Common Name Parkinson's Epidendrum[English Consul in Mexico and Orchid Enthusiast 1800's]

Flower Size to more than 6" [to more than 15 cm]

This large sized, cool to cold, pendant growing, epiphytic species is found in Jalisco, Morelos, Oaxaca, Puebla, Vera Cruz, and Chiapas states of Mexico, Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica and Panama in oak-pine cloud forests at elevations of 1000 to 2300 meters with cylindrical, curved, 3" [7.5 cm] long pseudobulbs enveloped basally by a few scarious, tubular bracts carrying a single apical, pendulous, fleshy, narrowly lanceolate, entirely folded leaf. The apical, 2" [5 cm] long, racemose inflorescence arises from within the base of the folded leaf with 1 to 3, large, longlasting, simultaneously opening, fragrant [citrus] flowers arising from a newly forming pseudobulb and may occur at various times of the year.

"Epidendrum parkinsonianum Hook. belongs to the GROUP Coilostylis SUBGROUP Falcatum , characterized by the pendent, sympodial, caespitose habit, roots only at the base of the first stems, a single, fleshy, succulent, lanceolate leaf, the large, star-shaped flowers, and the deeply 3-lobed lip. The species is epiphytic, has thin stems, carrying 1 to 3 large flowers and but larger flowers with sepals 1.8 to 3.8" [45 to 95 mm] long, sepals and petals green, the lip white, except for the yellow calli. It is very similar to Epidendrum falcatum Lindl. but it is lithophytic, has 4 to 8 flowers, thickened, brittle stems, and the flowers are similar in size with the sepals 1.2 to 2.08" [30 to 52 mm] long with the sepals and petals pink, lip white, except for the yellow calli. Epidendrum ixilum is also epiphytic, also has thin stems, and 1 to 3 smaller olive-flowers with green sepals 1.68 to 1.72" [42 to 43 mm] long and petals, somewhat tinged copper, the lip white at the base, with the mid-lobe pink, copper colored and green apically. The color is reminiscent of Epidendrum lacertinum Lindl., but that species has thickened, pseudobulbous stems, and the inflorescence many-flowered." Adapted from Plate 1529 Hagsater etal 2015
