Striking bright purple flowers. Epidendrum secundum, one of the crucifix orchids, is a poorly understood reed stemmed species, which Dressler (1989) describes as “the Epidendrum secundum complex.” According to Dressler, there are dozens of varieties, some of which appear to deserve species rank. Arditti and Ghani note that E. secundum has the distinction of bearing the longest seeds known in the Orchidaceae, 6.0 mm long. By comparison, the seeds of E. ibaguense (another crucifix orchid) are only 2.9 mm long. Like the other members of E. subg. Amphiglottium, E. secundum is a sympodial plant which has thin stems covered from the base with imbricating sheaths which are leaf bearing above, a terminal inflorescence covered at its base with thin imbricating sheaths, and flowers with the lip adnate to the column to its apex. The flowers are non-resupinate (unlike E. ibaguense and E. radicans), can come in shades of lilac, red, orange, or yellow, and feature a notable callus on the fringed trilobate lip. The plant is rather cool-growing and can tolerate a light frost.
