Flora of North America North of Mexico--Phase 2

北美植物群项目是一个合作项目， 美国和加拿大的博物馆和大学奋进， 产生一个权威的所有物种的分类清单 北美不人工栽培的维管植物 墨西哥北部。 包括所有的蕨类植物，裸子植物 （针叶树和苏铁）和开花植物，估计有17，000种 两万个物种。 十二卷印刷本和一本计算机化的 数据库将准备，以包含形态学 描述，染色体数目，地理范围，方言 名称，栖息地和物候说明（ 开花和结果），都安排在一个现代分类学 分类系统。 该数据库将作为一个 持续的资源，并将提供方便地访问数据， 广泛的用户。 第二阶段活动包括编辑工作， 物种水平处理的准备和说明， 作者讲习班和数据库管理。 组 在补助期内将受到关注的植物 包括莎草科、豆科 蔷薇科（Rosaceae）。 北美植物群项目综合了 关于北方植物的最新分类信息 墨西哥北部的美洲大陆。 这些信息将是 用于资源管理者，自然资源保护者， 植物的经济和医药用途，以及研究生物学家。 清单将构成基准数据， 可以监测当地和全球环境状况， 它将提供一个植物多样性的摘要， 大陆地区。

The Flora of North America Project is a collaborative endeavor among U.S. and Canadian museums and universities to produce an authoritative taxonomic inventory of all species of vascular plants growing without cultivation in North America north of Mexico. This would include all the ferns, gymnosperms (conifers and cycads), and flowering plants, estimated at 17,000 to 20,000 species. Twelve printed volumes and a computerized database are to be prepared, to contain morphological descriptions, chromosome numbers, geographic range, vernacular names, and habitat and phenological notes (seasonality of flowering and fruiting), all arranged within a modern taxonomic system of classification. The database will be maintained as an ongoing resource and will provide easy access to the data for a wide range of users. Phase two activity includes editorial work, preparation and illustration of species-level treatments, workshops for authors, and management of the database. Groups of plants that will receive attention during the grant period include Cyperaceae (sedge family), Fabaceae (bean family), and Rosaceae (rose family). The Flora of North America project provides a synthesis of up-to-date taxonomic information on the plants of the North American continent north of Mexico. Such information will be of use to resource managers, conservationists, those exploring economic and medicinal uses of plants, and research biologists. The inventory will form the baseline data by which changes in local and global environmental conditions can be monitored, and it will furnish a summary of the plant diversity of this continental region.
