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
Solanum nigrum varieties and forms described. The recognized subspecies are: 1. "S. nigrum" L. subsp. "nigrum" — glabrous to slightly hairy with appressed non-glandular hairs 2. "S. nigrum" L. subsp. "schultesii" (Opiz) Wessley — densely hairy with patent, glandular hairs The Solanum nigrum" complex — also known as Solanum" L. section "Solanum" — is the group of black nightshade species characterized by their lack of prickles and stellate hairs, their white flowers, and their green or black fruits arranged in an umbelliform fashion. The "Solanum" species in this group can be taxonomically confused, more so by intermediate forms and hybridization between the
