The woods in North Wales were often covered with carpets of moss and banks of ferns plus some very lovely trees.
Under these there were patches of a lovely sprawling yellow flower I was unfamiliar with.
The flower is common cow-wheat (Melampyrum prayense sp pratense )
This is from the broomrape family and is a hemi parasitic plant. This darker yellow is common in the north and on acidic soils, on alkaline soils in the south the flowers are paler yellow.
The seeds are toxic to deter animals from eating them.
This small flowered slightly spindly plant is very attractive in the woodlands.
