OBs. The principal differences between this plant and the following, are, that the capsules of this are so deeply and acutely three-sided, as to appear three-winged; the flowers pearly black, and the leaves sulcated underneath, and ciliated at the margins: while those of the following have obtusely three-sided capsules, purple flowers, and the leaves not furrowed underneath, nor ciliated at their margins.
