Line 85: a question: how far is this statement true? Over the last two centuries the plant species that are widespread and common most likely have specimens present in Herbaria (even sometimes overrepresented!). On the contrary, the plants that are rare or with a very restricted distribution may have very few specimens in Herbaria (for example one voucher in one Herbarium). In this case, one would be happy if they are identified at genus level.
