Epidendrum, abbreviated Epi in the horticultural trade, is a large neotropical genus of the orchid family. With more than 1,500 species, some authors describe it as a mega-genus. The genus name refers to its epiphytic growth habit.
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 are only 2.9 mm long.
Epidendrum fulgens is a crucifix orchid native to Brazil. Like E. secundum, with which it has been found to hybridize in habitats disturbed by human activity, E. fulgens flowers are non-resupinate and are born in a congested raceme at the end of a long spike. Like all crucifix orchids, the lip is adnate to the column and bears three lobes, producing the effect of a cross. Like E. cinnabarinum, E. denticulatum, and E. puniceoluteum, E. fulgens grows in the litoral restinga habitat.
Epidendrum flexuosum, a reed-stemmed Epidendrum common at mid-altitudes in Central America, is a species of orchid commonly called Epidendrum imatophyllum. It grows exposed to intense sunlight in the forest canopy, particularly on Guava species. E. flexuosum bears non-resupinate lavender flowers on a congested raceme at the end of a long peduncle.
