Sow-thistles are an exception; they are related to Dandelions, Lettuces, Hawkweeds et al (Lactuceae). Thanks Stewart. The plot re. plant relationship thickens here a bit, but all of those you mention are in the Compositae family, though in different genera and species of that group. Some of them are also mentioned as species or sub-species within the Asteraceae family, and use the synonym Lactuca for differentiation. Plantfinder gives twenty varieties of Sow-thistle, with the common Sow-thistle listed as Sonchus oleraceus. Phew. Managed to include a word from the subject line in the quote above. Anyway. I just wanted to add to these observations concerning nomenclature that there may well be a _really_ grand re-ordering of this when they start classifying according to DNA and individual genes. It's already begun to happen hasn't it? Rspct Hussein |
