Discussion:
Type. GUYANA: Membaru-Kurupung Trail, 1000 m alt, 29 Oct-4 Nov 1951; epiphyte; leaves stiff, waxen, with revolute margins; flowers pink, waxen; calyx lobes green; ovary deeply sulcate; corolla tube sulcate; Maguire & Fanshawe 32430 (holotype NY; isotype US). Paratype. GUYANA. Kurupung, 12 Nov 1922, Lang & Persaud 157. This taxon is very distinctive in having remarkably narrow leaves with long caudate apices. As compared with the Colombian C. angustifolia Mansf., of similar appearance vegetatively, our taxon has longer leaf blades with longer apices and revolute margins, fewer-flowered inflorescences with longer bracts and pedicels, and different calyx glands.
