viz. monogynia, digynia and trigynia; all derived from 

 the number of pistils in each flower. 



10. Monogynia: Comprehending such plants of the 

 class, as have flowers with but one pistil. 



Among the plants in this order, are the jasmine, privet, olive, lilac, 

 enchanter's night-shade, speedwell, hedge-hyssop, butter-wort, 

 water-horehound, sage, and many others. 



11. Digynia: Including such plants of the class, 

 as have flowers with two pistils. 



This order consists only of the two genera, vernal grass and 

 crypsis. The sweet-scented vernal grass is the only indigenous plant. 



12. Trigynia: Embracing such plants of the second 

 class, as have flowers with three pistils. 



The genus piper or pepper, is the only family of plants at present 

 known of this class and order. In this genus, there is neither caljx 

 or corolla. 



CLASS III. TRIANDRIA. 



13. Character: The third class includes those plants 

 which bear flowers with three stamens. (F. 170.) 



This is, in various respects, a natural class. Iris, crocus, morsea, 

 antholyza, corn-flag or sword-lily, ixia, and some others, have con- 

 siderable affinities to each other: they, together with commelina, 

 spider-wort, pontederia, &c. constitute Linnaeus's sixth natural order 

 called tnsatce. 



14. Division: There are three orders of plants in 

 this class: viz. monogynia, digynia, and trigynia; all 

 established from the number of pistils in each flower.
