The fruits of the Spanish needles (c), of Hedysarum (b,j), and of the cockle- bur (to) attach themselves to passing animals.' The sepals of Salvia glu- linosa, surrounding the ripe fruits (/), bear sticky glandular hairs which adhere to objects that they touch, as shown at k. When the germander plant (b) is shaken, the fruits are discharged by a mechanism composed of the sepals and the elastic pedicel. The fruits of Mgilops (0) and of Crupina (p) creep by means of the hygroscopic movements of hairs and other parts.
