Ribes Ribes Ribes is a genus of about 150 known species of flowering plants native throughout the temperate regions of the Northern Hemisphere. It is usually treated as the only genus in the family Grossulariaceae, but a few taxonomists place the gooseberry species in a separate genus of "Grossularia". Sometimes "Ribes" is instead included in the family Saxifragaceae. The genus "Ribes" includes the edible currants (blackcurrant, redcurrant, white currant), the gooseberry, and several hybrid varieties. It should not be confused with the dried currant used in cakes and puddings, which is a small-fruited cultivar of grape (Zante currant). "Ribes" gives its
Allium nigrum to 60 cm long and 2.5 cm across. Later the leaves become reflexed. Scapes are smooth and round in cross-section, 80–100 cm tall. The scape carries a dense umbellate inflorescence with star-like flowers up to 9 mm across; tepals white with a green midevein; anthers purple or yellow. The ovaries are black-green (but flushed with red in the Levant) in anthesis, but green when younger or following anthesis. Type species of Subgenus (Section) "Melanocrommyum". Molecular evidence suggests that "A. nigrum" is a polymorphous species consisting of several infraspecific groups. Alliances: Allium nigrum alliance: "Allium nigrum" L. and "A. multibulbosum" Jacq.
