to through LATE

Common Name The Toothed Epidendrum

Flower Size 1" [2.5 cm]

Found in Brazil in full sun where it is quite commonly found from Pernambuco to Rio Grande do Sul State and I suppose even in Uruguay at elevations of 1000 meters in dry scrub as a, large sized, warm to cool growing terrestrial with cane-like stems carrying 10 to 16, thick, leathery leaves and blooms from the winter through late summer on an apical, many flowered inflorescence with color variable flowers.

As most of the Epidendrums of the GROUP Secundum SUBGROUP Secundum, we can grow it easily in the ground and soon it will turn into a huge specimen plant. It can be distinguished from other similar species due to the two roundish yellow callus on the lip. There are several different colors of this species.

"Epidendrum denticulatum belongs to the GROUP Secundum SUBGROUP Secundum, which is characterized by the caespitose habit, simple, terete, stems, numerous, oblong-elliptic, bilobed leaves, mostly elongate inflorescence, with a raceme of successive flowers, the lip with two calli and a prominent, flexuous keel. The species has somewhat acuminate sepals and petals, the petals with non-branching veins and entire margins, the midlobe of the lip proportionately larger, and a white spot on the disc covering more than the calli. It closely somewhat resembles Epidendrum franckei with the non-resupinate, pink flowers flowering simultaneously, the apex of the column and calli white, obtuse sepals and petals, the erose petals somewhat wider than the sepals and the lip with large, extended, semiorbicular lateral lobes and a smaller, bifid midlobe."
