What is "buddha's hand"

n. (taxlink Citrus medica var. sarcodactylus variety noshow=1), a fragrant variant of citron whose fruit is segmented into finger-like sections,

Buddha's hand, Citrus medica var. sarcodactylis, or the fingered citron, is an unusually shaped citron variety whose fruit is segmented into finger-like sections, resembling a human hand. In Japanese it is called busshukan (仏手柑 or ブッシュカン).

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 the Far East, probably northeastern India or China, where most domesticated citrus fruits originate.
