Fragrant Part shade Cold to WarmMOSTLY LATE Springand Summer

Common Name Umbelled or Different Epidendrum

Flower Size less than 1 1/4" [less than 2.85 cm]

This is a variable sized, cold to warm growing, pendant or erect, caespitose, epiphytic species from the tropical Americas up to elevations of 3000 meters with numerous, leafy, flexuous stems enveloped completely by persistent sheaths carrying leathery to fleshy, oblong to elliptic-lanceolate, obtuse, basally clasping leaves and may bloom at any time during the year but mostly in the late spring and summer on a short, umbellate 1 to many flowered, racemose inflorescence subtended by a large spathe with fragrant, transluscent green or white flowers.

This species in a wide view includes many species that are now being split away. I have split some of these species away that I feel from personal observation visually seem different. These species include, Epidendrum apaganum, Epidendrum campacchii and Epidendrum umbelliferum each differing mostly in the form that the plant takes more than the flowers. See each individual species to see the differences.
