Is osmunda a carnivorous plant? This article explains it clearly

Osmunda is a wild vegetable, a perennial herbaceous plant of the genus Vicia in the family Osmundaceae of the ferns, and its tender leaf stalks can be eaten as a vegetable. So, is osmunda a carnivorous plant?

1. Is osmunda a carnivorous plant?

Osmunda is not a carnivorous plant, it is just an ordinary wild vegetable. The tender stems are generally collected in April-May, with a collected length of about 20 cm. After collection they are blanched in water, and then cooked and eaten.

2. What does carnivorous plant mean?

A carnivorous plant is a plant that can attract and capture prey and can produce digestive enzymes and absorb the nutrients released by decomposition, and the prey is mostly insects and arthropods. In nature, there are more than 630 species of such plants, such as Nepenthes, Venus flytrap, pitcher plant, sundew, etc.

1. Nepenthes: It has a unique organ for absorbing nutrients—the pitcher, which is cylindrical in shape, slightly swollen at the lower part, with a lid on the pitcher mouth, and can prey on insects. The inner surface of the pitcher lid can secrete a fragrance to lure insects; the pitcher mouth is smooth, and insects will slip into the pitcher, be drowned by the liquid secreted at the bottom of the pitcher, and the insect body nutrients are decomposed and gradually digested and absorbed.

2. Venus flytrap: The tip of the leaf has a trap that closely resembles a “shell”, and the leaf margin contains nectar glands that secrete nectar to lure insects close. When an insect enters the leaf surface and touches the sensory hairs of the sensory organ twice, the two lobes of the leaf will quickly close and clamp it, and the insect will be digested by the digestive fluid secreted by the glands on the trap.

3. Pitcher plant: The leaves are like pitchers, and there is a trapping pouch in the pitcher. The opening of the pouch wall is smooth and bears nectar glands that can secrete sweet nectar to lure insects to come and fall into the pouch. The pouch wall is smooth and contains digestive fluid, which can secrete digestive enzymes to decompose the insects, and then they are absorbed by the proteolytic enzymes decomposed by the glands formed by the parenchyma cells of the inner wall.
