Domain: Eukarya
    Kingdom: Plantae
    Phylum: Magnoliophyta
    Class: Magnoliopsida
    Order: Caryohyllales
    Family: Chenopodiaceae
    Genus: Chenopodium
    Species: Chenopodium ambrosioides

Characteristics that determine why the organism is grouped into each specific category include:

Eukarya: Nuclear envelope with two membranes, membrane bound organelles, true nucleus, and a cytoskeleton     
Plantae: Photosynthetic, share a freshwater algal ancestor, cell walls of cellulose, and express an alternation of generations
Manoliophyta: Angiosperms, seeds are covered, produce flowers and fruits, and have a dominant sporophyte gerneration
Magnoliopsida: Dicotyldedons, vascular bundles usually born in a ring around pith, and most have a primary root system derived from the radical
Caryophyllales: Most of the time stems have concentric rings of xylem and phloem or of vascular bundles, a central protein crystal (unlike most eudicots that have sieve tube plastids with starch grains), and phloem sieve tubes that contain plastids with outer ring of proteinaceous filaments
Chenopodiaceae: Contain pigments called betalains, annual or perennial, monoecious, dioecious, or polygamous, evergreen or deciduous, jointed stems, aromatic bark, flowers are bisexual or unisexual, usually simple leaves that alternate, but are occasionally opposite of eachother
Chenopodium: Goosefoot family, goosefoot refers to the shape of the leaves
Chenopodium ambrosioides:
refers to the plants resemblance to Ambrosia, more commonly known as the ragweeds

Common names:
American Wormseed, Jerusalem parsley, Mexican tea, Sweet pigweed, West Indian Goosefoot, Wormseed Goosefoot, hedge mustard, skunkweed, and Wormseed. Many of these names are either referring to the plant's pungent odor or its ability to fight intestinal worms, for more information on the plants uses in medicine see Medicinal Uses.

To better understand the complex relationships of plants I will next explore the topic of plant phylogenies. Phylogeny refers to the developmental and evolutionary history of an organism. Phylogenies can be put together based on information gathered in numerous ways, but the trees I have chosen to feature were put together based on the exploration of many specific genes within the plant kingdom. It's important to understand that these phylogenies are in flux at the moment and many studies are being done to determine the relationships of plants, especially the Chenopodiaceae family. These phylogenies that I have constructed through my research are subject to change, but represent the most accurate and up to date information.


The phylogenetic tree pictured above is a representation of the Angiosperms as a whole and was constructed based on genetic analysis. I chose to leave out the nonvascular, seedless vascular, and gymnosperms which come before the branching of the angiosperms on the larger tree of life. The Magnoliids were the first to branch followed by the Monocots and then the Eudicots. The Asterids is a clade of the core Eudicots but they branch later in the tree. The order Caryophyllales is one of many branches of the Asterids. The Asterids then breakdown into three families. One of which is Chenopodiaceae, which is broken down further in the phylogenetic tree below. 

The tree above takes the Chenopodiaceae family and breaks it down into the three species based on genetic analysis and depicts its closest relative to be the Amaranthaceae family. The Spinacia genus is mostly closely related to Chenopodium and contains plants such as spinach. The genus Beta is still a part of the Chenopodiaceae family, but not as closely related to the Chenopodium genus. Each genus breaks down even further, but considering there are over 100 members of the Chenopodium genus keep in mind this is a condensed version of a much larger tree.
