Pleurothallis cauliflora Lindl. 1837 SUBGENUS Crocodeilanthe [Rchb.f & Warsc.]Luer 1986 Drawing by Hooker and The Plant Illustration Website

Common Name The Flowering Stem Pleurothallis [refers to the short pedicellate flowers largely engulfed by an inflated floral bract adpressed to the rachis]

Flower Size .12" [3mm]

Found in Ecuador at elevations of 2500 to 3400 meters as a small to medium sized, cold growing epiphyte with fasciculate, stout, erect ramicauls enveloped by a loose tubular sheath near the middle and 2 to 3 loose, imbricating sheaths at the base and carrying a single, apical, erect, coriaceous, broadly elliptical-ovate, obtuse, rounded below and contracted into the slender, petiolate base leaf that blooms in the fall on 1 to 2, stout, more or less secund, 6 to 10" [15 to 25 cm] long including the 1.6 to 2.8" [4 to 7 cm] long peduncle, densely and simultaneously many flowered inflorescence arising through a foliaceous spathe from an annulus set below the abscission layer and has an inflated, expanded floral bract that completely envelopes the pedicel, ovary and much of the flower.

Although the ramicauls are enveloped by large, loose sheaths and similar to P elegans and P galeata this species with its broadly elliptical, obtuse, long petiollate base leaf with the elongate foliaceous spathe is distinctive.
