Ajuga reptans – 'Bugle'. Family Labiatae. A deep purple blue flower amongst leaves that are a deep blue green to pruple, all growing together in a spike, commonly found on woodland floors. Godin considers it likely that Bugle survived in refuges in the UK through the last glaciation.
Entomphilous, pollen is not profuse and probably stays fairly local.
Pollen grains 2 nucleate, 3 (or 4) colpate. Grains longer than broad (oblate, prolate), less than 40 microns in length. Reticulate, colpi covered by membrane with granules upon it.
