Hypopitys monotropa) resemble their cousins, the ghost pipes (M. uniflora), but typically sport warmer hues and bear multiple flowers per stem. Pinesaps exhibit significant seasonal color variation, ranging from sallowest yellow in early summer to waxy vermilion as the season progresses.  As the stem unfurls, all the flowers face the same direction and eventually point upward as it matures.  In this form, the stem and seed capsules dry and persist into the coming year, providing a clue as to the whereabouts of this elusive perennial.

Pinesaps are irregularly distributed throughout North America, Europe, and Asia.  In the Pacific Northwest, look for them in conifer woodlands in deep shade on bare soil where little else grows.  Stems appear both singly and in large clumps.
