Flower Identification
Blue Mist Flower, Eupatorium coelestinum
This Blue Mist flower was in the Christmas Rocks Nature Preserve which is a forest (and this was in the underbrush of the forest). This flower is identified because it has leaves in pairs that are triangular, with a long stalk that can be one to three feet high. It blooms in late summer to fall so I was there at the perfect time over Labor Day weekend! The flowers of this plant are called disk flowers and they are very attractive to butterflies (https://gnps.org/plants/blue-mistflower-wild-ageratum-conoclinium-coelestinum-syn-eupatorium-coelestinum/ )
Tall Coneflower, Rudbeckia laciniata
Oh my goodness these types of flowers are a struggle for me to identify, but what clued me into the identity of this flower was not only its height, but also the greenish-yellow disk. The flower heads can be 2.5-4 inches wide and have 6-8 drooping rays. The lower leaves are pinnately divided into anywhere from 3-7 leaflets that are irregularly lobed. I found this flower at Three Creeks Metro Park right by one of the ponds amongst many other small shrubs and other wild flowers. These flowers attract birds as pollinators and the lower leaves were boiled for greens by the Cherokees (https://www.wildflower.org/plants/result.php?id_plant=rula3)
White Snakeroot, Eupatorium rugosum
This flower was also found at Three Creeks Metropark right by a pond amongst other wildflowers, trubs, and trees. The lower leaves were broad and egg-shaped and become pointed at the end. The flowers are bright white and are in heads that can be 1-5′ high. When the ovary ripens into the fruit, it can be seen that it is an achene fruit! A not so fun fact is that this plant is HIGHLY toxic to humans and can even be fatal if ingested (https://plants.ces.ncsu.edu/plants/eupatorium-rugosum/)
Spotted Touch-Me-Not, Impatiens capensis
WHAT A GREAT NAME!!! I found this flower at Three Creeks Metro Park by a pond with many other wildflowers, shrubs, and trees. These flowers are orange with brown spots and are about 1 inch long and dangle from a long stalk. The egg-shaped leaves are coarsely-toothed. The fruit is a plump pod that actually EXPLODES when it is ripe! The stem is succulent and 2-5 feet high. It grows in moist places (like by a pond) and blooms summer and early fall. The plant attracts birds, hummingbirds, and wildflowers and the stem juice is said to relieve poison ivy itches.
Flower Analysis
This flower was found here (location and habitat/environment): in a planter near the faculty club!
Common name: Common Zinnia Scientific name: Zinnia elegans
Corolla: number of petals 5 separate or fused? fused
Calyx: number of sepals 0 separate or fused?N/A
Androecium: number of stamens 5 separate, fused or arranged in any special way? The filament is fused to the corolla
Gynoecium type: unicarpellate, apocarpous, or syncarpous (and # of carpels = 2)
How can you tell? (Cite the features were apparent about the number of carpels.)
The two carpels are fused together so they are syncarpous.
Flower type/ovary position: Hypogynous, or perigynous or epigynous? epigynous
Flower symmetry: actinomorphic (regular) or zygomorphic (irregular)? BOTH!
Additional distinctive features: Members of the aster family are unique because while this looks like one single flower with a lot of petals, those white “petals” are actually individual flowers formed from 5 fused petals and the interior portion has what are called disk flowers that have 5 petals fused into a tube. That is why I said the corolla has 5 petals that were fused, because each of these ray and disk flowers has 5 petals fused in some form! HOW COOL!

Common name: Wax Begonia Scientific name: Begonia cucullata
Corolla: number of petals 2 separate or fused? separate
Calyx: number of sepals 2 separate or fused?fused
Androecium: number of stamens many separate, fused or arranged in any special way?N/A
Gynoecium type: unicarpellate, apocarpous, or syncarpous (and # of carpels =0)
How can you tell? (Cite the features were apparent about the number of carpels.)
These flowers are imperfect because they only have either male or female parts (aka monoecious)
Flower type/ovary position: Hypogynous, or perigynous or epigynous?epigynous
Flower symmetry: actinomorphic (regular) or zygomorphic (irregular)? actinomorphic
Additional distinctive features: These flowers are beautiful. The flowers and plants have a waxy feeling to them and there is a large inferior ovary below the flowers.

Common name: Busy Lizzie Scientific name: Impatiens walleriana
Corolla: number of petals 5 separate or fused? separate
Calyx: number of sepals 5 separate or fused?separate
Androecium: number of stamens 5 separate, fused or arranged in any special way? No?
Gynoecium type: unicarpellate, apocarpous, or syncarpous (and # of carpels = 1)
How can you tell? (Cite the features were apparent about the number of carpels.)
I saw the one chamber and no noticeable divisions, so I think it is unicarpellate
Flower type/ovary position: Hypogynous, or perigynous or epigynous?Epigynous (the cap of the stamens is fused over the ovary)
Flower symmetry: actinomorphic (regular) or zygomorphic (irregular)? actinomorphic
Additional distinctive features: There is a spur that forms on the flower and it produces nectar.

Androecium: number of stamens 5 separate, fused or arranged in any special way?
Gynoecium type: unicarpellate, apocarpous, or syncarpous (and # of carpels =4)
How can you tell? (Cite the features were apparent about the number of carpels.)
I looked and the chamber had four parts to it.
Flower type/ovary position: Hypogynous, or perigynous or epigynous? perigynous
Flower symmetry: actinomorphic (regular) or zygomorphic (irregular)? actinomorphic
Additional distinctive features: The flower is very sticky and also contains nicotine.
