The Vascular Plant Database
This is a SPECIFY database containing the label data associated with the vascular plant specimens from Michigan in the Michigan State University Herbarium; such as collector, collection date, locality, and habitat, along with all additional information added as annotations. All name changes are also recorded. Data was entered mostly by student workers and verified by MSU Herbarium staff.

The vascular plant collection is arranged by family according to the system proposed by Cronquist (1981) and we are databasing the collection in numerical order. Consequently, with the exception of the Poaceae, which have not yet been databased, the label data from all the monocotyledons have been entered and the dicotyledons as far as family # 243 – Ericaceae (October 2009).

How to Search the Database
Specify searches (a.k.a. “queries”) work as filters and return records that match the criteria you select.

You can search the database in two ways:
EXPRESS SEARCH: This will be sufficient for most purposes. For example, if you want to query for all the collections in a genus or all the collections from a specific county, then type in the name and hit return.
ADVANCED SEARCH: This allows you to fully customize your search.

The fields that are returned using the queries above are pre-selected. More data is contained in the database than is readily available on-line. If you require any additional data, prefer the data in a different format, or have any other questions or comments concerning this database, please contact Alan Fryday or Alan Prather
