Overview
Caespitose epiphytes. Pseudobulbs ellipsoid-suborbicular, compressed. Leaves two, arching. Inflorescences long-pedunculate pendent racemes emerging from the new growth, the floral bracts inconspicuous. Flowers showy, fragrant, long-lasting. Sepals and petals subsimilar, subequal, free, spreading. Lip bilobulate, fan-shaped from a long claw, the callus fleshy. Column short, straight, with three conspicuous terminal wings; pollinia 2, on a common stipe and viscidium.
Etymology
Named to honor Cuitlahuatzin, Governor of Iztapalapa and patron of horticulture.
Distribution
A monotypic genus endemic to Mexico; closely allied to Osmoglossum Schlechter and Palumbina Reichenbach and formerly included in a broadly defined Odontoglossum.
Care and Culture Card
See basic growing conditions and care information below.
Grow plants of Cuitlauzina in baskets or shallow pots of medium-grade epiphyte mixture. Suspend the containers and provide airy conditions of bright light, copious air movement, and cool-intermediate temperatures. Water regularly after the emergence of new growth; provide only maintenance levels of water after the pseudobulbs mature. Plants of Cuitlauzina are highly susceptible to root disturbance and should only be repotted (with minimal disturbance of the root ball) when necessary and after the new growths show visible signs of new roots. Often difficult to flower in cultivation, plants of Cuitlauzina flower best when pot-bound and(or) grown to large size.
