Masdevallia datura

One of my favorite Masdevallias, this species from Ecuador has huge flowers on a small plant.  The plant is about 12 cm tall, but the flowers are nearly the same size from the back of the flower to the tip of the tails, and even larger, 15 cm, from tip to tip.  The name, datura, refers to the flowers' resemblance to those of the Moonflower, Datura inoxia, which they do indeed resemble both in color and form.  The plant flowers primarily in the spring, and the flowers have a faint, lily-like fragrance.
