Encyclopedia
Epidendrum mancum Lindl. (1844) is an epiphytic
orchid
that grows in the tropical low elfin
cloud forests of Ecuador
and Amazonas
, Peru
, at altitudes of 2—3 km .
inflorescence which erupts from a large spathe, as is typical of the subgenus E. subg.Spathium
. The small, fleshy, non-resupinate flowers range in color from green to yellowish-green or orange, frequently with red-brown markings which may nearly cover the perianth segments. The sepals are subrotund-oblong, and apically very obtuse. The petals are spatulate with very obtuse and concave apices. The small lip
is adnate to the column
nearly to its apex, is concave at its apex, and has a callus of three low ridges. From peduncle
to column apex is approximately 1 cm; the lip protrudes an additional 2 mm.

Description
E. mancum exhibits a sympodial growth habit, with flattened stems nearly covered by the basal sheaths of the three to four oblong retuse leaves, and a terminal racemoseRaceme
A raceme is a type of inflorescence that is unbranched and indeterminate and bears pedicellate flowers — flowers having short floral stalks called pedicels — along the axis. In botany, axis means a shoot, in this case one bearing the flowers. In a raceme, the oldest flowers are borne...
