Welcome to Flowers and Fruits!  The first four will be focused on flowers, and the last four will be focused on fruits.

Blue Mistflower (Eupatorium coelestinum).

Family: Asteraceae

Inflorescence: Terminal corymbose panicle

 

 

 

 

 

 

 

 

This Mistflower was found along the walkway in Iuka Park.

Mistflowers have opposite leaves that are toothed and triangular in shape.  This flower is radially symmetric.  Each flowerhead consists of as many as 50 florets, which have 5 lobes that are fused, and a long style which gives off the “hairy/fuzzy” appearance.  This flower has 5 stamens, and fused anthers. While this is an Asteraceae member, there are no ray flowers present, only disk flowers.  This flower is epigynous as it has an inferior ovary.  This flower has one compound pistil of 2 carpels, making it syncarpous.

 

Great Lobelia (Lobelia siphilitica).

Family: Campanulaceae

Inflorescence: Spike-like raceme

 

 

 

 

 

 

 

 

This Lobelia was found along the walkway of Iuka Park.

The Great Lobelia has finely toothed, alternate leaves.  This flower is bilaterally symmetric with each flower having two lips.  There are three lobes on the lower lip, and two lobes on the upper lip.  There are 5 petals and 5 sepals that are fused.  This has 2 fused carpels, making it syncarpous.  The anthers and stamens are fused into a tube.  The ovary is inferior, making it epigynous.

 

Curled Dock (Rumex crispus).

Family: Polygonaceae

Inflorescence: A stalked panicle of racemes

 

 

 

 

 

 

 

 

This Curled Dock was found along the Olentangy Bike Trail.

This flower has alternate, simple leaves.  Curled Docks have radial symmetry.  The flowers are 6-parted with the petals and sepals fused.  There are two whorls of the petals and sepals, 3 on each whorl.  There are 6 stamens and 3 styles as well.  The pistil has 3 fused carpels, making it syncarpous.  This ovary position is hypogynous.

 

Turtlehead (Chelone lyoni).

Family: Scrophulariaceae

Inflorescence: Terminal raceme

The Pink Turtlehead was found in the wooded area of Iuka Park.

This Pink Turtlehead has simple leaves that are oppositely arranged.  The flowers are bilaterally symmetric.  This flower has 5 petals and sepals that are fused, and arranged in 2 upper lobes and 3 lower lobes. There are 4 stamens.  The flowers are 2-lipped in clusters.  This flower has one pistil with 2 carpels, making this syncarpous.   This ovary is superior.

 

Black Maple (Acer nigrum).

Family: Sapindaceae

This maple was found in a grassy area to the side of the Olentangy Bike Trail.

Black maples have simple leaves that are opposite and palmately compound.  The fruit of maples is a winged fruit called a samara.  A samara is a winged nut or achene that contains one seed.

 

Cutleaf Teasel (Dipsacus laciniatus).

Family: Dipsacaceae

Inflorescence: Cylindrical Cluster/Heads

This was found on the Olentangy Bike Trail.

The Cutleaf Teasel has a spiny stem.  The leaves are opposite and deeply lobed.  The flowers are white and 4-parted and they have irregular petals, along with 4 stamens.  The ovary of this is inferior, making it epigynous.  While this flower has 2 united carpels, it aborts one, so there is only 1 chamber in the ovary.  The fruits of the Cutleaf Teasel are achenes.  Achenes are small, dry, one seeded fruits.  Achenes do not open to release seeds.

 

Shumard Oak (Quercus shumardii).

Family: Fagaceae

Flower Inflorescence: Staminate Catkins

 

 

 

 

 

 

 

 

This was found outside of Jennings Hall, on Ohio State’s Campus.

 

This Shumard oak has deeply lobed leaves with bristle tips that are alternately arranged.  The flowers are radially symmetric but the petals are absent.  This oak produces a fruit that is considered a nut, and these fruits are acorns.  The acorn cup is gray, finely hairy, and shallow, covering about 1/3 of the nut.

 

American Pokeweed (Phytolacca americana).

Family: Phytolaccaceae

Inflorescence: Raceme

 

 

 

 

 

 

 

 

This was found in a woody area in Iuka Park.

American Pokeweed has reddish purple stems with large, alternate leaves.  The flowers have five petal-like, rounded sepals, 10 stamens, and the pistil has united carpels, making it syncarpous.  This flower has a superior ovary.  The fruit of this is a berry, dark purple when mature.  A berry is a fleshy fruit that does not have a hard stone/pit in the middle.  A berry is derived from a single flower that has one ovary.
