WORKSHOP DESCRIPTION
This workshop is designed for new users of the second edition of The Jepson Manual. It will provide an introduction to the manual, including an overview of its organization and a summary of print and digital resources that can
be used to enhance the experience of identification. A brief discussion of some of the common changes included in the
second edition will be illustrated with hands-on examples and lab activities in the morning, followed by group keying
of plants in the afternoon. Participants will become familiar with plant characteristics needed for efficient identification
to group, family, or genus, and will gain practical experience by working through keys and common questions as a
group.
The workshop will be indoors, working with fresh plants collected from various field locations. A general familiarity with morphological terms is helpful, but not required; these will be reviewed during the introductory and group
keying sessions. Participants are encouraged to bring their personal copy of the second edition of The Jepson Manual
(print or digital); some print copies will be available to borrow. Participants will receive a dissecting kit and will use a
dissecting microscope to study plants; previous microscope experience is helpful but not necessary.

What is TJM2?
The Jepson Manual: vascular plants of California, Second Edition [or sometimes, TJM2] is
the reference for the flora of California.
What do you use it for?
TJM2 is an all year round field manual to key and identify the vascular plants of California.
Use it all year round - in the field and office!
Check out the inside cover of TJM2. Here you will find a great list of online resources available from the Jepson Flora Project [http://ucjeps.berkeley.edu/jepson_flora_project.html] for a
convenient reference guide. These online resources help make identifying plants fun and fast! This
workshop includes these references, provides examples within TJM2, and provides additional resources for using the TJM2 to key and identify plants of California.
What can’t be keyed using TJM2?
Mosses, lichens, algae, and fungi are not included in the project. But there are really good
resources that will help you identify these organisms in California [Moss eFlora http://ucjeps.berkeley.edu/CA_moss_eflora/], check out the Jepson eFlora and other eFlora tools [http://ucjeps.
berkeley.edu/IJM.html], and the appendix to this handout for references.
What can be keyed using TJM2?
Vascular plants of California! This includes more than 185 plant families of native and naturalized taxa, in eight major clades. These are Ferns, Lycophytes, Gymnosperms, Nympheales, Magnoliids, Ceratophyllales, Eudicots, and Monocots. Check out the Phylogenetic Index [inside back
cover, or online http://ucjeps.berkeley.edu/clademap2.html] to see how the families are arranged
in the second edition.
TJM2 covers native and naturalized taxa of California - cultivated or horticultural taxa,
waifs, urban or agricultural escapes were NOT included in the hardcopy and digital text. The
supplement and Jepson eFlora INCLUDES these waifs, urban or agricultural escapes, and agricultural weeds.
Note: Terrestrial plants in only vegetative condition will not be [easily] keyable using just the
manual. No worries, that’s what online resources are for!
There have been huge changes since the 1993 edition and these are contained in the Second Edition of The Jepson Manual and updated online at the Jepson eFlora. Ongoing botanical
research in the California flora means the work isn’t done! Revisions, updates, and corrections are
posted to the Jepson eFlora [http://ucjeps.berkeley.edu/IJM.html].
This is a brief list - check out the additional references at the end of the handout. *Tip. Always keep a pencil handy to
annotate your TJM2 in the margins or add *digital notes* as you work through a key. There will never be a time when
you regret writing out your complete thoughts in your field manual or a flora. MAKE MARGINALIA!

Quick Guide to TJM2
How is The Jepson Manual, Second Edition organized? And why? Read the Philosophy on pgs 1-2,
and the Conventions pgs 3-11.
Are you looking for a taxon by scientific name or common name and want the page number?
Check out the Index pg 1523-1568. Bold numbers are for the first page of the family or genus
description, and italic numbers are for illustrations.
You can also find clades and families included in TJM2 by the Phylogenetic Index on the back cover,
and online http://ucjeps.berkeley.edu/clademap2.html
Where is Hydrophyllaceae or Lennoaceae in TJM2? You won't find them in the Phylogenetic Index, but
look within the Index on pg 1544 for Hydrophyllaceae and pg 1546 for Lennoaceae. Both families
are now included within Boraginaceae and found on pg 450.
For an online resource that quickly gives an overview of how families and genera are
treated between the 1993 TJM and TJM2 refer to:

