About Prosthechea citrina (Lex.) W.E.Higgins
Prosthechea citrina is an epiphytic orchid species that produces both pendant growth habit and pendant flowers. It is a compact plant with tightly clustered pseudobulbs that measure 4–6 cm (1.6–2.4 in) long and 2–3 cm (0.79–1.18 in) wide, and have a persistent papery outer surface. Each pseudobulb grows 2 to 4 silvery-green leaves; the leaves are elliptical in shape, with an acute tip that is also closely obtuse, and reach 18–25 cm (7.1–9.8 in) long and 2–4 cm (0.79–1.57 in) wide. The foliage is distinct for the fine powdery film that covers its surface. This species uniquely grows hanging upside down from the trunks or large branches of larger trees, and most often occurs in rather cool, dry forest environments located at elevations between 1,300 and 2,200 m (4,300–7,200 ft). In terms of distribution, Prosthechea citrina grows as an epiphyte on trees in mixed oak-pine forests of central and southern Mexico. Documented specific locations include: Leonardo Bravo in Guerrero; Mascota in Jalisco; Madero in Michoacán; and Mpio. San Pedro Juchatengo, Santo Domingo Albarradas, and Dto. Teposcolula in Oaxaca.
