Pinesap
Monotropa hypopitys
Heather family (Ericaceae)

As the range map shows, this is an uncommon plant in Colorado, but it is quite a memorable find. The plant is a parasite living off fungi which in turn are saprophytes living off dead organic material or they are parasites living off live plants. "Monotropa" is from the Greek "monos," "single," and "tropos," "a turn," meaning "turned or directed to one side," alluding to the one-sided ." Hypopitys means "under pines."

Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.

capsule -- a type of simple, dry fruit produced by many species of flowering plants. In most cases the capsule splits apart to release seeds.

fruit -- any seed-bearing structure in flowering plants. It is formed from the ovary after flowering.
