I had to link a photobucket album as the pictures are to large to upload and I am an idiot at computers.. Here is a link that might be useful: rat tail

Well then we are entering the territory of the wild lettuce family. I don't think anyone mentioned a smell from the leaves, but a milk colored substance coming out of the stem when you break one (or not) would be a featu to look for to help narrow down what you might have. Wild lettuces are a large family of plants, so finding your particular weed might be tough, but look at some pictures of them or sow thistles (not quite the same as wild lettuce but similar). Here is a link that might be useful:

Philmont... I just checked the rest of my radishes and there leaves are only slightly hairy on the undersides...pretty smooth above. I guess you could always pull the soil away from the base a little bit and see if any roots below are forming. At the stage for me radishes root tops (not the greens) are viewable from the top of the soil. The wild radish don't have roots like cultivated species so those would be abscent. Vera

WELL...last night someone on name that plant forum indicated that it was called Yellowrocket, which led to finding that it is probably a very close relative of Yellowrocket: Wild Radish. Whis is a very close relative to Wild Mustard :-) The only reason it can't be Yellowrocket is because the stems and leaves have tiny hairs, which indicates it is Wild Radish. However. I have seen pics of Wild Radish now on Google Images that don't look like this plant, and some that show Yellowrocket looking dead-on accurate, save for the leaves. Ha. At any rate, I'm pulling them up...tis' not to be... Thanks so much for your help, timbu and fammsimm. Now I am also familiar with two other kinds of weeds, so if I spot them, I'll know right away :-) Joanna
