The genus Crataegus, to which hawthorns belong, is a huge one. There are certainly 200 species, largely in North America, but if 'microspecies' are included, then there could be as many as 1000. Here in Britain we have just two native species (several others have become naturalised) and both are found in Stefen Hill pocket park.
Unsurprisingly most of those present are Common Hawthorn, Crataegus monogyna. Its sweet-smelling blossom is now beginning to appear. The leaves are deeply dissected, jagged even, and quite distinctive.
