and appearance of its berry, from which an agreeable wine ia 

 said to be prepared in Corsica. The Rhododendrons, Azaleas, 

 and Kalmias, however, possess more active properties than the 

 rest, and are decidedly poisonous to Man. The honey which ia 

 made from their flowers has proved extremely deleterious to 

 those who have eaten of it ; and it has been said that the flesh 

 of Birds, that have fed on the buds of the Kalmia, becomes 

 alike injurious. 



643. The following tabular arrangement of the chief British 

 orders that have been described in this sub-class, will assist the 

 student in distinguishing them. 



SUB-CLASS II.-^-CALYCIFLOR^E. 



Sepals of calyx adherent into a cup or tube. Calyx united to 

 the disk. Petals and stamens apparently springing from the 

 calyx. 



A. Petals of corolla distinct, or nearly so. 



a, Carpels distinct, or but slightly adherent, 



each having its style and stigina. 

 a, With stipules. 



Carpels numerous .... Rosacece, 593 



Carpels solitary . . . . Leguminosce, 586 



j8, Without stipules. 



Vegetation succulent . . . Crassulace<E t 609 

 Vegetation not succulent . . . Saxifragete, 615 



b, Carpels completely united. 



a t Ovary superior. 



Stamens opposite the petals . . Rhamnece, 583 



Stamens alternate with the petals . . Celastrinea, 582 

 )8, Ovary inferior. 



Ovary 1 -celled .... Grossulareee, 613 

 Ovary 2-celled .... Umbelliferce, 617 



Ovary 4-celled .... Onagrariacece, 599 

 B.* Petals cohering into a tube, to a greater or less extent. 

 a, Ovary inferior. 



* This division, with the exception of Cucurbitacese, is placed by many Bota- 

 nists who adopt De Candolle's system, in the next class. With the exception of 

 the last order, Ericineae, which is easily distinguished from all others, oy the 

 mode of opening of its anthers, they are at once known from the Monopetalous 

 orders of the next sub-class, by their inferior ovarium.
