(From cotton, and, grass; from the softness of its texture). See Panicum. Linaria, (from the resemblance of its leaves to those of flax,) osiris urinaria, flax weed, or common toad flax, antirrhinum linaria Lin. Sp. Pl. 858. The common sort resembles the esula minor so closely, that it cannot be distinguished before the flowers appear but by breaking the stalk, as the toad flax is destitute of the milky juice. It is perennial, grows wild about the side of dry fields, and flowers in June and July. If the leaves, which are bitterish, and of a saline taste, resembling in smell, when rubbed, the elder, are inwardly used, they are diuretic and purgative and particularly powerful in the latter view. The plant has been supposed also an aperient and deobstruent, and used in jaundice. Externally they have been commended against the piles. A name also for a species of elychrysum. Linaria Hederaceo Folio. See Cymbalaria.