Reading the text
Information about how information is presented is included in the Philosophy [pg 1] and the Conventions [3].
What do all those scientific names mean?
Scientific names are information. The point is effective communication in a hierarchical system - and it has to work for written and oral communication for today, for the future, and it has to
be consistent with previous publications. So there are some rules - this is science! But these rules
are fairly easy to remember and even easier to use. The first rule is to give it a try!
The name can help give details about the plants - so look at those binomials in the INDEX and you
will start recognizing some common and descriptive epithets. ramosissima [very branched], angustifolium [narrow leaved], sericea [silky], annuus [annual], brachyloba [short lobed]. Color is helpful
too - viride [green], alba [white], aurianticus [orange], grisea [gray]. Place names can also help,
californica [California], franciscanum [San Francisco], yosemitanum [Yosemite], chilensis [Chile],
vallis-mortae [Death Valley]. Also habitat - insulare [island], cismontana [cismontane], serpentinus
[serpentine], inundata [flooded places], salina [salt springs].
The ending “ii” or “ae” provides information about the person for whom the taxon was named
- Phacelia piersoniae L. O. Williams* [listed on ICPN as a synonym of Phacelia heterophylla var.
virgata pg 494*] was named for Rua Pierson [or Terua Pierson, or Terua P. Williams]. The abbreviated author is given at the end of the scientific name for botanical nomenclature, for animals and
insects you will see a year of publication added at the end and no author abbreviation. In this
example the author is Louis Otho Williams who published the name in 1932 [Williams, L. 1932.
Field and Herbarium Studies, I. Bulletin of the Torrey Botanical Club 59(7):427-429.]. He and Rua
married in 1934 and botanized as a happy team together. *TIP. Spelling does matter! Phacelia
peirsoniana J. T. Howell [pg 498*] was named for Frank Warrington Peirson.
In TJM2 the scientific names of Native California Taxa, naturalized plants and waifs, and uncertain
status taxa are identified by type face. Symbols are used to indicate status:  indicates a native
plant listed by CNPS,   indicate invasive non-native taxa listed by CDFG or CalIPC.
How do you pronounce that name?
When in doubt, sound it out! Pronounce all the syllables. The emphasis is usually on the
second to last syllable. Proper names [people and places] keep their original pronunciation for the
stem word, nuttall - ii, douglas - sii, eastwood-ae, dales-iana, austin-i-ae, trask-i-ae.
The second rule is to BE BOLD! Botanical Latin is a modern technical language practiced and used
by botanists. There are very few ways to mess it up. It always helps to key out loud and practice
saying scientific names. Practice helps with pronunciation and with remembering new plant names!
PRACTICE!
Krascheninnikovia lanata. Winter fat. The genus name is named in honor of Krascheninnikov.
Krasch - en - in - ni - kov - i - a la - na - ta. Or of course, crashin in a cove ee ah.
Asplenium septentrionale. Ah- splee- NEE- um sep- ten- tree- oh- NAH- lee.

Navigating and integrating resources
TJM2 was supported by numerous sponsors, authors [pgs xvii-xxii], illustrators, and editors. The Dedication to James
Hickman, Preface about Willis Linn Jepson [pg xiii] and Acknowledgements [pgs xv-xvi] cover briefly the history of
this epic project. The Jepson Flora Project continues to update these resources, supported by the Friends of the Jepson
Herbarium. About the Jepson Flora Project, and all the handy online resourcess http://ucjeps.berkeley.edu/jepson_flora_project.html
What are some of these resources? And how do updates and changes get made?
What is a stipe? Look on pg 33 of the TJM2 Botanical Glossary pgs 17-34 [http://ucjeps.berkeley.edu/
IJM_glossary.html], which refers you to the illustration on pg 29. But wait! You say to yourself. The TJM2 glossary
only refers to Ferns in the key to Group 3 (pg 74) and family descriptions pgs 113-134. And you are not looking at a
fern, you are looking at stipes in Eriogonum (genus description and keys, pg 1083-1092. Eriogonum diclinum description pg 1096, illustration 1097)! No worries, the TJM2 glossary has been updated to reflect the different usage of this
term for ferns and Polygonaceae in the online Errata for TJM2. Errata for TJM2 is available at http://ucjeps.berkeley.
edu/JM12_errata.html Discover additional errors, issues, additions, or corrections for TJM2? Contact Dr. Tom Rosatti

