At this time of year there are relatively few plants still in flower, but this is one of them. Ivy leaved toadflax (Cymbalaria muralis) still has the occasional flower but they have to be searched out. As discussed earlier it even has its own wall community.
This view shows the lower corolla lip (the upper part of the corolla has been removed)with 2 white and yellow swellings called the palate. Also visible are 3 of the 4 stamens which are attached to the corolla tube. C muralis is one of the figwort family or Scrophulariaceae. This family are characterised by their zygomorphic (having only one plane of symmetry) flowers, although they are not the only family to do so (see for example the Labiate family).
The notebook sketches show more of the diagnostic features of this species. This includes from top left, the five lobed corolla with swollen palate and spur. Top right shows the calyx which is shorter than the corolla and has just one stigma. Bottom right is the upper lip of the corolla shown from the inside with one stamen still attached near its base. Note the fine translucent hairs, midway to the edge of the corolla. Bottom left is a sketch of the creeping nature of the plant, with long stalked ivy like leaves attached at various points to the main stem. The junction of the main stem and leaf stalk (petiole) is also where the long stalked flowers may be attached.
