LINN^JAN SYSTEM. 101 



18. POLYDE'LPHIA (from the Greek, poZus, many, and delphos) : 

 having the filaments of the stamens united into more than 

 two sets. 



19. SYNGENE'SIA (from the Greek, 'sun, together, and geinomai, 

 to arise, to grow) : having the stamens united by their 

 anthers in a ring or tube, as in the sunflower. 



20. GYNA'NDRIA (from the Greek, gune, woman, used meta- 

 phorically for pistil, and oner, stamen) : having the stamens, 

 in appearance, growing out of the pistil, as in the ladies' 

 slipper. 



In all the preceding classes the flowers are perfect. 



11. The next three classes are characterized by the stamens 

 and pistils being separately contained in different flowers. 



21. MONCE'CIA (from the Greek, monos, single, and oikia, 

 house) : the stamens and pistils are in separate flowers, but 

 both grow on the samo plant, or both dwell in the same 

 house, as the name denotes. 



22. DICE'CIA (from the Greek, dis, two, and oikia") : the stamens 

 and pistils are not only in separate flowers, but on different 

 individuals, they are in two households. 



23. POLYGA'MIA (from the Greek, polus, many, and games, 

 marriage or union) : the stamens and pistils are separate 

 in some flowers, and united in others, all on the same, or 

 on two or three individuals of the same species. 



12. The last class includes flowers in which neither stamens 

 nor pistils are visible. They are now termed flowerless plants. 



24. CRYPTOGA'MIA (from the Greek, kruptos, concealed, and 

 gamos, marriage) : having the essential organs of the flower 

 concealed from view. 



A synoptical view of the Linnsean classes is seen in the 

 following : 



What are the characters of Syngenesia ? What are the characters of 

 Gynandria? 



11. What are the characters of Moncecia ? What are the characters of 

 Dicecia ? What are the characters of Pol ygamia ? 



12. What are the characters of the class Cryptoga'mia ?
