Part Shade Cold Winter

Common Name The Luer’s Odontoglossum [American Botamnists and Pleurothallidinae experts]

Flower Size

Found in Carchi province of Ecuador in high elevation cloud forests at elevations around 2000 to 2500 meters as a natural hybrid between O. armatum and O. mirandum as a small sized, cold growing epiphyte with caespitose, ovoid and longitudinally wrinkled with age, basally sparsely spotted with purple pseudobulbs enveloped basally by 5 to 6 distichous sheaths, the uppermost foliaceous and carrying a single, apical, erect, narrowly elliptic and acute, conduplicate below into the petiolate base leaf that blooms in the winter on an axillary from the uppermost sheaths, erect to arching, almost straight to indistinctly flexuous, to ca. 7.6” [19 cm] long raceme, threeflowered inflorescence with appressed, scale-like, acute floral bracts and carrying stellate flowers.

”Odontoglossum × luerorum is visually similar to both O. armatum and O. mirandum but differs by its intermediate features, such as having erect lateral lip lobes that are distinctly shorter, ca. .1 to .12” [2.5 to 3.0 mm] long versus ca. ,28” [7 mm] long for O. mirandum, but distinctly longer than for O. armatum, which basically lack erect lateral lip-lobes altogether and where the lip is fused to the column by lateral flanks only, as opposed to a short central longitudinal ridge (as for O. mirandum), combined with lateral flank fusion for O. × luerorum.” Dalstrom & Higigns 2019
