Abstract
ALL the flowers of the ground ivy (Nepeta Glechoma) that I have this season examined, from this neighbourhood, have been of the stamenless form described by your correspondent “S. S. D.” While spending a few days at Bath, I could find none but hermaphrodite flowers. At Hertford I found both forms, but a preponderance of hermaphrodites. These seem always more or less protandrous, and spontaneous self-pollenation is further prevented by the unequal lengths of the style and stamens.
