It grows in coniferous forests and chaparral in deep sandy substrates.

The basal leaves are narrow and almost grasslike, measuring up to 16 centimeters long and no more than 2 wide.

The upper part of the stem is a spikelike inflorescence of up to 100 small flowers.

The flower can be distinguished from that of P. unalascensis by its shorter spur relative to its lip.
