Where Do You Start?????





Become observers of
nature – teach yourself
As a child we learn
patterns
Plants have patterns
Look for signs
Plants have distinctive
traits
Look for Signs
Physical Features







Eye color
Height
Hair color
Narrow face
Etc, etc
Canis lupus
familiaris
Repetitious patterns
Pattern Shows Relationships

2 – 4 – 6 – 8 – 10 etc

Matching games

Puzzles

Look for similarities between plants


The are easier to learn than some other organisms
Animals much more difficult
Similarities Show Kinship
Salvia azurea
Salvia greggii
Salvias are in the Mint (Lamiacae) Family
Leaf Types
All Mints have
opposite leaf
arrangement
Describe the Stem

Stem shape





Square
Round
Stem habit


Skull cap
Zigzag
Twisted
All Mints have
square stems
Describe the
leaf stem?
Catnip
Describe the Petiole


The leaf stem
Look where attached to
stem



Stipules, other???
Look where leaf
blade attached
See dots, tiny
leaves, glands,
etc???
Describe the Flower




Number of flower petals
& their shape
Describe the calyx
 how many sepals
Number and shape of
pistil & stamens
Position/shape of flower
parts
Imperfect, Dioecious Flowers
Female
Male
Describe Seed or Fruit







Here’s where it can be
tricky
Find the calyx – look inside
Find the flower base
Shape, color, cluster
Fleshy or dry capsule
Etc, etc, etc
The most specific &
unique part of any plant
description
Fruit & Seed Types
Mint Family Flowers





A tube inside a tube
Calyx - fused sepals
Fused flower petals
Flower – lip and hood
Stamens often
extended
Mint Family Seeds


Usually 4
Occasionally 2
Descriptions = Names






All these details make the name
Indicate relationships
Lead to ranking
And more
Sounds complicated…..
We need a system for all this!
Systematic Botany





Identify, classify &
name
A standard system
Hierarchy
Began with Carl
Linné (Linnaeus)
Original developed
from 1735 - 1753
The Ranks – or Hierarchy




What are the ranks?
King David Come Out For
God’s Sake
Each rank can have a
“sub” set
Or a “super” set








Ranking shows
relationships

Kingdom
Division
Class
Order
Family
Genus
Specific epithet
Species name
= G + S + botanist’s name
What’s In A Name


Honorary – Franklinia alatamaha
Specific





May seem backward



Colors - rubra = red
Place - alabamense = named in Alabama
Shape – angustifolius = narrow leaf
Etc, etc

Backyard Botany

Confused?

It’s really not as complicated as you thought


Just use your power of observation


Learn one or two families to start
Look for patterns and describe plant parts
