Duckweeds multiplylargely by budding, and the parent plantand offsets often clin^ together in clus-ters. Individual plants vary in size fromone-twelfth to three-fourths of an inchin diameter. Two genera of duckweeds lack of these {Wolffia, fig. 2, e, f), con-tains the smallest flowering appear as green granules, onetwenty-fourth of an inch or less in diam- 114 THE GAME BREEDER. Fig. 2.—Duckweeds: a, b, Spirodela; c, d, Lerrma: e, f, Wolffia: g, h,Wolfflella, eter, and are often abundant among otherduckweeds or about the margins of lakesand ponds. When the hand is dippedinto the water large numbers of theplants adhere to it. They look likecoarse meal, except for their green color,and feel like it, so that a good name forthem would be water meal. The other genus of rootless duck-weeds {Wolffiella) consists of strap-shaped plants (fig. 2, g, h), narrowed atone or both ends. They are from one-fifth to three-fifths of an inch in lengthand commonly cohere in radiate bodiesor in large masses of less definite struc-ture. Duckweeds are known also as ducksmeat, water lentils, and seed moss. Thelatter term, in fact, is used in Arkansasto cover all components of the vegeta-tion of the water surface. Besides duck- weeds, this mass includes that green orred, velvety, mosslike plant, Azolla caro-liniana, and the branching straplike liver-worts, Ricci
