Abstract
THE hawkweeds have long been known as a group of plants presenting peculiar difficulties to taxonomists. The general facts can be simply stated : in most parts of the generic range the hawkweeds are more or less locally limited entities which morphologically differ definitely, but not greatly, from other entities. These microspecies, or whatever they be called, come true in their differential characters from seed. In the British Isles, the northern and western parts are richest in Hieracia, and in the past their study has attracted many British botanists. The late Mr. H. W. Pugsley published "Notes on British Hawkweeds" in 1920, so that it is safe to say that the present prodromus is the result of more than a quarter of a century's investigations.
