This database contains descriptive details of the type
specimens of more than 10,000 extinct
plant genera.
The Field Headings were established by the "Frankfurt
Declaration" of IOP in 1990 and
the details
comprised the first version of this database, PFR1,
which was published in 1992. Most Field
Headings
are blank, and do not show here, and most genera
described since 1985 are missing.
Please send complete data on new genera to the IOP
office,
