Common Name Greenwood's Epidendrum [Canadian Orchid Enthusiast in Oaxaca later 1900's]
Flower Size 1.6" [4 cm]
Found in Oaxaca Mexico, Guatemala and El Salvador in oak and pine forests often in cloudy conditions at elevations of 1780 to 2500 meters as a cool to cold growing epiphyte or lithophyte with a simple, terete, straight, cane-like stem arising from the middle internode of the previous stem and carrying 3 to 6, aggregate towards the apex of the stem, alternate, articulate, subcoriaceous, smooth, green, margin entire, narrowly elliptic, acute leaves that blooms in the fall through spring on a terminal, occuring only once, racemose, arching, laterally compressed basally, simultaneously 12 to 32 flowering inflorescence with somewhat less than half the length of the ovary, triangular, acuminate floral bracts and carrying nocturnally, sweetly fragrant flowers.
"Epidendrum greenwoodii belongs to the GROUP Arbuscula SUBGROUP Arbuscula which is characterized by the successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, arching, apical inflorescence with colorful flowers, the lip bicallose. The species has robust plants, a long inflorescence, orange-ochre flowers with the column and lip white towards the base, the apical lobes are short, and the flowers have a weak nocturnal fragrance. Epidendrum camposii Hágsater also has a long, dense inflorescence with pink to rosy white flowers which turn yellowish, the lip white and the lip 3-lobed. It is somewhat similar to E. alabastrialatum Pollard ex Hágsater which has greenish yellow flowers with a white lip and column, the calli orange-yellow, the 4-lobed lip wilh the four suborbicular lobes about equal in size, and the lateral sepals with a prominent dorsal keel which gives the floral buds a winged aspect. Epidendrum nicaraguense Scheeren ex Hágsater is morphologically very similar, but the flowers are somewhat smaller with sepals .64 t .68" [14 to 17 mm] long, sepals and petals are pale pink and turn orange-yellow with time, the calli yellow and the lip white, the inflorescence is generally fewer, 8 to 18 flowered. Epidendrum radioferens (Ames, Hubbardl & C. Schweinf.) Hágsater has magenta-red to burgundy-red flowers with the disc of the lip yellow, the lip entire to 3-lobed, the midlobe short, with 3 central keels and numerous radiating, fleshy thickened veins."
