In message , "Rev \"Fragile Warrior\""
writes "Stewart Robert Hinsley" wrote in message ... In message , "Rev \"Fragile Warrior\"" writes He's right. We have them here, too, and I mentioned them last summer in here. Not only are there multiple heads joined together like multiple Siamese Twins, the stem going up to the flower is abnormally wide, too, like it is multiple stems merged together. They are dandelions. I know what a dandelion looks like. Giselle What you describe is, I think, a fasciated dandelion. What the OP describes does not sound like the same. "Giant dandelion" suggsts to me something in the Hieracium/Crepis/Hypochoeris area; "tight cluster of flower heads" a Sonchus (Sow Thistle), but I find the whole of Lactuceae difficult to identify. -- Stewart Robert Hinsley Okay, you've got me hooked: what's a fasciated dandelion? Giselle http://www.agron.iastate.edu/~weeds/...dID/dlion.html Fasciation is a phenotypic variation which turns up in a variety of plants. (I've seen it in dandelions, but I think the last I saw was a Daphne). In some cases it's a genetic mutation; in others it's a developmental aberration of plant growth, caused by herbicides, herbivore damage, or whatever. In fasciation stems become flattened and ribbon-like. In dandelion, where there are no vegetative stems (of any length) it affects the peduncle (flower stalk), which is homologous to a stem. As the dandelion "flower" is a compound inflorescence the fasciated condition, by changing the shape of the base of the inflorescence also distorts the inflorescence into a ribbon shape. You can find more detail with Google - "fasciation in plants" or "fasciation dandelion". -- Stewart Robert Hinsley |
