LATE EARLY

Common Name Sandi's Epidendrum [Type occurs on his property in Costa Rica]

Flower Size .4" [1 cm]

Found in Costa Rica in very humid, lower montane forests on the Pacific slopes at elevations around 1900 meters as a small sized, cool growing epiphyte with thickened into a sub-orbicular to ovoid pseudobulb carrying 1 or 2 apical, coriaceous, ovate-elliptic, bilobed leaves that blooms in the late summer and early fall on a terminal, erect, racemose, arising from a newly developing growth, peduncle, 1" [2.5 cm] long, laterally compressed, enveloped by 1 oblong, triangular, obtuse bract, rachis terete to somewhat flattened, straight, short, hidden by the floral bracts, 3.2" [8 cm] long, simultaneously 3 flowered inflorescence and carrying flowers that completely turn yellow with age.

"Epidendrum sandiorum belongs to the GROUP Coilostylis which is characterized by the sympodial, caespitose plants, the stems forming a fusiform pseudobulb, with an apical, racemose, distichous inflorescence, the peduncle covered by large bracts (but not spathaceous bracts), and large flowers, star-shaped, with long, narrow sepals and petals. The species is recognized by the sub-spherical to ovoid pseudobulbs with a single apical leaf, the inflorescence produced from the immature stem, 3-lobed lip with the outer margin of the lateral lobes fimbriate to laciniate, and the 1.8 " [45 mm] long mid-lobe trullate beyond the middle, apex long-acuminate, the margin erose. Epidendrum oerstedii Rchb.f. ranges from Honduras to central Panama, produces the inflorescence from the immature, short pseudobulb, the margin of the lip is entire, and the mid-lobe shorter 1 to 1.32" [25 to 33 mm] long, widened beyond the middle. Epidendrum ciliare L. is widely distributed from western Mexico (Nayarit) to Peru and Brazil and the Antillies, also produces the inflorescence from the immature, more elongate pseudobulb, but the outer margins of the lip are deeply fimbriate, and the mid-lobe is linear, not widened in the middle. Epidendrum megalemnum Carnevali & G.A. Romero flowers from the mature stem and the base of the inflorescence is enveloped in 5 to 10 imbricating bracts, this species is sympatric with E. ciliare, shares the same shape of the lip and ranges from the lesser Antilles and northern South America."
