Plant genome databases

International Plant Names Index
The International Plant Names Index (IPNI) is a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names.
USDA Plants Index
Provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories.

Global Plants
JSTOR's Global Plants contains the contributed collections of more than 300 herbaria from around the globe. Herbaria preserve plant type specimens that are used for the study of botany, ecology, and other plant science disciplines. There are nearly two million high-resolution type specimens currently in the Global Plants database, and this number will continue to grow. Researchers and students can also access reference works and primary sources such as collectors' correspondence and diaries, paintings, drawings, and photographs contributed by partners.

Vascular Plant Image Library
This system was developed initially with support from the Texas Higher Education Coordinating Board as part of a digital flora of Texas project. System elements, including entry pages and the image library full text index are machine-generated, with the last update on 2011, so some links may be "bad"
