Michael's Rein Orchid (Platanthera michaelii) Native orchid, endemic in California. Flowers/perianth is green to yellow-green. Lowest petal lip is broad/deltate-ovate. The 2 lower sepals spread outward (and are not reflexed like P. elongata). The 3 upper sepals/petals are concave and point upward. Spur is long at 8-12 mm (but not as long as P. elongata whose spur is 6.5-18 mm). Peak bloom time: June-July.

Piperia is a former genus within the orchid family Orchidaceae that has since been subsumed under Platanthera. Jepson eFlora and all the references below still call it Piperia michaelii, Michael's Rein Orchid
