In wall-flower (Cheiranthus cheiri, L.) a curious floral abnormality has long been known. The plant is quite normal until it blooms. In the flower, however, while the sepals are normal the petals are reduced to narrow strips equal in length to the sepals or slightly shorter. The stamens are as usual six in number, but adhere together, forming a closed ring round about the normal ovary. De Candolle describes the abnormal as a distinct variety under the name Cheiranthus; cheiri gynanthus. How far this is valid may be questioned, as the abnormal can only set seed when pollinated from the normal hermaphrodite, and is, therefore, not self perpetuating. A number of somewhat similar aberrations are known in other species, such as The Opium Poppy (Papaver somniferum). Includes plates.
