Platanthera colemanii is a rare species of
It grows erect to about half a meter in maximum height. The basal leaves are narrow and almost grasslike, measuring up to 16 centimeters long and no more than 2 wide. Leaves higher on the stem are much reduced. The upper part of the stem is a spikelike inflorescence of up to 100 small flowers. The unscented translucent green flowers have curved sepals and sickle-shaped, curving petals a few millimeters in length. The flower can be distinguished from that of P. unalascensis by its shorter spur relative to its lip.[1]
There are about 19 known occurrences, several of which are within Yosemite National Park.[1] Other occurrences are in unprotected forested lands and may be vulnerable to disturbance from logging operations.[1]
