Originally published by Oakes Ames & C. Schweinfurth in: Ames, Schedulae Orchidianae No. 8, 54 (1925).

The name "mucronata" means "having mucros" -- sharp, terminal points. This species is distinguished by having three small "teeth" on the tips of the leaves, the floral bracts, and on the column wing tips. The plants grow about 1 ft tall (30 cm) in cultivation, and up to 3 ft (1 m) tall in their natural habitat (both epiphytically and terrestrially). The leaves are hard and stiff, with stellar hairs covering the under (dorsal) side.

The flowers are white and somewhat cupped, with the backs of sepals being greenish. The lip is white with and orange area in the center and two pale-yellow keels; the column is white. See the article by Teuscher (1965) for a full detailed description of the floral parts. Flowers appeared in cultivation in Canada in July and August.

This species is evidently rare everywhere. Observed in three provinces of Costa Rica at 500 m, 550 m, and 1000 m elevation, blooming in November (Alajuela, Heredia, and Guanacaste). Specimen collected at Monteverde, voucher # 10152. William Haber noted that a specimen at 1000 m was an "epiphyte on tree trunk in pasture. Flower pale yellow, lip shaded with maroon;" Stephen Ingram noted that a plant from 550m was an "Epiphytic on fallen branch. Sepals white, spreading; petals white; throat white with yellow groove down center; lip with raised, wavy calluses marked with yellow, margins fimbriate." It is known in Costa Rica as the " One Day Flower"
