Flower Size .04" [1 mm]

Found in Suchitepequez departemnt of Guatemala near Mozatenanque as mini-miniature sized, hot growing epiphyte with an erect ramicaul enveloped by a tubular sheath and carrying a single, apical, erect, coriaceous, elliptic, subacute, cuneate below into the subsessile base leaf that blooms in the winter on an erect, arising laterally from the ramicaul, subcongested, filiform, to 4.8" [12 cm] long including the .72 to 1" [1.8 to 2.5 cm] long peduncle, successively few to many flowered inflorescence with oblique, acute, much shorter than the pedicel floral bracts.

"Distinguished by the minute, shortly repent habit and long peduncles that far surpass the tiny, elliptical leaves. The flowers are produced successively in a long-pedicellate raceme. The simple flowers are similar to P jungermannioides and P minimiflora the other 2 [at the time] species with the smallest flowers in the orchid family. The lip of P bernoullii is ovate, concave, obtuse and shorter than the sepals. The lips of the other two are ovate, narrowed into an acute tip and not concave." Luer 2000
