Hi, The Oregon Flora Project has released a few sample pages from the upcoming two volume set of the Oregon Flora. Two of the families of interest to the PBS are the Iridaceae and Papaveraceae family entries for their descriptions and keys to genera such as for example: Iris, Corydalis, and Sisyrinchium native to Oregon (including other genera, as well as nonnatives). Find links here: http://www.oregonflora.org/flora.php Papaveraveae: http://oregonflora.org/flora/… Iridaceae: http://oregonflora.org/flora/Iridaceae_flora.pdf/ The Oregon Flora Project is the first complete flora in 50 years, and the most up-to-date when it comes to current distributions, invasive species, and plant names.
