Abstract

The perennial species of Trifolium Linnaeus section Involucrarium Hooker are revised. A key to the species, descriptions of species, synonyms, typification, distribution maps, and notes are presented. The following chromosome numbers are reported as new: T. mucronatum Willd. ssp. mucronatum, 2n = 16; T. mucronatum ssp. vaughanae J. M. Gillett, 2n = 16; and T. wormskioldii Lehmann, 2n = 16. The following combinations are made: T. mucronatum Willdenow ssp. lacerum (Greene) J. M. Gillett, T. monanthum A. Gray ssp. parvum (Kellogg) J. M. Gillett, T. monanthum ssp. tenerum (Eastwood) J. M. Gillett, and T. monanthum ssp. grantianum (Heller) J. M. Gillett. A new species, Trifolium siskiyouense J. M. Gillett and a new subspecies, T. mucronatum ssp. vaughanae are described. Taxonomic problems are discussed.
