Species Info:

This lifeform is found in the Great Plains of North America. The blue color will help identify this lifeform. This lifeform is found in open grasslands or in plains.

Cut leaved germander (Teucrium laciniatum) has flowers that may be pale blue, liliac, or even white.

Teucrium genus (germander or wood sage) is native to most of the world but is especially common in western Eurasia.  There are about 300 herbs and shrubs in this genus.  These are herbs and shrubs with 5-lobed flowers.  There are two upper lobes, two side lobes, and a broad lower lobe.  Since the side lobes are somewhat united with the upper lobes, the flowers can be referred to as two-lipped.  There are seven species and seven subspecies growing in greater North America.

Mint Family (Labiatae = Lamiaceae) contains over 5,000 species of plants of wide distribution. Many of the plants in this family are known for their tastes and smells. Peppermint, Catnip, and Sage are some of the better known species in this family. The square stems of this family are very helpful in field identification. Taking a stem between your fingers, and trying to roll it back and forth can be one of the first tests in trying to identify an unknown plant. As of 1994, there were about 473 species in 70 genera either native to or established in greater North America, including Puerto Rico, the Virgin Islands, Hawaii, and Greenland.

Tubiflora Order of plants is comprised of a large number of  families that are characterized by having tube-like flowers. Several of the families have asymmetrical flowers with various lip and lobe configurations, while others have symmetrical flowers. The convention is to refer to the corolla divisions as lips, and to refer to the extensions at the end of the lips as lobes.

Dicots (Dicotyledoneae Class) are the predominant group of vascular plants on earth. With the exception of the grasses (Monocots) and the Conifers (Gymnosperms), most of the larger plants that one encounters are  Dicots. Dicots are characterized by having a seed with two outer shell coverings. Some of the more primitive Dicots are the typical hardwood trees (oaks, birches, hickories, etc). The more advanced Dicots include many of the Composite Family flowers like the  Dandelion, Aster, Thistles, and Sunflowers. Although many Monocots reach a very high degree of specialization, most botanists feel that the Dicots represent the most advanced group of plants.

Seed plants (Phylum Embryophyta) are generally grouped into one large phylum containing three major classes: the Gymnosperms, the Monocots, and the Dicots. (Some scientists separate the Gymnosperms into a separate phylum and refer to the remaining plants as flowering plants or Angiospermae.)

For North American counts of the number of species in each genus and family, the primary reference has been John T. Kartesz, author of A Synonymized Checklist of the Vascular Flora of the United States, Canada, and Greenland (1994). The geographical scope of his lists include, as part of greater North America, Hawaii, Alaska, Greenland, Puerto Rico, and the Virgin Islands.

Kartesz lists 21,757 species of vascular plants comprising the ferns, gymnosperms and flowering plants as being found in greater North America (including Alaska, Hawaii, Greenland, Puerto Rico and the Virgin Islands).

There are estimates within the scientific world that about half of the listed North American seed plants were originally native with the balance being comprised of Eurasian and tropical plants that have become established.

Plant kingdom contains a large variety of different organisms including mosses, ferns, and seed plants. Most plants manufacture their energy from sunlight and water. Identification of many species is difficult in that most individual plants have characteristics that have variables based on soil moisture, soil chemistry, and sunlight.

Because of the difficulty in learning and identifying different plant groups, specialists have emerged that study only a limited group of plants. These specialists revise the taxonomy and give us detailed descriptions and ranges of the various species.  Their results are published in technical journals and written with highly specialized words that apply to a specific group.

On the other hand, there are the nature publishers. These people and companies undertake the challenging task of trying to provide easy to use pictures and descriptions to identify those species.
