Index Filicum

Supplement VI provides an index to the family, generic, infrageneric and specific names of ferns and fern allies published between 1976 and 1990. It is a continuation of Carl Christensen s Index Filicum (1906), the three supplements prepared by Christensen (1913, 1917 and 1934), the fourth by Pichi Sermolli (1965) and the fifth by Jarrett (1985). It presents the names as published, without taxonomic judgement, following the precedent set by Supplement V. Each name listed is accompanied by bibliographic detail and basionym entries are included."
