Typification of Crataegus crus-galli L. (Rosaceae) and nomenclatural notes on some related species of hawthorn

Open publisher page 7 citations

Abstract

Lectotypification of Crataegus crus-galli permits the common ten-stamened entity of the northern United States and adjacent Canada to retain its name. The correct name for the related 20-stamen form, usually called C. fontanesiana, is C. tenax. Crataegus persimilis, lectotypified here, is shown to occur in Ontario as well as New York, having been previously misidentified as C. ?bushii and C. prunifolia in Ontario. A horticultural taxon usually (but improperly) called C. prunifolia is provided with a new cultivar name.
