Rosa hemisphaerica Herrm. var. Rapini (Boissier et Balansa) Rowley Examination of living material and numerous herbarium specimens at Kew convinces me that R. rapini Boissier et Balsana is the single-flowered wild species from which the full-flowered Sulphur Rose sported some time during or before the seventeenth century. By all that is logical this name should stand with hemisphaerica subordinated as a garden variety of it. However, as the epithet hemisphaerica was published earlier (1762) we have no option but to make the species a variety of the garden rose. This topsy-turvy situation, which recurs for Rosa chinensis Jacq., R. Roxburghii Sweet and R. xanthina Lindl. makes a laughing stock of our botanical nomenclature.
