Although there was no surface water I suspect there was something under the surface where this plant was growing. A slightly greener area at the lowest part of the field which was otherwise very dry. I have looked through some pics of Mallows, Malopes and Lavateras for my area but haven't seen anything which quite matches this plant. That doesn't really mean anything, of course, as I am not a botanist
The flowers were small, less than an inch across. Leaves quite sparse - though it was growing up through other plants. More delicate looking than the photos I have seen on the internet. Can anyone help?
