English: Flora of the Pacific Northwest, 1st Edition in the right upper and two later prints to the left, one very field worn. By Charles Leo Hitchcock, Arthur Cronquist, Marion Ownbey, and J. W. Thompson. By most standards this book is extremely outdated with almost half of the species names and families having changed, and most states are trying to put forth their own floras but British Columbia is the only region so far to publish a newer flora.
