FRUITS

Sugar maple Acer saccharum (Aceraceae) seen in my yard on 20th Ave. This is a samara fruit type, which was once a corymb inflorescence.

Southern catalpa Catalpa bignonioides (Bignoniaceae) found at the end of my block on 20th Ave, This is a capsule fruit type that was once a panicle inflorescence.

Ohio buckeye Aesculus glabra (Sapindaceae) seen in Iuka Park. This fruit type is a nut that was once a raceme inflorescence.

Red-panicle dogwood Cornus racemose (Cornaceae) seen in the Iuka ravine. This is a drupe fruit type from a panicle inflorescence.

Redbud Cercis canadensis (Fabaceae) seen on Summit St near the Iuka ravine. This is a legume fruit type from a raceme inflorescence.

Dandelion Taraxacum officinale (Asteraceae) found in my neighbor’s yard on 4th St. This is an achene fruit type from a capitulate inflorescence.

Flowers

 

Common morning glory Ipomoea purpurea (Convolvula) seen in the alley near Iuka Park. This actinomorphic flower has 5 parts, fused petals, a syncarpous gynoecium, and superior ovary. It is a solitary inflorescence. Above is two photos to show the heart-shaped leaves and trumpeting flower.

Spotted jewelweed Impatiens capensis (Balsaminaceae) see along the road in Iuka Park. This zygomorphic flower has a 3-lobed corolla and a modified sepal lobe that may serve as a pad for pollinators. I think this is a perigynous flower with a superior ovary and apocarpous gynoecium. It is a solitary inflorescence. Seen beneath the flower are the awesome seed pods that explode when touched; for this, jewelweed is sometimes called touch-me-not.

 

While many of these species look similar, I’ve decided that this is early goldenrod Solidago juncea (Asteraceae) based on my finding it near a cornfield at Waterman Farm and the description of the leaves. The individual flowers are arranged in a capitulate inflorescence and splay from the stalk in a raceme-like fashion. Like other asters, they have fused petals in the disc flowers and very zygomorphic ray flowers with an inferior ovary. I think this flower has a syncarpous gynoecium. These guys were everywhere in this field. Pretty.

This is such a cool flower, so I didn’t want to give up on it! I don’t think it’s cowbane Cicuta virosa (Apiaceae) but that’s the closest flower I could find in the book. I photographed it in the alley near Iuka Park. I like it for its strongly-fused hypanthium, perigynous insertion with a superior ovary and (probably) syncarpous gynoecium. The compound umbel inflorescence makes this plant stand out, even though I couldn’t find it in Newcomb’s field guide. Also, there is a bee!

Nuttall’s lobelia Lobelia nuttallii (Campanulaceae) seen at Waterman Farm. This zygomorphic flower has 5 parts, partially fused, a syncarpous gynoecium, and is epigenous with an inferior ovary. The inflorescence is a spike-like raceme.

White clover Trifolium repens (Fabaceae) seen at Waterman Farm. These zygomorphic perigynous flowers have 5 fused petals, a superior ovary, ripen into a unicarpellate gynoecium, and grow in a capitulate inflorescence. All these big words, but I’ve always just called it clover!
