from all other Doselia species in its tubular-campanulate corollas with fully exserted anthers (Table 2 View Table 2 ; Fig. 1D View Figure 1 ). The species is densely pubescent throughout, which is useful in distinguishing it from other Doselia species that are either glabrescent or less densely pubescent (Table 2 View Table 2 ).
