The field names below are not necessarily shown in the order that they appear in downloaded data files. Note that the data contained in Calflora is dynamic, and the database may also change structure periodically to adapt to new needs or processes. . CALFLORA RECORD NUMBERExample: 7245 Unique ID number (integer) for Calflora record. These numbers are revised from time to time as circumscriptions or database maintenance dictate, please be advised not to use them as unique identifiers for taxa unless you are willing to perform maintenance on your data references. (links based on taxon names or ID codes (PLANTS, ADP or ITIS TSN) are probably more stable long-term. CALFLORA TAXON NAMEExample: Abronia villosa S. Watson var. aurita (Abrams) JepsonMax size: 255 (logistically longest: 138 for Pentagramma triangularis ssp. semipallida) Full name of taxon, concatenated from the separate name component fields. Usage and spelling generally follows the Jepson Manual (Hickman 1993). Taxa given partial recognition in the Jepson Manual ( eg. 'plants with fr. < 3mm have been called var. minima') are also included, as are taxa recognized as distinct by the California Native Plant Society in the Inventory of Rare and Endangered Plants of California. We plan to include additional plants discovered or recognized since these publications, with criteria for inclusion currently under development. The list of names originally used in Calflora was provided by Fred Hrusa, California Department of Food and Agriculture. Differs from field taxon in that it includes author citation. TAXONExample: Abronia maritima concatenated from the separate name component fields: Note: A taxon record does not always correspond to unique plant species or end-points of diversity. i.e. Calflora contains separate records for Pentagramma triangularis, Pentagramma triangularis ssp.triangularis, and Pentagramma triangularis ssp. semipallida. If one were tracking biodiversity for an area, it would be wrong to double count both a parent taxon record "Pentagramma triangularis" and a child taxon record (i.e. Pentagramma triangularis ssp. semipallida" as two separate units of biodiversity. See additional discussion under the field description for parent_child. GENUSExample: Abronia SPECIESExample: villosa AUTHOR 1

CATEGORYExample: 3Dicot Values include: Designed to facilitate sorting of records in a phylogenetic order. PARENT/CHILD TAGExample: childMax size: 10 This field tags the record as child, stepchild, or parent. A child is a fully recognized taxon that is included in another taxon within this database. A parent is the taxon within which the child is included. For example,
(A stepchild is a taxon not fully recognized as distinct in the Jepson Manual (Hickman 1993), but included here because it is recognized as distinct by the CNPS or considered possibly distinct by the Jepson Manual treatment author. A taxon from which the stepchild is doubtfully distinct is not identified as a parent.) This tag is intended to facilitate species counts--including both a child and its parent results in an over-count of taxa. PARENT RECORDNUMExample: 345Max size: 4 For children this is the calrecnum of the parent. For stepchildren, this is the calrecnum of the taxon from which the stepchild is possibly distinct. PARENT NAMEExample: Trifolium andersoniiMax size: 42 For children this is the name (genus + species + rank + ssp_var) of the parent. For stepchildren, this is the name of the taxon from which the stepchild is possibly distinct. TREATMENT NOTEExample: optional in Jeps. Taxa not included or not fully recognized in the Jepson Manual (Hickman1993) have a note here explaining inclusion in Calflora. 'Optional in JM' refers to taxa mentioned as possibly distinct in the Jepson Manual. Values include: NATIVEExample: t Each taxon is classed as t (true) for Native or f (false) for Non-Native (Introduced). This data is based mainly on comparison of Fred Hrusa's XWALK designation and the Calflora 'introduced' designation, with individual review of conflicts and gaps. LIFEFORMExample: Perennial Each taxon is classed as one or more of the following:
Transcribed from Lum/Walker codes except that occurrences of 'not specified' were replaced with my interpretation of description in Munz or the Jepson Manual. For taxa included in the CNPS Inventory (1994), this field contains the lifeform descriptor used in that database (some infrequently-used adjectives have been dropped). For taxa not included in either Lum/Walker or the CNPS Inventory, this field contains transcriptions of data from the USDA PLANTS database. All Pteridophytes were reclassified as lifeform 'Fern' on 30 January 2001. All Ericaceae (Monotropoideae) previously marked 'saprophytic' reclassified as 'mycoparasitic' per communication with Garry Wallace (Wallace 1975) on 13 March 2001. US DISTRIBUTIONExample: CA EndemicMax size: 20 Describes distribution beyond California. For non-endemic taxa included in CNPS Inventory (1994), this field contains the non-California portion of the distribution entry from that database: standard 2-letter codes for U.S. states, alsoCOUNTY LIST (County Distributions)Example: ALP ELD HUMList of County regions where this species is, was, or may be present, based on data included in the Calflora Occurrence Database.
PLANT COMMUNITIESExample: m16m17m15 MedwsMax size: 42 List of two-digit codes each preceded by a 'm', no spaces (e.g. 'm13m27m29') Codes m01-m29 correspond to numbers used in Munz68 plant communities list (see Munz68 pp12-18 for descriptions)
LOWER ELEVATION LIMIT IN FEETExample: 3500Max size: 5 Richard Walker's compilation
of elevation limits for Sierran taxa, based on Munz (1968) distribution
descriptions, is the primary source of elevation data presented here. For
taxa not included in Walker's compilation, we present elevation values
from the Jepson Manual (1993), converted to feet. Converted values are
rounded only to the nearest foot to minimize compounding of rounding
errors if users convert all values to meters.
ELEVATION SOURCE & ORIGINAL UNITSExample: Munz (ft.)Max size: 10 Source(s) of elevation data and unit of measure used in the original
data.
Values of 'Rarity' code from CNPS Inventory database (CNPS 2008). Taxa not included in CNPS Inventory are designated 0 (not rare).

The likelihood of a species occurring in wetlands versus non wetlands in California as determined by the U.S. Fish and Wildlife Service. Note that indicator categories do not refer to degrees of wetness. Some obligate wetland species occur in wetlands which are only temporarily or seasonally flooded. Data provided by Andrew Cruz and Buck Reed, U.S. Fish and Wildlife Service, National Wetlands Inventory, October 1997 ( further information). Indicator categories: An asterisk (*) following a regional Indicator identifies tentative assignments based on limited information from which to determine the indicator status.
A positive (+) or negative (-) sign is used with the Facultative
Indicator categories to more specifically define the regional frequency of
occurrence in wetlands. The positive sign indicates a frequency toward the
higher end of the category (more frequently found in wetlands), and a
negative sign indicates a frequency toward the lower end of the category
(less frequently found in wetlands).
Weed status code and URL from the California Invasive Plant Council.
The total count of records in the Calflora Occurrence Database that are unambiguously assignable to this taxon (including synonyms and included sub-taxa).
The
ITIS Taxonomic Serial Number for this taxon.
A single common name for the plant.
Is this record active? When there is a name change,
and several nomenclature authorities agree on the new name,
then Calflora will create a new record for the new name,
and set active = 'f' on the old record.
The mean ultramafic affinity
