正在审查的这本书所涉及的太平洋地区对地理分布学者和分类学家来说是很有兴趣的。该地区特有的属和种特别丰富，加利福尼亚尤其如此。然而，总的来说，太平洋国家与东亚的植物群表现出有趣的地理联系，这些联系的起源可能太近，不能用来支持任何大陆漂移的假设，但应被视为生态条件相似和传播媒介效率高的证据，也许不排除人类本身。因此，石蜡属植物Leptarrhena pyrolifolia原产于美洲西北部的沿海地区和东亚。同样，pecantia属包括五种，其中三种是太平洋国家特有的，而其他两种是日本本土的。但是，植物群的主要利益在于该地区的特有植物。其中一些是英国园艺学家所熟悉的，如Romneya Coulteri， Eschscholtzia属和lewis属。在蓼科中，单型属Gilmania、Nemacaulis和Hollisteria都是加州特有的，而在已知的150种蓼属中，有80种在太平洋国家发现，其中许多是当地特有的。天竺葵科的特有种有35种，分属Sedella属、Budleya属、Stylophyllum属、Hasseanthus属和Gormania属。在十字花科中，大部分的柱头科、链花科和茎花科都是特有种。蔷薇区也有大量的地方性植物，特别是在Horskelia属（19种）和Ivesia属（17种）。在豆科中，在这方面表现突出的属有Lupinus属，其中58种可能是地方性的；Hosackia属，其中39种大部分是地方性的；Astragalus属有137种，其中83种可能是地方性的。太平洋各州图画集：华盛顿、俄勒冈和加利福尼亚。Leroy Abrams著。一共4卷。第二卷：蓼科到菊科，荞麦到菊科。Pp. viii + 635。（加州斯坦福大学：斯坦福大学出版社；伦敦：牛津大学出版社，1944年）45 s。6 d。网。
THE region of the Pacific States with which the book under review deals is of great interest to the student of geographical distribution and the taxonomist. The area is peculiarly rich in endemic genera and species, and this is especially true of California. The Pacific States show interesting geographical connexions with the flora of Eastern Asia in genera, however, which are probably too recent in origin to be adduced in support of any hypothesis of continental drift, but are to be regarded rather as evidence of the similarity of ecological conditions and the high efficiency of dispersal agents, not perhaps excluding man himself. Thus the saxifragaceous species Leptarrhena pyrolifolia is native both to the coastal regions of north-west America and to eastern Asia. Again, the genus Pectiantia comprises five species of which three are endemic to the Pacific States, whereas the other two are natives of Japan. But it is in the endemics of the region that the chief interest of the flora rests. Some of these, such as Romneya Coulteri, the genera Eschscholtzia and Lewisia, are familiar to British horticulturists. In the family Polygonaceae the monotypic genera Gilmania, Nemacaulis and Hollisteria are all endemic to California while of the 150 known species of Eriogonum 80 are found in the Pacific States, many of them endemic. In the Crassulaceæ there are some 35 endemic species belonging to the genera Sedella, Budleya, Stylophyllum, Hasseanthus and Gormania. In the Cruciferse most of the species of Thelypodium, Streptanthus and Caulanthus are endemic. The Rosacese, too, provide a large number of endemics, particularly in the genera Horskelia (19 spp.) and Ivesia (17 spp.). In the Leguminosse the outstanding genera in this respect are Lupinus, of which 58 species are probably endemic, Hosackia, of which most of the 39 species are endemic, while Astragalus is represented by 137 species of which 83 are probably endemic.Illustrated Flora of the Pacific StatesWashington, Oregon and California.
