A genus of eight species in S. America, placed in the tribe Sanguisorbeae of the Rose family, with Acaena, Alchemilla, Sanguisorba, and Poterium, to name only those genera best known in gardens; hybrids with Acaena have been recorded, despite the great differences between their fruits (Bean 1981, Mabberley 2017). In Margyricarpus the fruit is an achene, enclosed in the fleshy calyx-tube that swells to make a single berry-like fruit. The formerly monospecific Margyricarpus now includes Tetraglochin, but only M. pinnatus is known to be in cultivation.
