Different names of Citrus reticulata are introduced: Hay (Flora of Guangzhou), Tinea tenuifolia (Flora of Nanning), Malao Hanju (Flora of Traditional Chinese Medicine of Guangxi), Golden Keylock (Folk Herbs of Southern Fujian), Delian Zhi (Investigation of Medicinal Plants in Guizhou), Deer Grass (Guangdong Traditional Chinese Medicine Ⅱ), and so on. Source: the whole grass of Radix Scrophulariae. Origin: Born in the grassland of plains and hills, often parasitic on the roots of other plants. Distributed in Guangdong, Guangxi, Guizhou, Fujian and other places. Collection: summer and autumn collection, washing and drying. One-legged citrus is grown on the hillside grassland in plain and hilly areas. In recent years, herbicides have been widely used in plain areas, and wild one-legged citrus has almost disappeared, while hilly slopes have been reclaimed to develop sugarcane and fruit cultivation. The distribution area of wild citrus has also been greatly reduced, and the market volume has decreased year by year. Third, one-legged oranges are popular with high prices and less goods, and their operating profits are relatively rich. Every year, merchants enter the producing area to buy them, thus making one-legged oranges popular in the market.

The hillside grassland is its habitat, so pay attention to watering. Flowering in July. The fruiting period is from August to September.
