Butter-and-eggs, Linaria vulgaris

This showy little snapdragon is one of several attractive non-natives that seem to prefer growing along railroads. Others include Railroad Vine (Convolvulus arvensis), Little Barley (Hordeum pusillum), Viper's Bugloss (Echium vulgare), and Carolina Cranesbill (Geranium carolinianum), just to name a few of the many. Photographed along the C & O Railroad near New Buffalo, Michigan.

The land of flowers 2

I am working at getting a handle on the plants I am seeing at work. Sometimes, the desire, effort, or time is lacking while I am working, but putting the photos online helps me get better at paying attention.
Hypoxis juncea - Yellow stargrass
In the dry prairie at Myakka River State Park.

Lyonia lucida
In the dry prairie with blueberries at Myakka River State Park.

Nuttallanthus (formerly Linaria)- probably floridanus or canadensis.
This flower was growing profusely throughout cattle pastures and along roadsides.

Sisyrinchium - Blue-eyed Grass from Sarasota County, FL. Feel free to ID, I'll try to key later. I tried for several days to get the camera focus on these guys.

Salvia lyrata - Lyreleaf Sage
I did not see many individuals of this flower blooming yet.

Hypericum from Manatee County, FL. Feel free to take a shot at ID. Sorry for the incomplete ID.

Emilia fosbergii - Florida Tasselflower
This 'weed' was growing very commonly in sandy margins of ag fields in Manatee County.

Fumaria officinalis - drug fumitory
Growing very weedy in a disturbed site in Hillsborough County. I thought it was a Corydalis at first.
