The Smithsonian Institution has a long history of monographic and floristic work on the plant family Gesneriaceae, one of the largest families of the Lamiales as now circumscribed. Conrad V. Morton worked on the family from the 1930s until his death in 1972. Shortly after Morton’s death, Dr. Laurence E. (Larry) Skog was hired to continue research on Gesneriaceae in the Smithsonian’s Department of Botany, and continues to work on the group since retiring in 2003. In large part due to the work of these two scientists, the United States National Herbarium (US) has grown to have one of the largest and richest collections of Gesneriaceae in the world, with approximately 28,000 specimens and including about 1,000 types. Although the emphasis of the collection is on New World material it includes many specimens from the Old World, with particularly significant holdings of Chinese, Philippine, and Pacific Island material. The department also maintains a small living collection of approximately 300 accessions in its research greenhouses in Suitland, Maryland. ... [Information of the supplier]
The Global Compositae Checklist is a searchable integrated database of nomenclatural and taxonomic information for one of the largest plant families in the world (also known as the Asteraceae). The database is compiled from many contributed datasets and is continually being edited and updated and should be considered a working checklist. Datasets for the Compositae from across the world have been integrated in the Global Compositae Checklist using purpose designed Checklist Integration software (C-INT, Landcare Research, New Zealand). Names are matched using a set of rules and a consensus name is generated with all original data sources linked to that name. In this way no information is lost and the consensus name is a summary of all information from multiple data providers that are in agreement on any given field. Entries are complete to differing levels depending on the data contributed (e.g. only some data sources have type information). Broad distribution data has been included, using the TDWG Geographic Standard although, as this is derived from the data contributed, the distribution is not necessarily comprehensive. Taxonomic concepts are also derived from the data sources, using a system of prioritised ranking where local datasets have more weight that global. ... [Information of the supplier]
This resource gives an overview of the known chromosome numbers, up to now, within the Asteraceae. Through a detailed search mask the chromosome numbers, the taxa investigated, and bibliographic references are accessible. Publications up to and including 2005 are recorded in the resource.

The SOL Genomics Network (SGN) is a clade oriented database dedicated to the biology of the Solanaceae family which includes a large number of closely related and many agronomically important species such as tomato, potato, tobacco, eggplant, pepper, and the ornamental Petunia hybrida. SGN is part of the International Solanaceae Initiative (SOL), which has the long-term goal of creating a network of resources and information to address key questions in plant adaptation and diversification. A key problem of the post-genomic era is the linking of the phenome to the genome, and SGN allows to track and help discover new such linkages. ... [Information of the supplier]
