Common Name Boeke's Epidendrum [Orchid Enthusiast in Ecuador late 1900's]

Flower Size 1.2" [3 cm]

Found in Cusco department of Peru at elevations around 2500 meters as a medium sized, cold growing epiphyte with the new cane arising from the middle internode of the older cane carrying 2 to 3, narrowly elliptic, herbaceous leaves that blooms in the spring on a terminal, arcuate, racemose, occuring only once, 2 to 2.4" [5 to 6 cm] long, peduncle laterally compressed, simultaneously, 5 to 7 flowered inflorescence arising on a mature stem without a spathe, and with a triangular, acute, shorter than the ovary floral bract.

"Epidendrum boekei belongs to the GROUP Arbuscula SUBGROUP Incomptum, which is characterized by the successive lateral growths, few leaves aggregate towards the apex of the stems, arching, apical inflorescence with fleshy green to black flowers, the lip bicallose entire to 3-lobed. The species is recognized by the stems produced from the middle of the previous stem, with few leaves aggregate near the apex, the racemose inflorescence and the fleshy, pale green to greenish yellow flowers with oblanceolate, 3-veined petals, the 3-lobed lip with the lobes subequal in size, the laterals somewhat obliquely obovate, the midlobe subquadrate, shallowly marginate. It is very similar to E. homoion which is larger overall, the sepals are wider and obtuse, the petals obtrullate, the lip .56 to .64" x 1.04 to 1.12" [14 to 16 x 26 to 28 mm] has proportionately larger semi-orbicular lateral lobes, and a smaller emarginate midlobe. Epidendrum tamaënse Foldats has larger flowers with sepals .6 to 1.04" [15 to 21 mm] long, obtrullate petals .28" [7 mm] wide, the lateral lobes of the lip suborbicular and the midlobe widened towards the apex. Epidendrum curtisii A. D. Hawkes has 3-lobed, bicallose lip, sub-orbicular lateral lobes, the midlobe somewhat wider than long, sepals .32 to .42" [8 to 10.5 mm] long, and the oblanceolate, 3-veined petals."
