Common Name The Serpent Epidendrum

Flower Size 5/8" [1.5 cm]

A miniature epiphytic species found in Colombia, Ecuador, Peru and Venezuela on small trees near the tree line at an elevation around 1600 to 3500 meters in wet montane forests as a mini-miniature sized, cool to cold growing epiphyte with small, ovoid pseudobulbs enveloped almost completely by the clasping leaf base carrying a single, apical, elliptical, acute leaf and blooms in the summer through early winter on several, terminal, short, single flowered inflorescence held in a cluster with the flowers held close to the apex of the newly arising pseudobulb.

This is the type for the Serpens group made up of: E carmelense, smaller overall, long strings of growths, a cordate, reniform lip and sepals to 1 cm long, E oxapampense, with pendant single, glaucous leafed pseudobulbs and resupinate flowers with a wide trullate lip, the margin fleshy-erose, E moronense with pendant single leafed pseudobulbs, a longer and thinner column, a reniform lip with lacerate margins, bicaulose and has a low keel in the center of the lip, E pachacuteqianum with very clustered pseudobulbs carrying one to a few, coriaceous, fleshy leaves with an apical, sessile inflorescence without any spathes and carrying compact, small, non-resupinate, successive, star shaped flowers and E platyphylloserpens with a pendant growth habit, short pseudobulbs carrying a single, wide, elliptic, coriaceous leaf and a terminal erect, sessile, racemose inflorescence and reddish brown successsively opening, non-resupinate flowers. E garayii differs in having the sheaths of the pseudobulbs carrying leaves identical to the apical leaf and E illinazae which has similar leaves but the habit is more elongate and the flowers are solitary, red and with a deeply cordate lip with a finely erose margin.
