312] or perianth, being seldom found in a double or multiplied state, is the next part of a flower that is liable to the least changes; and may, therefore, on accurate inspection, serve to detect the genera of many duobledouble [sic] flowers.

With respect to the colours which may be extracted from flowers, we refer the reader to the article, p. 38, and to the different flowers as they occur in their alphabetical order.  FLOWER-DE-LUCE, or, Iris, L. a genus of plants consisting of 54 species, the following three of which are natives of Britain:

1. The pseudacorous,, or Yellow Flag; which is perennial, grows on the banks of rivers, in marshes and wet meadows, and produces large yellow flowers in the month of July. The leaves of this plant, when fresh, are eaten by goats, and when in a dry state, by cows, but they are refused by horses and hogs.—On account of its poisonous nature to all cattle, except sheep, this vegetable ought to be carefully extirpated from meadow-grounds, and their contiguous ditches. The juice of the fresh root is very acrid, and has been found to produce plentiful evacuations from the bowels after other powerful remedies had failed: by continuing its use, it cured an obstinate dropsy. For this purpose, it has been taken in doses of 80 drops, every second or third hour; but the degree of its acrimony is so uncertain, that it can never be generally used.—With more advantage and safety we may recommend the whole of this strongly astringenent plant to the '; and its flowers to the ', for extracting a beautiful yellow; but the root, in particular, as a substitute for galls in preparing a black dye, or ink, with vitriol of iron.—Lastly, the roots of this species are stated to be an antidote to the ; and, after having been mixed with the food of some hogs that had been bitten, they escaped the disease, while others, injured by the same dog, died raving mad.

2. The fœtida,, Gladwyn, or Flag, which is found on hedge-banks, and sloping grounds, particularly in the south-western counties of England: it is perennial, and produces flowers of a purplish ash-colour, which lose their smell during the night, and blow in the months of June and July.—This plant is refused by horses, sheep, and goats; its leaves are very fetid, and, when bruised, smell like rancid bacon. The juice of the roots of this, as well as the preceding species, have occasionally been used to excite sneezing; which is a dangerous practice, and has sometimes been attended with violent convulsions. It may, therefore, be more usefully employed for the destruction of bugs and other vermin.

3. The Xiphium, or, or Flag, which has long been cultivated in our gardens, on account of its beauty. It has lately been found wild in the county of Worcester, and produces generally purplish-blue flowers.—M. informs us, in his "Social Narratives" (in German), that he made the following experiments with the azure-blue flowers of this neglected plant: He first bruised the flower-leaves in a marble mortar, expressed their juice, collected it in a shallow glass vessel, and, after  ing
