    Hi Phil, looks like either Hypochoeris glabra or Scorzoneroides autumnalis. But species in this section of the Asteraceae need close examination of the inflorescence and achenes to ID.

    Thanks Mike I now see why I have problems in IDs these species

    It doesn't help that they are variable in appearance depending on shading, moisture and fertility! The Illustrated Guide to Common Weeds is a good start, but needs to be used in conjunction with Flora IV to see what other similar species are around. They can be conspicuous weeds of some places - such as in your photos.

    Crepis foetida subsp. foestida - see http://www.nzpcn.org.nz/flora_details.aspx?ID=3737 - its more common in the south eastern North Island but I have seen, and collected it from Canterbury

    Peter, why not C. vesicaria? Whenever I endeavor to ID similar plants here in Canterbury I end up at C. vesicaria, of course I could be getting it wrong.

    Probably - I prefer specimens than images in this group. What I really wanted to say is that this is not Hypochoeris glabra or Scorzoneroides autumnalis its Crepis
