Deerfoot plant (Achlys triphylla), is found along the coast of British Columbia to northwest California, and also in the Cascade Mountains of Washington and Oregon. This perennial herb has a preference for moist forests. There are three toothed leaflets.

The Achlys genus is represented in North America by two western species.

Barberry Family (Berberidaceae) is found widely in North America and widely in western South America. This family also is found in SE Brazil and NE Argentina. In the Old World this family is found from Europe and northern Africa east to most of the Orient and south into SE Asia. This is a small family of over 500 species. There are about 15 genera in this family. This family is well-represented in the Pacific Coast States of North America. There are 35 species in ten genera established in greater North America.

The family consists of perennial herbs and shrubs with alternate or basal leaves. The leaves may be simple or compound. The flowers are bisexual.

Ranales Order has been broken down into nineteen different families. The water lilies, buttercups, magnolias, and other groups are included in this order. Large pretty flowers seem to be a common characteristic of this order.

The families in this order are in the process of a major re-location. The water lily family (Nymphaeaceae) appears to be an ancient family of plants, and its proper place is open to question. The hornwort (Ceratophyllaceae) family also appears to be a very ancient family, and probably does not belong here either.

Furthermore, the magnolia family (Magnoliaceae) and the buttercup family (Ranunculaceae)are not as closely related to each other as previously presumed, and that is an incentive to further dividing this order.

Until this organization is finalized, we are temporarily retaining this older order.

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 (Aster) 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.
