SWARM-CELL, see Zoospore. 



SWARM'ING, moving about by 

 meiins of cilia — said of zoo- 

 spores. Chiefly used when

 within a liquid in any definite 

 manner. Compare Natant. 

 The swimming of zoospores 

 when massed, however, is

SWORD' SHAPED, see Ensiform, 



SYCHNOCAR'POUS, see Polycar-

 mutualism; mutual parasitism; 

 commensalism; cousortism. 

 With some authors Commen- 

 salism implies an association 

 less necessary or mutually 

 helpful tban Symbiosis. 



SYMMETRICAL, (1) having se- 

 pals, petals, and stamens of 

 the same number, or multiples

 halves, which are similar to, 



or the reflections of, each 

 other. See Monosymmetri- 



CAL and PoLYSYMMETRICAL.

 alous. Also formerly used 

 for a partial union of the pet- 

 als with monadelphous sta- 

 mens, as in Malvaceae.
