SOLVED: Yellow Texas wildflowers

(Becky), Lipan, TX(Zone 7b)

I posted this over in the Texas gardening forum and was hoping someone here could help me to ID these. I assume they are natives as they were found in the wild, but that may be a bit presumptuous since I don't know what they are?! Thanks in advance!

I've been unable to ID this yellow flowering weed/wildflower, well it's finally blooming so I snapped some better pics. Thanks in advance for any information, seeing this every day and not knowing what it is has really been driving me crazy!

First 3 photos are of the flower. Pic 4 is a close up of the base of the plant. It's leaves and stem are covered in a thick weblike pubescence. Last pic is of the entire plant with a plastic milk cap for scale.

This plant grows wild in poor, dry soil in Palo Pinto/Erath county, north central Texas.

Senecio ampullaceus, one of the Groundsels in TX

I am not sure of the ID, Please check up


The leaves with broadly winged leaf stalks, grow from single stems; the nodes between leaves getting shorter and shorter higher on the stem. Ovate leaves with pointed tips 3 centimeters (1.2 in) to 10 centimeters (3.9 in) long by 1.5 centimeters (0.59 in) to 4 centimeters (1.6 in) wide with tapered bases. Leaves at the lower portion of the plant have more teeth on their edges than the leaves at the upper portion of the mature plant.

Stems and leaves are covered loosely and unevenly with a mat of fine hairs, occasionally having no hairs.

Flowering stalks have 10 to 30 flower heads which as a group make a flat top to the whole plant. Each flower head is surrounded by 2 to 8 bracteoles or mini-leaves, each 1 millimeter (0.039 in) to more than 2 millimeters (0.079 in). Approximately 13 green to grayish bracts, 7 millimeters (0.28 in) to 10 millimeters (0.39 in) long surrounding 8 ray florets and an 8 millimeters (0.31 in) to 10 millimeters (0.39 in) corolla

Erigeron bloomeri doesn't occur in Texas; it's native to the Pacific northwest.

Edit: Is Plant #1 really rayless (i.e. without petals) or was it not yet in full bloom? Tetraneuris spp.?

Plays with dirt? more pix of plant 1?

(Becky), Lipan, TX(Zone 7b)

John Jebaraj, you are right! Plant #2 is Senecio ampullaceus or 'Texas groundsel':

http://davesgarden.com/guides/pf/go/98867/

Also, thanks for the recommendation on the book, I made a note of that one. Although I have to admit, I do like to come here to the plant ID forum since y'all haven't let me down yet!! I am so glad this one is solved, it was driving me nuts.

Altagardener, plant #1 wasn't in full bloom yet when I took the pics. Been a little sidetracked the past few days but I'll get back out there tomorrow and get some different shots.

You made me to think and you have given me wonderful Taxonomic exercise. Usually Taxonomists avoid YELLOW Asters and Cassias. They are real headaches for a Plant Systematist. Looking at PLANTS in their Natural Home and through displays are not always acceptable. Anyway I am happy and very glad with your comments.If you buy the Field Guide to WILDFLOWERS of North America, You would get a BOOST in 'ID'ing your own PLANTS. I saw the book in the Redmond public library in Seattle. This may be available in your local county library.

Thank you

If
Erigeron bloomeri doesn't fit, let me try again

Ok I got a few more pics of the first one, the one that is rayless in the first pic. One of the mature bloom, another of the base of the plant. It is just a tuft of grasslike leaves, the long bare stems rising from it. Seems to grow on gravelly slopes around here where water is sparse and summer heat is brutal.

Perhaps Tetraneuris acaulis for plant #1?

(Becky), Lipan, TX(Zone 7b)

Tetraneuris seems to be it. This one turns out to be tetraneuris scaposa. A plant I've almost purchased from the nursery a few times, and now I find out there are hundreds right outside my back gate! LOL

Thanks Alta :)

It is nice and I have added Tetraneuris scaposa in my Yellow Asters List of plants.
