Epidendrum

Native: a large neotropical genus with over 1,100 species; native to tropics and subtropical regions of the American continents, from South Carolina to Argentina; habitats include humid jungles, dry tropical forests, sunny grassy slopes, cool cloud forests, sandy barrier islands
Type: epiphytic, terrestrial, or even lithophytic
Size: quite varied in flower size and appearance; apical, lateral or basal flowers are mostly small to medium in size and often are not marked by a conspicuous display; inflorescences are frequently dense
Flowering: grow in tufts, in racemose inflorescences, sometimes in corymbs or panicles; many species are fragrant; flowers may be produced only once, or during several years from same or new inflorescences
Colors: shades of red-orange, pink and white
Flowering stem: the erect, pendent, or creeping stems are reed-like, simple or branching, or may be pseudobulbs or thickened stems
Growth pattern: sympodial or monopodial
Pseudobulb: producing mostly reed-like stems or thickened pseudobulbs that are roundish or oblong
Known for: common name Reed-Stem Orchid; large and showy inflorescences; fringed lip of some species; long-lasting flowers; can be very aggressive colonizers of disturbed habitat, and many species which were once rare have become more common as the result of human activities
History: genus name (from Greek epi and dendron, "upon trees") refers to its epiphytic growth habit; Carl Linnaeus named this genus in 1763

Characteristics of Epidendrum

- A slit rostellum (small extension or little beak to the median stigma lobe), producing a transparent or white thick and adhesive liquid.

- The sometimes fringed lip or labellum is adnate to (united with) the column forming a nectary tube (but rarely producing nectar), continuing through the pedicel.

- The pollinarium contains four pollinia and sometimes two very reduced pollinia.
