Common Name Baumann's Epidendrum [French Gardener late 1800's]
Flower Size 1" [2.5 cm]
Found from Mexico, Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Colombia and Ecuador in lowland rainforest, often with antnests or on steep embankments at elevations of 50 to 1000 meters as a large sized, hot to warm growing epiphyte, lithophyte or terrestrial with roots that only arise from the base [a major difference with the related Epi radicans that has roots arising any where on the stem] and erect, non-swollen, cane-like stems enveloped by grayish sheaths and carrying 6 to 10, subcoriaceous, elliptic, bilobed, basally clasping leaves that blooms in the winter through spring on a terminal, to 20" [to 50 cm] long, congested, successively flowered, racemose inflorescence with the several flowers held in an apical umbel. The tall plants, the caespitose stems with roots only at the base, and leaves distrubuted along the emiddle, the elongate peduncle, the successive flowering, the resupinate, yellowish flowers, the lacinate margins of the lip and the erect column distinguish this species.
This species is often found in conjunction with ants and may benefit from their presence.
" Epidendrum baumannianum belongs to the GROUP Secundum SUBGROUP Secundum , characterized by the caespitose habit, numerous oblong, coriaceous leaves, usually elongate peduncle of the inflorescence with a short raceme of flowers, bicallose lip and caudicles of the pollinia, like apile of roof-tiles. The species is recognized by the resupinate, reddish orange flowers, the column, calli and keel yellow, sepals acuminate, .5 to 1" [12.5 to 25 mm] long, oblong, oblique petals with entire margin, very similar to the lateral sepals, .48 to.96" [12 to 24 mm] long, the column with a pair of apical, deltoid, appendices, the lip 3-fobed with a dentate margin. Epidendrum hawkesii Heller has been considered by many authors a synonym of E. baumannianum, they are vegetatively very similar, but the former has oblanceolate, acute sepals, narrowly rhombic petals that are unguiculate at the base and the apical margin erose-dentate. Epidendrum apatotylosum Hagsater has taller plants, up to 60" [150 cm] high, non-resupinate, purplish red flowers with the distal part of the column white, and a pair of truncate, laminar, appendices at the apex of the column are easily confused with calli, the 3-lobed lip has a dentate-fimbriate margin. Epidendrum radicans Pavo ex Lindl. has a creeping habit, with roots all along the ítem, orange reddish flowers, the disc of the lip yellow with a few red dots, sepals and petals are generally spreading, elliptic and acute, the margin entire."
