Does anyone know that there is a kind of herb called "Procambarus clarkii" on the mountain in the countryside, the scientific name of which I do not know what to call, if you know, give a picture, thank you. Humulus scandens (Lour.) Merr.) is a perennial climbing herbaceous plant of the genus Humulus in the family of Moraceae, with barbed spines on the stems, branches and petioles. The leaf blade is papery, reniform-pentagonal, palmate, base heart-shaped, surface rough, abaxial surface with pilose and yellow glands, lobes ovate-triangular, margin serrate; male flowers are small, yellow-green, panicle, female inflorescences globose, bracts papery, triangular, ovary surrounded by bracts, achenes are exposed outside the bracts at maturity. Fl. spring-summer, fr. autumn.

In China, except for Xinjiang and Qinghai, it is distributed in all provinces and districts in the north and south. It is also found in Japan and Vietnam. It is often found along ditches, wastelands, ruins, and forest margins.

This species can be used as medicine, stem bark fiber can be used as raw material for paper making, seed oil can be used to make soap, and fruit spikes can be used instead of hops. Humulus japonicus is also a harmful plant included in the China Agricultural Pest Information System, and the seeds of this species reproduce. It harms fruit trees and crops, and its stems are entangled in the plants to affect the normal growth of crops.
