Lewisiopsis tweedyi is a flowering plant and sole species in genus Lewisiopsis.[1][2] The species, formerly known as Cistanthe tweedyi and Lewisia tweedyi,[3] is now classified in the family Montiaceae. The plant is known by the common names Tweedy's pussypaws, Tweedy's lewisia, or Tweedy's bitterroot. It is endemic to western North America in north-central Washington and adjacent British Columbia. It commonly grows on well-drained slopes often on rocky slopes or in rock crevices from low elevation ponderosa pine sites up to the drier part of the Grand Fir zone of the North Cascades.[4] The flowers usually have a coral, apricot, or pink color.
