This lifeform is found east of the Continental Divide in North America. The blue color will help identify this lifeform. This lifeform is found in swamps or very moist ground. This lifeform is common in suitable environments.
Pickerel weed (Pontederia cordata) is found from Nova Scotia to Minnesota and south to Florida and Texas. This plant is found on edges of ponds and streams. Although found in Northern Illinois, perhaps an approximate center of its range, it is apparently not very common there. However, it appears to be more common further south.
Pontederia genus is native to the New World. There are five to eight perennial herbs in this genus. Most of these species are semi-aquatic. The leaves are thick with many parallel veins and they are on long petioles. The numerous blue flowers are in a spike. One species is established in greater North America.
Pickerel weeds (Family Pontederiaceae) are a group of aquatic plants, including many floating species. There are over 30 species in this family arranged in about seven genera. There are 13 species in four different genera now growing in greater North America, including Hawaii, the Virgin Islands and Puerto Rico.
Farinosa Order is a collection of many different small families of such diverse nature that sufficient arguments exist to treat some of them as full orders.
Monocots are a large group of plants usually characterized by having leaves with parallel veins and a seed with a single shell. Most flowers are created with multiples of three. In the older botany texts, the Monocots were considered more primitive than the Dicots. However, many recent authors have placed the Monocots as an offshoot of the primitive Dicots. Here they are placed before the Dicots.
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.
