| 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). |

| 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.

| 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. |

| 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. |

| 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.

| Cactaceae |
Perennial succulent or herbaceous. Distinctive with fleshy flattened, cylindric, or globose stems; leaves modified to be needle-like spines; areoles give rise to tiny sharp hairs, spines, branches, or flowers. Flowers perfect, regular, often bright and large with many overlapping petals and sepals. Numerous attractive stamens, 1 often massive style. Fruit (often edible and choice) is a dry or fleshy many-seeded berry. Identification of species often based on vegetative rather than floral features and often difficult because plants hybridize. Several species of several genera are quite common at lower altitudes. |

| Cupressaceae |
Ancient family. Shrubs or trees commonly resinous and aromatic. Leaves are evergreen, overlapping scale-like, or needle-like. Male cones are small, female cones with 1 to several seeds are much larger and dry or fleshy at maturity. Rocky Mountain juniper (Juniperus scopulorum) is widespread through the Rockies. Junipers are commonly and incorrectly called "Cedars". True Cedars, the genus Cedrus, are actually in the Pine Family. Cedar fence posts, cedar chests, and cedar firewood are all actually Juniper.
Sometimes also called Cedar Family but not related to cedars.

| Ericaceae |
Mostly small shrubs with evergreen or deciduous, sometimes leathery leaves. Flowers perfect, regular, in terminal clusters. 4 or 5 petals and sepals, 8- 10 stamens, 1 pistil. Fruit a capsule or berry. Several species are very common and very well known: Kinnikinick (Arctostaphylos uva-ursi) and Blueberry (Vaccinium spp). the latter of which rarely produces fruit. The Heath Family is found in mountain regions around the world but we have just a few species in our mid-Rockies tundra, perhaps because of the arid conditions and low acidity. |
