Fruit 1: Common Burdock (Arctium minus)

The spiky fruits of Common Burdock

The spiky burs of the common burdock contain fruits in the form of a multiple of achenes. This plant was found along the edge of the Olentangy bike trail, around some trash and brambles. Having multiple clusters of flowers (I believe there were multiple flowers on each spiny fruit), I believe the inflorescence type is a capitulum. The gynoecium type of each flower is syncarpous. The common burdock comes from the Asteraceae family.

Fruit 2: Norway Maple (Acer platanoides)

Hear you can see a cluster of fruits from one of the individual “umbels” on the panicle.

The paired Samaras of the Norway Maple.

The fruits of the Norway Maple come in the form of paired Samaras. The gynoecium type is syncarpous. Each cluster of fruits originates from the same point, and these clusters occur alternately long the branches of the tree- thus, I believe the inflorescence type is a panicle. This tree was found on the edge of the Olentangy river trail, right along a fence that was overrun with vines. The Norway Maple is in the Sapinaceae family.

Fruit #3: Black Walnut (Juglans nigra)

The green drupe of the Black Walnut.

The Black Walnut tree in all it’s glory.

The fruit of the black walnut comes in the form a bright green drupe, with a single seed enclosed in a hard endocarp that’s inside inside of a fleshy ovary. This walnut was found in a rather open space between the Olentangy river trail and Tuttle Park. The inflorescence type is a spike, although this is quite hard to tell when the plant is not in flower. The gynoecium type is unicarpellate. The  black walnut hails from the Juglandaceae family.

Fruit #4: Common milkweed (Asclepias syriaca)

Milkweed follicle

Milkweed plant

The Common Milkweed’s fruit comes in the form of a follicle. The inflorescence type is an Umbel, although, that can’t be seen in either of my pictures. I found this milkweed on the very edge of the bushes along the Olentangy river trail, in a spot that had direct sunlight. They gynoecium type is unicarpellate. The common milkweed comes from the Apocynaceae family.

The Pokeweed with it’s raceme of white flowers.

The flowers of the Pokeweed plant have a raceme florescence type, radial symmetry, a syncarpous gynoecium, about 8 stigmas, 8 carpels, 5 petals, no sepals, and a hypogynous insertion of flower parts. Some of the flowers are starting to fruit. I saw this pokeweed along the Olentangy river trail, in the same polluted area where I found the Burdock.  It belongs to the Phytolaccaceae family.

Flower #2: Smooth Aster (Aster laevis)

Smooth Aster flower

I saw this Smooth Aster very close to where I found the Burdock and the Pokeweed, altough it was closer to the edge of the bramble patch. The florescence type is a capitulum. Flowers are both zygomorphic and actinomorphic, and it has a 2-part, syncarpous gynoecium and 5 stamens. Flowers have 5 part fused gynoecium and a 5-sepaled calyx that form a pappus. The insertion of flower parts is epigenous. It belongs to the Asteraceae family.

Flower #3: Common Evening Primrose

Common Evening Primrose

I found this Common Evening Primrose in an open patch of dry grasses along the Olentangy river trail. The flower of the Common Evening Primrose has 4 petals, 4 sepals, 8 stamen, and a 4-part, syncarpous gynoecium. The insertion of flower parts is epigenous. The Common Evening primrose belongs to the Onagraceae family.

Flower #4: Virgin’s Bower (Clematis virginiana)

The nice white flowers of the Clematis.

The Virgin’s Bower was growing as a vine on a bush along the Olentangy river trail. The flower consists of 4 petals long, separate petals (which may be sepals) and no sepals (unless the petals are sepals, in which case there are no petals). The parts insertion is hypogynous with a syncarpous gynoecium and many stamens and carpels. The florescence is a  panicle. The Virgin’s Bower hails from the Ranunculaceae family.
