Bottlegrass is a famous type of insectivorous plant. These bottle-leaves of bottlegrass are traps for catching insects. The inner wall of the bottle is very smooth and has nectaries, which can secrete sweet honey juice to lure the insects to hook. There is also a row of spiked hair on the bottle wall, which can help catch insects and have a lip at the top. . The bottom of the bottle contains the liquid, which is the "drencher" that the bottle grass is set to catch insects. When the insects came to eat honey with a sweet taste, they climbed to the edge of the slippery bottle. They wanted to get into the bottle to eat more sweets, and they would fall to the bottom of the bottle and fall into the liquid. If the insects that fall into the bottom of the bottle attempt to climb out, the puff around the inner wall is like a spear in the guard's hand blocking its way, making it impossible to escape; if the insect tries to fly out, its wings will bump or fall. The inner wall, and fell into the liquid again. In this way, insects are drowned in a "drenched" alive; then the inner wall secretes digestive enzymes, digests and decomposes, and then absorbs the decomposed amino acids by parenchyma cells.
