Abstract

Ee B. W. van: The contribution of Johann Friedrich Klotzsch to the taxonomy of Croton (Euphorbiaceae) and associated genera. — Willdenowia 41: 15–33. — Online ISSN 1868-6397; © 2011 BGBM Berlin-Dahlem. doi:10.3372/wi.41.41102 (available via http//dx.doi.org/)The contribution of J. F. Klotzsch to Croton taxonomy is summarised through a review of the original literature, an examination of specimens and taxonomic decisions. The currently accepted names are given for Klotzsch's taxa associated with Croton. The new combinations Astraea comosa and A. jatropha are made. Lectotypes are designated for C. comosus, C. comosus var. major, C. comosus var. minor, C. compressus, C. essequiboensis, C. hircinus, C. jatropha, C. leucadenius, C. lobatus, C. multispicatus, C. muricatus, C. sphaerogynus, C. tricolor and Lasiogyne brasiliensis. Neotypes are designated for Argyrodendron bicolor and Cleodora sellowiana. Epitypes are designated for Croton hircinus and C. multispicatus.
