East Fork of the San Juan River, June 25, 2007.

Having no chlorophyll, Pinedrops make their living as parasites on the roots of conifers in dry forests. These young Pinedrops, growing in a Ponderosa forest, have probably been showing above the forest floor for no more than a week. They will continue their rapid growth and, depending on the moisture available, will attain a height of one to three feet.

"Pterospora" is Greek for "winged seeds". "Andro" is Greek for "male" and "medea" for "genitals".

The plants at left are over two feet tall and probably will grow another eight inches. Flowers at the bottom of the flower stalk open first.

Pinedrops wither brown and remain a strange sight until crushed and dissolved by snow, or they may stand, as in this photograph, into the next growing season.
