Tower-Mustard, the Smooth, or Tower-wort, Turritis glabra, L. is an indigenous plant growing in gravelly meadows, pastures, and pits, where the stalks attain the height of two feet, and the greenish-white, large flowers appear in May and June. - The taste of this vegetable resem- bles that of cresses; and, affording wholesome food for cattle, we conceive it deserves the attention of cultivators, in the northern parts of the island, which abound with dry, stony lands and pastures. Farther, the flowers of the tower-wort supply the industrious bee with wax and honey.
