In southwest Buckinghamshire within the Chilterns,
Homefield Wood contains a mix of beech and spruce plantations plus fragments of natural woodland, with other trees including whitebeam, sycamore, yew, laurel and ash, extending over gently-sloping land either side of a shallow valley. The wood has been modified by forestry operations for at least the last 200 years, though a few more ancient trees survive, and the chalky soils support an unusually wide range of wildflowers, in particular orchids, some such as
fly orchid and
white helleborine in the deep shade beneath the trees, and others in the small patches of open grassland, and of these, by far the most uncommon is the
military orchid,
orchis militaris, which although quite widespread in western Europe is in the UK found (naturally) at only two other sites, both in Suffolk.
The orchids at Homefield Wood are protected both as a nature reserve and a Site of Special Scientific Interest, occupying just one small section of the woodland along its eastern edge, accessed by a minor road 5 miles northeast of Henley-on-Thames. One other particularly rare and beautiful wildflower found here is the
Chiltern gentian, while six other orchids are
bee,
common spotted,
fragrant,
greater butterfly,
broad-leaved helleborine and
common twayblade.
