Common Name Alvarez's Odontoglossum [Colombian Orchid Enthusiast and my personal friend current]

Flower Size 1.6 to 2" [4 to 5 cm]

Found in Cundinamarca department of Colombia on the eastern slopes of the Cordillera Ortiental in cloud forests at elevations of 2800 to 3000 meters as a small sized, cold growing epiphyte with ovate-acuminate, slightly flattened laterally pseudobulbs enveloped basally by several, opposite leaf bearing sheaths and carrying 1 to 2, apical, narrowly lanceolate-acuminate leaves that blooms in the late fall and winter on an axillary, from the foliar sheath, erect to somewhat arcuate, straight, to 8" [20 cm] long, provided with 2 bracts, 2 to 5 flowered inflorescence with appressed, scale-like, much shorter than the ovary floral bracts and carrying slightly campanulate, spidery flowers.

Closely related to the Ecuadorian and Peruvian species O tenue but O alvarezii is a larger plant, a much longer inflorescence, different colored sepals and petals, a clearly different lip and the anther is different.
