Summary Long, D. G. & Grolle, R.: Studies on the genus Asterella P. Beauv. (Hepaticae). I. Nomenclatural history. ‐ Taxon 41: 65–69. 1992. ‐ ISSN 0040‐0262. Asterella P. Beauv. has been used for two different genera of Hepaticae, represented by the two protologue elements: Marchantia tenella L. and M. hemisphaerica L. Typification by M. tenella L., implied by Raddi's segregation of M. hemisphaerica L. as a unispecific genus “Rebouillia” in 1818, was first formally proposed by Evans in 1923. Unfortunately, Asterella had been effectively typified by the second element, M. hemisphaerica L., long before this, by Leman in 1823. Conservation with Evans's type is needed. Fimbraria Nees, an illegitimate later homonym of the algal Fimbriaria Stackh., and Hypenantron Corda are later synonyms of Asterella , if conserved as proposed.
