Manual of the Higher Plants of Oregon was an early flora of plants of Oregon written by Morton Peck.[1]
It was praised for its format, portability, phylogenetic keys, having new species recorded, and completeness of both descriptions of plants and physiographic provinces.[1] The second edition (1961) includes many changes to the first edition (1941) which, according to Peck, is "now decidedly out of date."[2]
