MID

Common Name The Ornate Pleurothallis

Flower Size 1/2" [1.25 cm]

Found in Mexico, Guatemala and El Salvador as a mini-miniature sized, cool to cold growing epiphyte at elevations of 1500 to 2500 meters with erect ramicauls enveloped by 2 basal sheaths and carrying a single apical, erect, coriaceous leaf that blooms on a apical, single successive flowered, 2" [4 to 5 cm] long, fractiflex inflorescence that holds the successive opening, single flowers amid or just above the leaves occuring in the winter through mid summer. Cool temperatures, shade, and high humidity as well as mounting on tree fern, and good air movement assure a happy plant.

For years this species has been confused with P schiedei and P villosa which are synomonous, with P villosa taking precedence, as they do not have lamellae, only long pubescence within the flower so neither can be P ornata. Knowles & Westcott described P villosa as a plant 4" high, a flexuous scape and at each bend bearing a wooly and purple spotted flower. No mention of appendages or lamellae which most modern references show as P schiedei but are actually P ornata. Rchb.f in his description of P schiedei states that it is a wooly flower which would eliminate it as a candidate for what we now know as P ornata as well. Rchb.f described P ornata as having short ramicauls and the flower with conspicuous, unique, clavate appendages on the sepal margins.
