Chromosome numbers in plants -Reply

[Hugh D. Wilson]

I was unable to find a count for Chenopodium quinoa (a much counted
species) MBG VAST file, which suggests that IPCN incorporation is
incomplete.  Since the user interface forces a species-by-species
check (no tabular output) its difficult to determine how many counts
are available in this dataset (maybe someone from MBG can comment).

A check of the Kew DNA database at:

http://www.rbgkew.org.uk/cval/database1.html

produces two counts for Chenopodium (the literature carries counts
for at least 30 species of the genus)

Anybody know of any other sources of plant chromosome count info on
line?

This demonstrates the tendency to put data of local disciplinary
interest (type specimens) on line while ignoring systematic data
that might have a broader application.
