Species Info:

This lifeform is found in Europe. This lifeform is widespread in North America. This lifeform is found in Mexico. The white color will help identify this lifeform. This lifeform is widespread, but not common.

Pokeberry or pokeweed (Phytolacca americana) is found from Maine to Minnesota and south to Missouri and Texas. Note the red stems and red stalks, white flowers and purple berries. This species is often found growing along farm fences and in abandoned farm fields.

Phytolaca genus (Pokeweed) is found worldwide in most temperate and semi-tropical regions.  There are about 35 herbs, tropical shrubs, and tropical trees in this genus.  The simple leaves are usually both entire and alternate.  The small flowers are usually  in terminal racemes.  However, further growth of the stem will turn some of these terminal racemes into racemes located opposite leaves.  There are six species and two subspecies growing n greater North America.

Pokeweed Family (Phytolaccaceae) contains about 125 species  organized into seventeen different genera. This family had eight genera with a total of 15 species growing in greater North America as of 1994.

Centrosperm (Centrospermae) order is a large order composed of  several families.

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.
