Asteraceae Family Members  Botanical Name Lookup
Division: Magnoliophyta (Flowering Plants) --- The most diverse plant group worldwide with over 250,000 documented living species.
Most of the essential oils and carrier oils listed on this website come from this group.
 Class: Magnoliopsida --- Commonly Known As "Dicotyledons" --  This class consists of flowering plants (Angiosperms) whose embryo has two or more seed leaves.
  Order: Asterales
   Family: Asteraceae    aka "Compositae"   Commonly Known as "The Aster or Sunflower or Daisy Family"  Pronounced:  ass-ter’-ah-see-ee    
 This family consists of perennial or rarely annual herbs which have entire or serrate leaves and racemose, paniculate, or corymbose heads of flowers that fan out with white, purple, or blue petals. The flowers often have yellow disk corollas. This family contains the "Starworts" or "Michaelmas Daisies" and many other varieties which are native to the temperate zone in the U.S. Also contained here are the "China Asters" which are native to China and Japan and are popular internationally as garden annuals. For a very detailed history of the Aster Family from 400 B.C. to 1900 please see the book by Edward Burgess   For a closer look at the sub-group known as the "Achillea-Complex" (aka Chrysanthemum-Complex) which covers the Genera of Achillea, Artemisia, Matricaria, Santolina, and Tanacetum please see the article: Mining the Essential Oils of the Anthemideae

Species Defined
A species is a group of plants that have all originated from the same form (Genus), that all resemble each other, that all propagate by spreading their own seeds, and that all have the first part of their specie name in common. By convention, specie names consist of 2 parts, the first part always starting with a capital letter and the second part always starting with a lower case letter. In addition, specie names are also written in italics. For example:
Pinus sylvestris     --     "Scotch Pine"
Pinus strobus     --     "White Pine"
Pinus rigida     --     "Pitch Pine"
These are all plants from the same original form or Genus. The genus name in this example is "Pinus".

Plants within the same genus each vary slightly depending on soil conditions, climate, cultivation method, etc. Examples of slight variations include, flowers differing in color, fruit differing in flavor, leaves differing in form, etc. So, Lemon Verbena (Aloysia citrodora) grown in one country may taste slightly different from Lemon Verbena (Aloysia triphylla) grown in another country. The point is, both Lemon Verbena plants are from the same genus (Aloysia) but since they differ slightly due to climate conditions, etc. they each have their own distinct specie name.

For the purposes of aromatherapy, the percentages of oil constituents in a bottle of Lemon Verbena from Aloysia citrodora might only vary slightly from the percentages of oil constituents in a bottle of Lemon Verbena from Aloysia triphylla assuming the same distillation process was used for both.

Or, the oil constituents could quite possibly vary by a sizable amount. Some examples of oils that vary by a large amount depending on the specific species involved would be Rosemary, Thyme, and Eucalyptus, just to name a few.

With this in mind, finding a bottle of "essential oil" in a store that only says "Chamomile" on it without any specific plant specie name should leave a question in your mind. Do they mean German Chamomile (Matricaria recutita), Moroccan Chamomile (Chamaemelum mixtum), or Roman Chamomile (Anthemis nobilis), or Wild Chamomile (Ormenis multicaulis)?   Or perhaps something else?
