Index to Plant Chromosome Numbers (IPCN) The Index to Plant
Chromosome Numbers is an NSF funded project that aims to extract
and index original plant chromosome numbers of naturally
occurring and cultivated plants published throughout the world.
A committee of voluntary contributing editors, located in
various parts of the world, reviews sets of serial titles
assigned to them and returns the information to the editors for
collation in the Index and database. Chromosome indexes are
published at two or three year intervals. The Index to Plant
Chromosome Numbers project has been based at the Missouri
Botanical Garden since 1978. Data from published indexes from
1979 onward are available for consultation through this
facility. For additional information, see the last supplement by
