The fer- tilising bodies or pollinoids are naked masses of protoplasm, of a spheri- cal or elongated form, sometimes with a beak-like appendage, and are discharged in succession one after another. They are carried along passively by the water, and are distinguished from the antherozoids of other Cryptogams by the absence of cilia, and, in most cases, of any spontaneous power of motion.
