"Pleurothallis tinajillensis is most similar to P. ruberrima but it is distinguished by its smaller plants, up to 9.2" [23 cm] tall (vs. 14" [35 cm]), concave, centrally channeled, suffused with purple at the abaxial surface of the leaf (vs. convex, sulcate, green at the abaxial surface of the leaf ), shorter pedicel (.48" [12 mm] vs. .8 to 2.4" [20 to 60 mm] long), minutely pubescent sepals and petals (vs. glabrous), shorter dorsal sepal (.468" [11.7] vs. .6 to .92" [15 to 23 mm] long), extended horizontally petals (vs. reflexed), pulvinate, apiculate, basally truncate lip (vs. convex, broadly obtuse to rounded, basally subcordate), and whitish, complanate column (vs. green and white or purple, ancipitous) with a longer rostellum."
