Distribution of Helianthus samples in Texas herbaria
This page is an example of a mapping system for tracking coverage of
Texas counties by in-state herbarium collections. The selectable items
below display a map of the state with counties highlighted to indicate
that an herbarium within the state has a sample of that
Helianthus species in its collection. At present, the
collections of the following herbaria are in the database:
If multiple herbaria have specimens for a given species in a given county,
the above list represents the order of precedence, i.e., UT's color will
always be shown if their collection covers a county, then TAMU-Tracy's if
UT is not present, then BRIT, etc.

- TAMU S.M. Tracy Herbarium
- TAMU Department of Biology
- SWTSU Department of Biology
- SHSU S.R. Warner Herbarium
- UT El Paso Centennial Museum Herbarium
Naming is according to Hatch et. al.'s A Checklist of the Vascular
Plants of Texas (1990). The map of the state was taken from the Texas
Department of Transportation.
A clickable diversity
map for genus Helianthus is also available.
