Arrow-root (Maranta Arundinacea) is the name the Indians of America gave this plant. In German arrow-root is called pfeilwurz, pfeil meaning arrow, and wurz meaning root. It is the English name of the botanical genus maranta, the type of the endogenous order Marantacea, called by Lindley in his "Natural System of Botany" the arrow-root tribe, but altered in his "Vegetable Kingdom" to maranta.The flowers of this plant are in long, close spikelike panicles with irregular corollas, each having a single perfect stamen with half another. The veins of the leaves run out obliquely from the midrib to the margin. The root is a fleshy corm which when washed, grated and strained, and again repeatedly washed, furnishes the substance so much prized as food for invalids.The starch extracted from the rhizomes of different maranta, and imported into the United States and England, takes the name of the place
