Common Name The Almost Square Chaubardiella [refers to the shape of the lip when expanded]

Found in Costa Rica, Panama, Colombia and Ecuador at elevations around 400 to 900 meters as a small sized, hot to warm growing epiphyte with a few subpetiolate, dark green leaves held in a fan shape that blooms in the spring on a short, pendant to lateral, single flowered inflorescence and carrying a non-resupinate flower.

CAUTION!!!!!!!The first photo is what I feel is the real C subquadrata, notice the square lip without an acute apex and the triangular column that is thicker towards the apex than below matching Schlechter's type description and drawing, the second photo shows what is known commercially in Costa Rica as C subqudrata and the third photo matches Patricia Harding's photo [2008] exactly but she mentions herself [pers comm. 2020] that she feels that this photo really is of a yellow form of C tigrina.
