Dicentra, a genus of Fumariaceæ, of which one species, the 'Chinese lantern plant,' D. spectabilis (described by Linnæus in 1753, but only introduced from Asiatic into British flower-gardens in 1846), has become a universal favourite on account of its long racemes of drooping, delicate, rosy-pink flowers. In America it is commonly known as 'Bleeding Heart.' It is a herbaceous perennial of easy propagation. There are several other North American species, one of which, D. formosa, is a favourite and very showy garden-plant. Owing, in the first instance, to a misprint, Dicentra has been as frequently called Dielytra, the original mistake having become consecrated by habit.
