Oregon: Grant: Malheur National Forest, Starr Ridge; FR 3925, north of road, between spur roads 3925-316 and 3925-946. Elev. 1524 m.
44.208436° N, 118.954408° W,
Habitats various; serpentine rock shelf to the north of road is disintegrating, creating talus slopes of fine gravel above rock shelves; water appears to be pooling on the rock shelves and seeping out at the bottom of the slope, where wet meadow vegetation occurs; no trees inhabit the talus (drought stress?), but many forbs do; the ridgeline above is an ecotone between talus and pine woodland; high diversity area. Minute annual herbs growing in talus; flowers bright white, anthers yellow. Https://oregonflora.org/collections/individual/index.php?occid=4490202.
