Nepenthes is the general term for all species of Nepenthes. It has a unique nutrient-trapping organ, the trap cage is cylindrical, the lower half is slightly enlarged, and the lid of the cage has a lid, which is named because it is shaped like a pig cage. At the same time, Nepenthes is also called boots grass, because the shape looks like small boots.
Nepenthes is a tropical carnivorous plant, and the cap of the bottle-shaped body can separate the secret fragrance and lure insects. The mouth of the bottle is smooth, and the insect will be slipped into the bottle, drowned by the liquid secreted at the bottom of the bottle, and decompose the nutrients of the insect body, and gradually digest and absorb.
The pig cage grassland is mainly produced in the tropical area of the old continent. There are about 170 species of wild plants in the world. There are only one species in Guangdong, China, and there are more than 1,000 species of horticultural species.
Nepenthes, although wildly distributed in Guangdong’s Sanling Mountains and Leizhou, are rarely used. It was not until the 1990s that the fine varieties of Nepenthes introduced from China were mainly used for flower exhibitions.
