Piperia candida Rand.Morgan & Ackerman, syn. Platanthera ephemerantha R.M.Bateman, is known as the white flower rein orchid. It is native to western North America from Alaska to the San Francisco Bay Area, where it grows in coniferous forests and other habitat in coastal and inland mountain ranges within 100 miles of the coast. The flowers are sweetly fragrant, and are whiter than those of other Piperia, but sometimes contain some green veining or margins. Photos from Aaron Arthur.
