mare's tail

The artificial banks of sand and peat which line it are generally well grown with mare's-tail, beautiful clumps of wild roses, purple vetch, great beds of sensitive ferns, and masses of Pennsylvania anemone, while the pools are decked with water-anemone.

On the shore, where it is marshy, the mare’s-tail flourishes over some acres: there is often a slight marshy odour here, which increases as the foot presses the yielding mud.

Ark is also the name of a mare's-tail cloud, or cirrhus, when it forms a streak across the sky.

Long, dappled mare's-tail clouds stretched across the pale November sky, and every now and then the sun shone out between them.

There is a disembodied skylark voice somewhere high up in the mare's-tail clouds which veil the earth from too much heat and brightness; and the young heart is unhardened and unspotted from the world.
