  • Description

    Species Description - Erect or ascending herb, 5-50 cm tall, the stems and inflorescence pilose with at least some of the hairs gland-tipped. Leaves petiolate; blades ovate, 0.9-4.5(-5.8) x 0.6-2.8(-4.2) cm, acute to almost obtuse, rounded and often somewhat dimidiate at base, pilose on both sides, the margins crenate or serrate; petioles 1-13 mm. Inflorescence with pedicels 0.5-2 cm, ± straight. Sepals green, elliptic to ovate, 1.7-4 x 1.8-3.6 mm at anthesis, subacute, externally sparsely pilose, internally glabrous, the margins ciliate, entire. Corolla close to type X, light yellow, the throat with a reddish crossband or a series of two to several spots in the throat; upper lip arched, 2-4 x 35 mm, strongly acuminate and tapering to an abruptly truncate apex 1-2 mm wide; lower lip 4-9 x 4-8 mm, saccate in 40-60% of its length; elaiophore present. Stamens with anthers elliptic, yellow, 0.5-0.9 mm long; filaments filiform, 1.4-2.5 mm. Style 1.2-2 mm, straight, decurved near apex. Capsule conical, acuminate, 4-7 mm long, glandular-pilose, greenish-white, thin-walled, slightly translucent. 2n = 36 (Løjtnant & Molau 15185).

  • Discussion

    This species is easily recognized by the acuminate upper corolla lip, sheathing the style as well as the stamens.

  • Distribution

    Ranging in the Andes from central Colombia to SE Peru, and also in the coastal lomas of central and S Peru. In the Andes it grows in open, often disturbed sites, at altitudes of (70-)1200-2500(-3700) m. In the loma formation (probably the original habitat of the species) it grows at 60-500 m. It is also known from the Galapagos Islands at altitudes of 7601525 m.
