Aceraceae Tree with deciduous, opposite leaves that are usually simple and palmately lobed but may be pinnately compound. Flowers regular, sometimes perfect, in clusters. Sepals 4-6, petals 4-6 or lacking. Stamens 4-12 (usually 8), pistil 1. Fruit a samara (a winged fruit).Aceraceae Maple Red Maple Aceraceae Maple Big Tooth Maple Aceraceae Maple Box Elder Aceraceae Maple Box Elder Adoxaceae Small, perennial, mat-forming herb with lobed leaves. Erect flower stems topped by a box-like structure with five flowers attached, one on top of box and one on each side. Flowers regular and perfect. Flower structure unique in that the number of sepals, stamens, and other floral parts of the top flower are not the same as those on the side flowers. Fruit a dry berry with 4 or 5 nutlets. The Muskroot Family is also called the Adoxa Family.
Adoxaceae Muskroot
Musk Plant
Agavaceae Leaves usually long and pointed, tipped with spines, margins with spines or fibers, and arranged as a rosette around a stout flower stem which has numerous, often large, showy, fleshy flowers. Flowers usually perfect. Corolla parts in threes. Stamens 6, pistil 1. Fruit three-chambered fleshy or more often dried, firm, almost woody with numerous seeds. The Yucca genus of this family is very common at lower elevations, prairie, and high desert and is quite interesting to study as it is completely dependent on the Pronuba moth (Tegeticula yuccasella) for pollination.Agavaceae Agave Narrow Leaf Yucca Agavaceae Agave Narrow Leaf Yucca Agavaceae Agave Broad Leaf Yucca Agavaceae Agave Narrow Leaf Yucca Alliaceae
Weber's Alliaceae is included in Liliaceae by other botanists. Alsinaceae
Weber's Alsinaceae is included in Caryophyllaceae by other botanists. Anacardiaceae Primarily shrubs and trees, usually compound leaves. Flowers perfect or imperfect, regular, small in terminal clusters. Sepals 3-5, petals 3-5 or lacking. Stamens 5 or 10, pistil 1. Generally fleshy fruits (drupes) with one chamber and one seed. Many, as in the case of Toxicodendron rydbergii, produce Urushiol, an irritant. This family includes several species (Cashew, Pistachio, Mango) of economic importance. The Sumac Family is also called the Cashew Family.Anacardiaceae Sumac
Sumac Anacardiaceae Sumac Sumac Anacardiaceae Sumac Poison Ivy Apiaceae Annual, biennial, or perennial herbs. Leaves usually divided several times. Flowers mostly regular and perfect. Sepals 5 or lacking; petals 5, small. Stamens 5, pistil 1. Fruits large or small, round or long and pendant, horizontal, or vertical. Members of this large and very frequently encountered family often have flat-topped, pancake shaped flower clusters (umbels)sometimes quite small, sometimes eight inches in diameter. Distinctive Parsley smell, especially when foliage or seeds are crushed. Some Parsley Family species in our area are very visible: Ligusticum porteri; some are easily overlooked: Oreoxis alpina; some are deadly: Cicuta maculata."Umbelliferae" is an accepted alternate scientific name for this family and it is used by Stanley Welsh (A Utah Flora).
The Parsley Family is also called the Carrot, Umbel, or Celery Family.

NAMENOTES Asteraceae This is the largest plant family in the United States (~2,400 species) and the world (~23,000 species). The family is made up of shrubs and herbs with inconspicuous to showy flower heads that appear to be one flower but are actually a composite of a number of flowers. Flower heads may be made up of long, narrow, arching ray flowers (Dandelions, Taraxacum spp); or may be made up of short vertical, cylindrical disk flowers (Thistle, Cirsium and other genus spp); or, most commonly, may be made up of both ray and disk flowers (Sneezeweed, Hymenoxys hoopesii). Ray flowers may number from one to several dozen. Disk flowers are often in the many dozens. Fruit an achene, a one-chambered dry, hard fruit varying considerably in size.
"Compositae" is an accepted, but uncommonly used, alternate name for this family. Stanley Welsh (author of A Utah Flora) calls this family "Compositae" not "Asteraceae". The Sunflower Family is also called the Aster, Daisy, or Composite Family.
