| Heads
in boldface indicate user options for sorting data. |
| Taxon: |
Subclass,
family, genus, or species name, or general descriptive category (for
example, cheno-am). Most of the scientific names listed in this column
are from A Utah Flora (Welsh
et al. 1987*1); the names of several plants not recorded in A
Utah Flora are from Arizona Flora (Kearney
and Peebles 1960*1). (Some domesticates—for example, Zea
mays—are not described or discussed in either flora.) |
| Common
Name: |
Most
of the names listed in this column are from A Utah Flora (Welsh et al. 1987*1);
the names of several plants not recorded in A Utah Flora are from Arizona Flora (Kearney

| Part: |
Part
of plant described (for example, seed, leaf, achene). |
| General
Description: |
A
general description of the plant part, which may include information
on two- and three-dimensional shapes, surface characteristics, and
other identifying features. |
Photo
Number(s): |
Linked
to specimen photograph(s). |
| Face
View: |
The
basic two-dimensional shape of a specimen as viewed when the specimen
rests naturally on a flat surface. Also recorded in this column is
information on characteristic features that may be visible in this
view (for example, blossom scars). The following shape categories
are used: |
| |
circular: |
round,
with all diameters equal |
| |
semicircular: |
half
of a circle |
| |
elliptic/oval/lens-shaped: |
not
round; some diameters longer than others, but opposite ends have equal
diameters |
| |
ovate: |
egg-shaped,
with one end broader than the other end |
| |
quadrangular/rectangular/angular: |
having
four or more angles, often with parallel sides, but not hexagonal |
| |
hexagonal: |
angular,
with six equal angles and six flat sides |
| |
triangular/wedge-shaped: |
a polygon
having three distinct side |
| |
variable: |
often
used when an item is fragmentary |
| Cross
Section: |
The
two-dimensional shape of a specimen in cross (transverse) section.
Also recorded in this column is information on characteristic features
that may be visible in this view (for example, interior texture).
The same shape categories used for "Face View" are used for "Cross
Section." |
| Size
Class: |
Three
general size categories, based on the greatest dimension measured.
Some taxa are represented by specimens whose sizes are variable; in
these cases, more than one size class is listed or the size class
is described as "variable." The size classes are as follows: |
| |
small: |
less
than or equal to 1.5 mm |
| |
medium: |
greater
than 1.5 mm, less than 3.0 mm |
| |
large: |
equal
to or greater than 3.0 mm |
| Length: |
When
specimen is in face view, length is measured in metric units along
the greatest dimension. |
| Width: |
When
specimen is in face view, width is measured in metric units at right
angles to the length, at the point of maximum width. |
| Thickness: |
When
specimen is in face view, thickness is measured in metric units from
the ventral (front) to the dorsal (back) surfaces. |
| Surface
Characteristics: |
Description
of selected surficial traits, including texture. |
| Comments: |
Additional
information relevant to the identification of the plant part in question. |
