Slight resemblance to :Skullcap, but Common Cow-Wheat is yellow not blue.

This is a  Hemi-parasitic plant, meaning that it relies on obtaining some of its' nutrients from the roots of nearby plants.

The leaves are hard to see blending in well with the grass it grows so well amongst. The yellow flowers always grow in pairs up the stem. The first pair to emerge being at the top of the (square) stem.

The sepal teeth are very long and have brownish markings.
