Abstract is: Lychee (US: /ˈliːˌtʃiː/ LEE-chee; UK: /ˈlaɪˌtʃiː/ LIE-chee; Litchi chinensis; Chinese: 荔枝; pinyin: lìzhī; Jyutping: lai6 zi1; Pe̍h-ōe-jī: nāi-chi) is a monotypic taxon and the sole member in the genus Litchi in the soapberry family, Sapindaceae. It is a tropical tree native to the Guangdong, Fujian, and Yunnan provinces of Southeast and Southwest China, where cultivation is documented from the 11th century. China is the main producer of lychees, followed by Vietnam, India, other countries in Southeast Asia, the Indian Subcontinent, Madagascar and South Africa. A tall evergreen tree, the lychee bears small fleshy fruits. The outside of the fruit is pink-red, roughly textured, and inedible, covering sweet flesh eaten in many different dessert dishes. Lychee seeds contain methylene cyclopropyl glycine which can cause hypoglycemia associated with outbreaks of encephalopathy in undernourished Indian and Vietnamese children who had consumed lychee fruit.
