The Hawthorn tree is one of our more familiar hedgerow trees, but we also see it growing locally alone in a field or on a riverbank, and when we do we can recognise it by its rugged, stunted shape and resilient attitude, its thorns, its bright red autumn berries and its white, or sometimes pink, spring blossom.

Those we see in the fields around Bridge are more generally the Common Hawthorn, but there is another less ubiquitous variety, the Midland Hawthorn, which is the true English species of this tree. I have been on a quest to find an example of it in our local area for about five years now, but, throughout that time, my search has been hampered by one small technical problem: I didn’t really know what made it discernibly different. Tree guides waffle on confusingly about leaf shape: the Midland’s leaves are less deeply cut than the Common, the Midland’s lobes are more forward pointing; but try looking at the leaves on just one Common Hawthorn and they are so variable throughout the tree that one could be looking at either species.
However, armed with a new differentiation strategy I have now identified one Midland Hawthorn(1) in a local meadow. From a distance of about three feet the tree is virtually impossible to tell apart from the Common Hawthorns in the same hedgerow, but get up close, examine a flower and the difference becomes apparent. Common Hawthorn has just one green style amidst the stamens in its flower, while Midland Hawthorn has two, or possibly three. On examination the leaf shape of this tree is as described in the tree guides, but it would be very difficult to identify the tree on that basis alone.

So, to my great delight, after years searching, I have found my Midland Hawthorn, right here in a meadow behind my home. Why does it matter? Those who have to ask may never understand, but for the amateur naturalist such quests are the learning journeys which make life and the natural world that little bit more interesting. Furthermore, the Midland Hawthorn is hugely significant in our history: its flower is the Mayflower, for centuries the very emblem of May in rural England. It symbolises hope and new beginning. In the superstitious times of the 17th century, many ships were called Mayflower, but it turned out to be a wonderfully apt name for a little ship sailing out into the New World in 1620 with a group of pilgrims on their own journey of hope, personal development and new beginning.
