{"product_id":"southwestern-rare-and-endangered-plants-usda-forest-service-9781511530699","title":"Southwestern Rare and Endangered Plants: Proceedings of the Fourth Conference","description":"Unusual soils, compared to surrounding common soils, act as edaphic habitat islands and often harbor rare plants. These edaphic elements can be disjuncts or endemics. Two rare wild buckwheats from southeastern Arizona that grow on Tertiary lacustrine lakebed deposits have been found to be a disjunct, and an endemic. Eriogonum apachense from the Bylas area is determined to be a disjunct expression of E. heermannii var. argense, a Mojave Desert taxon from northern Arizona and adjacent California and Nevada, not a distinct endemic species. At a historical location of E. apachense near Vail, Arizona, a new species of Eriogonum, also in subgenus Eucycla, was discovered growing on mudstones of the Oligocene Pantano Formation. It was also recently found on outcrops of the Plio-Pleistocene Saint David Formation above the San Pedro River near Fairbank, Arizona.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Usda Forest Service\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1511530693\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781511530699\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/25\/2015\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 140\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.75lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.02h x 8.50w x 0.30d","brand":"Usda Forest Service","offers":[{"title":"Paperback","offer_id":48623063859455,"sku":"9781511530699","price":16.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/southwestern-rare-and-endangered-plants-usda-forest-service-9781511530699","provider":"WR Book House","version":"1.0","type":"link"}
