Pinguicula vulgaris L.
The usual urban, dense, dense milk
Agglomeration of small, fat-like shiny rosette leaves grow densely printed for the moist soil in swamps and marshy meadows. The flowers have some resemblance to violets, but the town is actually a dangerous plant - for small insects. The leaves are covered with glands - up to 25000 on a square inch! - Which secretes a sticky mucus in which insects are trapped. While leaf curl over the victim begins to other glands secrete an enzyme that dissolves the insect. After about three days is only indigestible parts such as wings and legs remain, and even these disappear gradually. At the dissolution of the insects secrete tätörtsbladen an antiseptic herbicide that inhibits victims' decay.
