Common Name The Three Spot Pollardia [refers to the three Calli on the Column]

Flower Size 1 1/4" to 1 1/2" [3 to 4 cm]

Endemic to Nayarit, Jaslisco, Guerrero, Mexico, Morelos, and Oaxaca states of Mexico on oaks at altitudes of 1200 to 2000 metersas a small sized, cool growing, epiphytic, deciduous species with ovoid to ovoid-ellipsoid, slightly compressed, closely clustered pseudobulbs partially enveloped basally by a few scarious sheaths and carrying 2 to 3, apical, narrowly elliptic, acute to obtuse, gradually narrowing below into the conduplicate, basally clasping leaves that are deciduous in the winter and starts a new growth in the spring as well as blooms on an old leafless growth in the spring and early summer on an apical, length of the leaves or less, arising from the apice of an older leafless, ellipsoid to ovoid pseudobulb as a new growth appears, 1.6" [4 cm] long, 1 to 5 flowered inflorescence with ovate, acute, carinate, membraneous floral bracts and carrying showy, resupinate, very fragrant flowers.

Pollardia micropus is recognized by the deciduous leaves, absent in the winter and the contrasting coloration of the lip and the column, the former creamy-white and the latter deep bluish purple with the apical teeth yelloow. The obovate líp, sometimes with rudimentary lateral lobes is also characteristic. Hagsater 1990

CAUTION !!! Withner & Harding in 2004 moved Encyclia tripunctata to Pollardia tripunctata but they used Epidendrum tripunctatum Lindley 1853 Nom illegal as the basionym which is known as a synonym of Anacheilium calamaria. They should have cited Epidendrum tripunctatum Lindley 1841 as the basionym which would have made the name Pollardia tripuntata valid. As it is Epidendrum micopus is the next available name and ergo the need, within my framework, for the name Pollardia micropus (Rchb.f.) in ed.

Mounting on branches or tree fern seems to be the way to go and they need a slightly cooler and drier winter.