General approach to Keying with TJM2
Each couplet leads you through a series of increasingly selective choices until you reach an identifying name for your plant specimen. Keys to groups and families use characters that are universal
and easily diagnostic for large groups of plants. The choice between two leads can sometimes
use a singular character that only describes a particular group of California plants. These singular
characters can allow you to key efficiently - in some cases go straight to the family or genus key.
Treatments in TJM2 are meant to be a used as a field guide to vascular plants - and so the keys are
written with characters that are recognizable in the field. This absolutely means YOU WILL NEED
a 10X magnification handlens. Additional characters are described in descriptions [chromosome
counts, molecular studies] that contribute to species delimitation but are impossible to actually use
in the field. *Tip - Read the descriptions for additional detailed information when keying!
TJM2 is written for plants with reproductive parts available. It is not impossible to key out a vegetative terrestrial plant lacking flowers or fruit using TJM2 - but you will need to rely on additional
resources or try again at another time. *Tip. Can’t decide which lead to choose? Try going both ways in the
key! Plant material at hand may not have the necessary flowering AND mature fruiting material required. Read the descriptions for full characteristics. Choose one key lead and follow it to taxon, then go back and pick the other couplet
lead at the point of confusion. See if the resulting identification helps exclude one of the leads.
Read couplets in order [left to right]. Key leads are supposed to present the most obvious and
clear cut character choices first and subtle differences last. *Tip - if you aren’t having success with the key
at a difficult couplet, go back a step and try again. Still confused? Go back to the beginning and try again. It is easy
to skip a couplet or a character and be led astray.
Everything is “gen” [generally]. That is, the keys present characters that are most common, obvious, and most likely to be encountered in the field for that taxon. Exceptions to the general condition are described in the descriptions. Read the descriptions to get a good idea of the common
characteristics for family/genus keys, and look for additional characteristics for species to provide
confirmation of identification. Remember that characters addressed in genus descriptions are not
repeated in species descriptions if generally true. It is not cheating to read ahead!
Unilateral statements in a key are indicated by an Em dash — preceding the trait. These are only
applicable to the lead in which the Em dash is included.
Geographic subdivisions [pg 44] and soil type can help with keying and identification! California
has high numbers of taxa that only occur within the state [native endemics] or are restricted to certain soil types [serpentine or limestone endemics].
Look at the colors! Flowers can change color after pollination, with water stress, during pressing,
and fade from bright red to pale white over a century in the herbarium. *Tip - Take notes, write down
observations, record questions about the plant material and the steps in keying as you proceed through the keys.
Are you looking at a plant specimen that is early or late season? Check the flowering or fruiting
time in the descriptions. Early, late season, or shaded plants can vary from the typical growth
patterns. Vernal pool plants can have seasonally dimorphic leaves. Eryngium vaseyi (pg 183 and
185) has a juvenile set of leaves when submersed in the pool early in the season and a set of adult
leaves later in the season once the pool dries out.

Plant Characteristics Worksheet
On this page, draw the plant specimen you want to identify.
Draw what you see and label with your descriptions
Reproductive structures available? Flowers, fruit available? Label and describe all parts and characteristics. Include
numbers of parts [e.g., #of sepals, #of petals, #of stamens, # of styles]. Record measurements [all measurements are
metric for TJM2] - a ruler is printed on pp. 1570 and included in your dissecting kit. Some characteristics change from
fresh to dried/pressed specimen [e.g., corolla color, leaf texture]. Dissection of parts using your dissection kits will be
helpful [flower, fruit] and required for some taxa. Magnification of parts using a 10X handlens or the dissecting stereomicroscopes will also be helpful or necessary [e.g., hairs!]. Note incomplete or partial specimens, or variation in parts
within a plant. Record all observations and questions!

Keying Notes Worksheet
There are some common diagnostic taxonomic characters that will come up repeatedly in TJM2,
especially in the Key to Groups and Families [Note: Family and genus keys will have additional characters].
Common characteristics for vascular plants in TJM2
Life history: annual or perennial?
Habit: aquatic or terrestrial?
Herb or shrub/tree?
Woody only at base, or woody throughout?
Leaf: simple or compound?

APPENDIX
Want to learn more? Additional references and resources abound!
Please note the references and resources included in this handout are not comprehensive - there are many
additional resources available for specific botanical interests that you may wish to explore further on your own. I tried
to include resources that had both a hardcopy and an online version, please let me know if links are broken or inaccessible due to subscription or paywall issues.
Questions? Comments? Is this handout missing something helpful to keying and identifying plants using TJM2? I
am always looking for useful tips, good resources, and efficient ways to identify plants in California. Let me know your
favorite tip or tough plant puzzle! Email [email protected]
