Common Name The Second Pale Yellow Pleurothallis

Flower Size .24” [6 mm]

Found in Brazil without locality as a mini-miniature sized, caespitose epiphyte with erect, stout, short ramicauls enveloped by 2 evanescent sheaths and carrying a single, apical, erect, thickly coriaceous, spathulte-elliptical, acute to subacute, minutely tridenticulate, cuneate below into the petiolate base leaf that blooms in the late summer and early fall on successively 1 to several, arising through an anulus, shorter than the leaf, erect to suberect, peduncle [5 to 10 mm] long, rachis inconspicuous, successively 1 to 2 flwoered inflorscence with long, thin floral bracts.

"P deuteroluteola resembles P guarujaensis in habit, floral color and shape of floral segments, especially sepals and lip. In P deuteroluteola, flowers are smaller, sometimes about half the size of those in P guarujaensis (in the latter, sepals are 4.5–8.0 mm × 1.50–2.25 mm, and petals 3.5–4.0 mm × 1.00–1.25 mm). The inflorescence produces two flowers that open in succession, sepals are 3-veined, petals are obtuse, and the minute, lateral lobules of the lip are glabrous. In P guarujaensis, inflorescence is single-flowered, sepals are 5-veined (the laterals sometimes are 4-veined), petals are acuminate, and lateral lobules of the lip are minutely pubescent or densely papillose and more prominent than in P deuteroluteola. At the base of the lip of both species, a pair of minute lobules are found, a lobule on each angle." Toscano 2018
