Choose 'ICN portal' on the main menu, enter Lactuca in the 'Search Taxa' box and select the taxon of interest. Covered subjects include a general species description, synonymy information, images, specimens and distributional and ecological data.

Euro + Med PlantBase

Euro + Med PlantBase

Euro + Med Plantbase integrates and critically evaluates information from Flora Europaea, Med-Checklist, the Flora of Macaronesia, and from regional and national floras and checklists from the area as well as additional taxonomic and floristic literature

GRIN Taxonomy for Plants

GRIN Taxonomy for Plants

Taxonomic information platform provided by the Germplasm Resources Information Network (GRIN) of the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA). Choose 'Plant Germplasm' on the main menu, followed by 'Search GRIN' and 'Taxonomic Queries' on the following pages, respectively. Selecting 'Simple Queries' and entering Lactuca as search criterion then lists nearly 100 species names for which data on taxonomy, synonymy, economic importance and distributional range are presented. Additionally, it is indicated whether specimens are included in the National Plant Germplasm System (NPGS), while also literature references and links to images and other web resources are given.

International Plant Name Index (IPNI)

International Plant Name Index (IPNI)

Database developed through collaboration between the Royal Botanic Gardens, Kew, the Harvard University Herbaria and the Australian National Herbarium. Choosing 'Search Plant Names' on the main menu and entering Lactuca in the 'Genus' box reveals over 700 records with plant names, including species and lower taxonomic levels. Data are provided about plant names and their literature source, synonyms and basionyms, while also concise distributional information is given.

Mansfeld's World Database of Agriculture and Horticultural Crops

Mansfeld's World Database of Agriculture and Horticultural Crops

On-line crop plant species database developed at the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK). Entering Lactuca in the 'Search' box presents over 80 plant names with information about nomenclature and synonymy, common names in different languages, spontaneous distribution, regions of cultivation and uses. In addition, images, references, ancestral species, and notes on the phylogeny, variation and history are provided.

NCBI Taxonomy Browser

NCBI Taxonomy Browser

Curated classification and nomenclature for organisms that have molecular data in the databases of the National Center for Biotechnology Information (NCBI). Entering Lactuca in the 'Search for' box presents nearly 30 records with information about plant names, synonymy and phylogenetic lineages, while access is provided to available data on genes, proteins and sequences.

The Plant List

The Plant List

A working list of all known plant species. It aims to be comprehensive for species of Vascular plant (flowering plants, conifers, ferns and their allies) and of Bryophytes (mosses and liverworts).

Tropicos

Tropicos

Botanical information system of the Missouri Botanical Garden. Entering Lactuca in the 'Quick Name Search' box lists over 400 records with information on plant names, synonymy, specimens, chromosome number, distribution and use. In addition, images and literature references are provided.
