Dictamnus fraxinella, - Red Fraxinella, - an ancient name of what is now supposed to be the Origanum dictamnus. Fraxinella, in allusion to the remarkable similarity which exists between the leaves of the plant and Fraxinus, the ash. The whole plant, especially when gently rubbed, emits an odor like that of the lemon-peel, but, when bruised, has something of a balsamic scent. This fine scent is strongest in the pedicels of the flowers, which are covered with glands, of a rusty red color, exuding a viscous juice, or resin which exhales in vapor, and in a dark place may be seen to take fire. It flowers from May to July; three feet high; from Germany. There is also a variety of species with white flowers; propagated by parting the roots.
