Intellectual Merit: Flowering plants (angiosperms) are the largest (270,000 species), most diverse, and economically most important group of green plants. Understanding the origin, patterns of variation, and relationships among angiosperms is challenging. Despite progress, relationships among major groups remain unclear, as do relationships within major subgroups (e.g., roses and allies). Our multigene and genomics approaches target 12 problematic groups and subgroups; their resolution should clarify the framework for angiosperm phylogeny. We also will develop the first comprehensive non-DNA database for angiosperms and populate it with key morphological features. Together, our approaches will lay groundwork for collaboratively building the tree of all 12,000 genera of angiosperms. Broader Impacts: The angiosperm tree will be useful to comparative biologists including physiologists, ecologists, paleobiologists, and genomicists. The Botany Browser we develop will provide an informatics infrastructure to bring many data resources to users' desktops. The Angiosperm MorphBank will facilitate group diagnosis, analyses of character distributions, and study of fossils. Our interdisciplinary training of postdoctoral fellows and students will emphasize recruitment of minorities. Our website on angiosperm diversity will be valuable to researchers, K-12 teachers, and students. We will construct pages for the Tree of Life Web Project including TreeHouses designed for K-12 students and teachers. A movable museum exhibit highlighting advances in our understanding of plant phylogeny will be distributed to museums represented in our project. Posters detailing the angiosperm tree will be designed and distributed and made available on CD. Additional outreach will be provided through presentations to local public schools.

智力优点：开花植物（血管）是最大的（270,000种），最多样化，最重要的绿色植物群。了解被子植物之间的起源，变异模式和关系是具有挑战性的。尽管取得了进展，但主要群体之间的关系仍然不清楚，主要亚组中的关系（例如玫瑰和盟友）也是如此。我们的多基因和基因组学方法针对12个有问题的群体和亚组。他们的分辨率应阐明被子植物系统发育的框架。我们还将开发第一个用于被子植物的全面非DNA数据库，并以关键的形态特征填充它。我们的方法将为合作建造所有12,000属被子植物的树奠定基础。更广泛的影响：被子植树将对包括生理学家，生态学家，古生物学家和基因组学家在内的比较生物学家有用。我们开发的植物浏览器将提供信息基础架构，以将许多数据资源带给用户桌面。被子植物莫夫班克将促进群体诊断，特征分布的分析和化石研究。我们对博士后研究员的跨学科培训和学生将强调少数民族的招募。我们关于被子植物多样性的网站将对研究人员，K-12老师和学生很有价值。我们将为生命之树网络项目构建页面，包括专为K-12学生和老师设计的树屋。一个可移动的博物馆展示了我们对植物系统发育的理解的进步，将分发给我们项目中代表的博物馆。详细介绍被子植树的海报将经过设计和分发并在CD上提供。将通过向当地公立学校的演讲提供额外的外展活动。
