114 CLASS IC0SANDR1A. 



lals, with an inferior, 5-cleft, hispid or bristly calyx ; 

 7 to 20 stamens ; and only 2 hard coated seeds in the 

 bottom of the calyx. 



In Pyrus, the genus of the Apple and Pear, of the 

 section Pomaces, in the Rosaceous order, the calyx 

 is 5 cleft ; the petals 5 ; the Apple inferior, or crown- 

 ed by the calyx, large, and of a fleshy or solid consis- 

 tence, including a 5-celled, few seeded capsule ; the 

 seeds themselves furnished with a cartilaginous coating. 

 The P. coronaria, or Native Crab, is remarkable for 

 the beauty of its somewhat fragrant blossoms, and 

 the leaves, instead of being entire, have often an evi- 

 dent tendency to lobing. The Apple or Crab of this 

 species, when ripe, is almost diaphanous, entirely yel- 

 low, and on mellowing becomes very fragrant ; it has 

 also scarcely any depression at the insertion of the 

 stalk. 



The genus Aronia, or Shad-blossom, as it is called 

 in New-England, is the same with the Amelanchior 

 of Europe, and scarcely different from Pyrus, having 

 the same kind of seed, inclosed, however, in a berry, 

 rather than an apple, with 5 to 10 cells, the cells 1 to 

 2-seeded. These form one of the prominent orna- 

 ments of our forests, about the month of May, when 

 the branches appear as if loaded with clusters of white 

 fringe, from the narrowness of the petals. They come 

 out likewise before the full developement of the leaves, 

 and are disposed in racemes or corymbs. 



In Polygynia, of the Icosandrous class, you will 

 find the Rose (Rosa), so long and deservedly celebrat- 

 ed for its beauty, variety, and fragrance. The calyx, 

 in the form of a pitcher, or urceolate, contracted at 

 its orifice, and terminating above in a deciduous 5- 

 cleft border, is the peculiar and most distinguishing- 

 trait of the genus. The 5 petals are remarkable for 

 their great size and fine color. The seeds, very nu-
