hybrid Viola

Andy I note that Field Pansy x Heartsease Pansy Viola x contempta is not listed. It occurs in Stace 3 and in the recent BSBI handbook on Violas. 

Thanks Dave - will add to my list of future hybrids to consider adding.

Many hybrids are not included as they don't (usually?) occur in the absence of the parent species. The ones that are deemed countable are the ones that do, and are given a number in Stace (rather than the numbers of the parents, 12 x 14, as in V tricolor x arvensis, of this taxon).
