In general, between the toxic and stimulative concentrations there is the gradation of the former into the latter. This gradation may properly be called "toleration". (See plate 1.)Publication Rust of antirrhinum(1917) Doran, William LeonardThe cultivated snapdragon ( Antirrhinum majus 3 .) is a perennial or biennial under culture, it is a member of the family Scrophulariaceae. The plant was introduced here from Europe. As an escape from gardens, it is rare in New England. The snapdragon has been a popular garden flower for two hundred years, but it is only within the last ten years that it has been grown to any extent as a greenhouse crop. There has been an increasing demand for it as a cut flower, and consequently an increasing amount of glass has been devoted to its culture. As a florist's crop, the snapdragon may be classed as about equal in importance to mignonette, schizanthus, stocks, pansies, and primulas (Nehrling, 1914), varying, of course, in different localities.
