Citrus medica var. sarcodactylis, or the fingered citron, is an unusually shaped citron variety whose fruit is segmented into finger-like sections, resembling those seen on representations of the Buddha. It is called Buddha's hand in Chinese (佛手柑), Japanese (仏手柑), Korean (불수감; 佛手柑), Vietnamese (quả tay phật), and French (Main de Bouddha).
The different cultivars and variations of this citron variety form a gradient from "open-hand" types with outward-splayed segments to "closed-hand" types, in which the fingers are kept together. There are also half-fingered fruits, in which the basal side is united and the apical side fingered. The origin of this kind of citron is commonly traced back to South or East Asia, probably northeastern India or China, where most domesticated citrus fruits originate.
