Index Filicum


Index Filicum is a discontinued series of botanical indices geared to the ferns, or monilophyte clade. As of supplement 5, the index also covered the lycophytes, and also the horsetails. There are two original works by this name, by Moore and by Christensen; this article is about the series begun by Christensen.
The forward to supplement seven stated that the supplements would be issued every five years from then on. However, since then, no further volume has been issued. Kew Gardens, the publisher of the two most recent supplements, has decided instead to rely on the International Plant Names Index.
