132 I.INN/EAN ARTIFICIAL SYSTEM. 



ment of plants, and subdivided into four orders; viz. 

 monogynia, digynia, trigynia, and tetragynia ; all derived 

 from the number of pistils in each flower. 



46. Monogynia : Including every plant of the octan- 

 drous character, with one pistil in each flower. 



Many plants present themselves as of this order, among which the 

 well known tropaeolum or nasturtium of our gardens, the different 

 willow-herbs, blackbery, bilberry, mezereon, are familiar specimens. 

 The heaths of this country, together with upwards of three hundred 

 native species of the Cape of Good Hope, and a few more of other 

 countries, form the major part of the order, as the largest genus of 

 plants at present known. 



47. Digynia .-Including every plant of the eighth 

 class, with two pistils in each flower. 



This is a small order of few plants hut little known ; among which 

 is the African galenia, a native of the Cape of Good Hope, and the 

 mossy moehringia, a perennial plant of the south of Europe. 



48. Trigynia: Comprising all plants of the octan- 

 drotis character, with three pistils in each flower. 



The principal genus of this order is the polygonum or persicaria, of 

 which the well known bistort or snake-weed, and the water-pepper, 

 are species. The soap-berry, heart-seed, sea-side-grape, seriana, 

 and paullinia, are other genera of the same order. 



49. Tetragynia: Embracing every plant of the oc- 

 tandrous character, with four pistils in each flower. 



In this subdivision we find the trne-love or herb-parish, and the 

 tuberous moschatel, both native perennials of this country.
