本文总结了美国地质调查局和美国国家博物馆在美国西部几个地方收藏的精选植物化石物种。这并不是对任何一个植物区系的完全修订，但许多新的组合被提出，因为他们相信它们表达了所涉及的物种的更准确的分类配置。在华盛顿州斯波坎的拉塔组和科罗拉多州克里埃德的克里德组描述了7个新种。
This paper summarizes a study of selected species of fossil plants in the collections of the United States Geological Survey and the United States National Museum from several localities in the western United States. It is not a complete revision of any one flora , but many new combinations are proposed in the belief that they express a more accurate taxonomic disposition of the species involved. Seven new species are described from the Latah formation at Spokane, Wash., and one from the Creede formation at Creede, Colo.
