Psychilis macconnelliae Sauleda (1988), a plant with a pure white lip that is not an alba form, from St. Croix Virgin Islands

One of the defining characteristics of Psy. macconnelliae is its large pink lip.  This particular plant is notable for having a pure white lip.   The plant is not an alba form since you can see it can produce pink pigments by the color of the column of the flower.  It is from the island of St. Croix, where there are large populations of this orchid growing near the seaside.  Generally, in Psychilis species one can see a degree of intraspecific variation in color of the flowers.  But the only other plants with a pure white lip I have seen are the alba forms of Psy, krugii.   For a view of the usual color of the flowers of Psy. macconelliae, use the following link:
