Common Name The Large Rossioglossum - The Clown Orchid - In Guatemala - Boca de Tigre [Tiger's Mouth]

Flower Size to more than 6" [to more than 15 cm]

Found from Guatemala, Belize and Mexico as a medium to large sized, epiphytic, warm to cold growing orchid that occurs at elevations of 1400 to 2700 meters in moist deciduous, rainforests with a distinct wet, shady [from leaves] spring and summer and much drier and brighter [fallen leaves] fall and winter,with clustered, ovoid or orbicular, laterally compressed, ancipitous, glaucous, pseudobulbs carrying 1 to 3 apical, elliptic or lanceolate, coriaceous, glaucous, acute, petiolate leaves and blooms on an axillary, lateral to erect, to 12" [30 cm] long, racemose, several [2 to 8] flowered inflorescence with lanceolate, apressed, scarious bracts and waxy longlasting flowers all occuring in the late fall and winter.

The easiest way to identify this species when the lip can be viewed well is the the yellow, flabellate, pubescent, suborbicular column wings instead of the thin, elongate, recurved, reddish column wings instead of the rare R williamsianum. Of course there are many other differences including a fewer flowered, shorter inflorescence but the column wings are diagnostic.
