Family - Asteraceae
Flowering - April - June.
Habitat - Rocky open woods, thickets, stream edges.
Origin - Native to U.S.
Other info. - This species can be found throughout much of Missouri but is apparently absent from the west-central and northwest portions of the state. The plant is probably the easiest of the Erigeron species to ID in Missouri because of its densely hairy stems and its big flower heads. The plant spreads by stolons and often forms little colonies.
The species epithet - "pulchellus" means "pretty."

What are these succulent species? I am especially interested in the Gasteria-like plants.

Abby Gill：The first and third are probably pachyphytum, the second one maybe haworthia, the fourth one echeveria lola, the seventh a type of echeveria, and the last one some kind of sedum. I'm not 100% sure though.
meriunkat：the second picture on the last row had a small sedum Morganianum "donkey tail"

Family - Asteraceae
Disk flowers - No info. yet.
Flowering - June - November.
Habitat - Fields, disturbed sites, waste ground, roadsides, railroads.
Origin - Native to U.S.
Other info. - This weedy species can be found throughout Missouri. It spreads rapidly and is one of the most common plants in the state. The more mature plants are apically branched but the plant can flower when quite small and unbranched.
The plant was traditionally used to treat many ailments such as diarrhea, kidney stones, diabetes, and nosebleeds. Many people are allergic to its pollen and can get a reaction just by handling the plant. IT is one of the leading causes of fall allergies. Livestock animals seem to ignore the plant because of its bitter taste.

Family - Asteraceae
Flowering - April - August.
Habitat - Rocky open woods, prairies, glades.
Origin - Native to U.S.
Other info. - This tiny species can be found in just a handful of southwestern Missouri counties. It is easily overlooked in the field because of its small size but is easily identified as nothing else in its family resembles it. The thin, wiry stems and scale-like leaves are good characters to look for. A similar looking species which could occur with this one is Arenaria patula Michx. but this latter species has opposite leaves and flowers with 4 petals. Chaetopappa has alternate leaves and a composite flower.

Family - Rosaceae
Flowering - May - July.
Habitat - Bluffs, wooded slopes, rocky and moist woodlands, ravines.
Origin - Native to U.S.
Other info. - This attractive species can be found in the southeastern half of Missouri but is mostly absent from the bootheel. The plant is easy to identify because of its big sprays of whitish flowers that quickly become tan when drying. The large, compound leaves are also diagnostic.
Aruncus was used by natives as a tea to reduce bleeding after childbirth. The same tea was also used as a soak for tired, swollen feet. Steyermark reported that the plant grows well from seed and does well in a garden setting. It would make a striking cultivated plant.

Family - Apiaceae
Flowering - May - July.
Habitat - Dry rocky woods, along streams, rich woods, wet prairies, shaded bluffs, swamps.
