Platanthera sparsiflora is a variable species to which Limnorchis ensifolia and L. laxiflora have been referred. Recently, authors have adopted L. ensifolia for a group of plants that have also been referred to L. laxiflora and P. sparsiflora. None of these existing names apply to a recently delineated but related group, here described as the new species P. tescamnis. This species is distinguished by a small column with short rostellum lobes that position the viscidia above the orifice of the spur. The species exhibits ecological preferences that are unique in the group, occurring at relatively low elevations and in comparatively dry habitats in a hot, arid region. It occurs across the Great Basin and Colorado Plateau and bordering areas in California, Nevada, Arizona, Utah, and Colorado.

J. Sheviak %K Platanthera aquilonis %K Platanthera hyperborea %K pollination %XThe North American Platanthera aquilonis Sheviak has long been known to autopollinate. Pollinia rotate forward and downward out of
the anther sacs and contact the stigma. Previous experimental evidence has indicated that this movement is effected by gravity. In addition to the move ment of whole pollinia, flowers are often found in which continuous streams of pollen massulae emanate from anther sacs and seemingly pour down onto the stigma. Experiments with cultivated plants have shown that water droplets
can collect in the centers of flowers of this species. These sometimes draw a sheet of massulae out of an anther sac either onto the surface of the droplet or into its interior. As the droplet evaporates, the massulae are deposited as a continuous layer from the anther sac onto the stigma. It is suggested that in nature dew may function to produce the observed pollen streams.
Spiranthes diluvialis, a species known from widely scattered localities in the western United States, is formally described. It has been confused in the past with a number of other species. Morphological characters and cytological data indicate an origin through hybridization ofS. magnicamporum andS. romanzoffiana.
