Shepherd's purse

Habitat:

Meadow near river.

Notes:

Like a number of other plants in several plant families, its seeds contain a substance known as mucilage, a condition known as myxospermy. The adaptive value of myxospermy is unknown, although the fact that mucilage becomes sticky when wet has led some to propose that C. bursa-pastoris traps insects which then provide nutrients to the seedling, which would make it protocarnivorous.
