Supplementary Help for the CCH Search Page

Scientific name

Enter a genus, genus species, or genus species infraspecific name combination. This field in not case sensitive.

  • Do not include authors.
  • When searching for a infraspecific taxon, the rank should be omitted. 'Rosa woodsii subsp. gratissima' will be searched in the database as 'Rosa woodsii gratissima'.
  • Searches will search both the accepted names and synonyms in the ICPN for the entered phrase, unless the search exact option is checked.
  • Searching by family is not supported.
  • Searching for an incomplete second value is supported. A search of Rosa wood' will produce the same number or more results as 'Rosa woodsii'. The difference between the two results is dependent on the number of similarly spelled names or synonyms in the database.
  • Searching with the wildcard '*' is supported. 'Art* cal' with a space before the species will return 'Artmisia californica' specimens.
  • Wildcards cannot be used in conjunction with searching synonyms. Wildcards only result in a search of the current name only.
  • Searching for statements consisting of four or more elements is not supported. For example: 'Rosa woodsii subsp. gratissima var. glabrata' or 'Rosa woodsii gratissima glabrata'.

Locality

Enter single words or complex phrases. The database will search for that exact pattern anywhere in the locality field. Locality information may have a wide variety of spellings or usages for the same place may be encountered. Users should not expect to retrieve the data for all specimens collected from Yosemite National Park by searching for "Yosemite". Results will be returned only if all the words are found. If the search box is filled with a quoted 2 or 3 word phrase, only records containing that exact phrase will be returned.

Nativity

Jepson eFlora Nativity status for the accepted name.

Life Form

Jepson eFlora life form character from the taxon description for the accepted name.

County

The standardized California county from the label. Typos and misspellings are corrected in CCH1. Note that during the history of botanical collection in California, county boundaries have been altered several times. If the county does not appear on the label it has either been entered as "unknown" or secondarily determined by a data enterer or user.

County Mismatch

Check this to find specimens with georeferences that do not map to the label county name.

Source

Herbarium code that houses the specimen.

Elevation

If you want to search within an elevation range, fill out both the Upper and the Lower field. On the detail page the elevation in feet or meters (units indicated) of the collection site. Elevation may be determined by instrument, map, or estimation. Accuracy should not be relied upon. For the primary result set, all elevations are displayed as meters.

orange color-coded flags

If the results contain a specimen with an elevation higher than the highest elevation point for the county listed on the label, the elevation field will be orange flagged. Read more ... .

Collector

Only the last name of the collector can be reliably used for searching and sorting. Although any phrase can be entered, more characters will yield fewer results. This field is not case sensitive.

Collector number

The collector number is the number used by the collector to index the specimen. Collector numbers have a variety of formats. For the purposes of searching and sorting, the collector number is assumed to contain an alphanumeric prefix followed by a numeric stem followed by an alphanumeric suffix, of which only the stem is pertinent.

Collection Date

The date is the date or date range on which the specimen was collected. It is stored in the database both as it occurs on the label, and as early and late Julian dates. The Julian dates, which are used for searches, accommodate date ranges. Searches for specific dates (e.g., June 6 1946), will also retrieve specimen data with a date range that includes the specific date (e.g., Jun 1946 or 1946). The date on the detail display is formatted as in the database. The date in the primary result set is formatted consistently: month day year.
