To Lillian:  This may have been answered already, but if not here's some
numbers.

G. pratense             2n = 28
G. himalayense          2n = 28
G. wallichianum         2n = 28
G. macrorrhizum         2n = 46
G. sanguineum           2n = 84

G. x cantabriense = G. dalmaticum x G. macrorrhizum (46 x 46)
G. x monacense = G. phaeum x G. reflexum (28 x 28)
G. x oxonianum = G. endressii x G. versicolor (26 or 28 x 28)

These are courtesy Peter Yeo's "Hardy Geraniums" (Chapter 7, 'Chromosome
Numbers & Hybrids').  Highly recommended.
