Common Name The Toothed Lip Epidendrum [refers to the small basal tooth on the lateral lobes of the lip]

Flower Size 1" [2.5 cm]

Found in Panama, Colombia, Fr Guiana, Guyana and northern Brazil in lowland rainforest at elevations around 50 meters as a small to medium sized, hot growing epiphtye with erect, slender, simple, terete, straight to flexuous, canelike stems carrying 6 to 12, distributed towards the apical half of the stem, , subcoriaceous, articulate, narrowly elliptic to lanceolate, basally clasping, acute, mucronate, margin entire, green, sometimes tinged purple leaves that blooms in the late summer and early fall on a terminal, without a spathe, produced from the mature stem, occuring only once, arching-nutant, peduncle short, with 1 to 3 conduplicate, oblong-triangular, acute, spaced bracts, rachis laterally compressed at the base, arching, un-ornamented, slightly zigzag, racemose, rarely paniculate, with 1 or 2 short branches, .8 to 2" [2 to 5 cm] long, simultaneously, opening from the middle of the inflorescence towards the base and apex, 4 to 40 flowered inflorescence with much shorter than the ovary, amplexicaul, triangular, acute floal bracts and carrying resupinate, distichous, waxy, ivory-white or cream-colored, flowers slightly sweet-green fragrant diurnally, during night-time lemon scented.

"Epidendrum dentilobum belongs to the GROUP Coronatum SUBGROUP Coronatum characterized by the relatively large plants with stems carrying many leaves and blooming on an apical, racemose inflorescence without spathaceous bracts and large waxy flowers with a 3 lobed lip that is basally bicallose. The species is recognized by the caespitose habit, with several fleshy leaves along the apical half of the thick stem, the racemose to paniculate, apical, few-flowered inflorescence, the flowers greenish-yellow with reddish brown spots, with the lip only partly united to the short, conical column and forming a wide cavity, the lip 3-lobed, with the lateral lobes small and triangular, and the midlobe semicircular, flabellate, and the base of the lip with two short calli and a horn-shaped, short keel in the middle, similar to the calli. We cannot place the species very close to any other. The plant habit is superficially similar to Epidendrum coronatum Ruiz & Pavón, but that species has larger, more numerous, ivory-white flowers with the lateral lobes of the lip dolabriforrn and much larger than the midlobe. The flowers are somewhat reminiscent of Prosthechea vespa (Vell.) W.E. Higgins, due to the brightly spotted sepals and petals, and the fleshy, toothed clinandrium-hood, though that species has long thin pseudobulbs with apical leaves, and an erect, simple inflorescence with non-resupinate flowers."
