  Fred Hrusa's CROSSWALK

This is an extract from the nomenclatural crosswalk compiled by Fred Hrusa. The crosswalk is a database that accounts for the application of names of California plants. For the most part, The Jepson Manual of 1993 is the source of accepted names. The crosswalk is Hrusa's attempt to determine the Jepson name for names occurring in previous literature. In this extract, the "accepted name" forms the first line of each paragraph, with synonyms and misapplications indented beneath it. The abbreviation pointed to by the arrow is the source of the application of the name. Expansions of the abbreviation can be found at the bottom of the page. Notes about the publication of a name, and sometimes other comments, can be found between curly brackets following the name. Links are provided for names that are represented in the Jepson Interchange.

Comments tied to a name can be e-mailed in by clicking on a left-pointing arrow.

For general comments, Fred Hrusa can be contacted by e-mail: FHrusa @
