please where are botanical aggregates defined?
Hello, I am unsure when to use the aggregates given in the species drop down list because in my mind it implies there are a number of species that I should understand before not choosing the agg. However I wanted to record Ligustrum vulgare: drop down list for Lig vul gives Ligustrum vulgare, Ligustrum vulgare agg. and the vulgare x ovalifolium hybrid. I cannot find any reference to an aggregate (Stace 3, NBN, BSBI Atlas). It has been suggested that iRecord uses the term when distinguishing species might be difficult rather than just recording to genus?
