CLASS DECANDRIA. Id? 



Somewhat allied to this genus is the Pyrola, or 

 Winter-green, of which there are several species both 

 in the United States and northern Europe. These 

 grow commonly in clusters, in shady Fir woods, have 

 running roots, and dark green, sempervirent leaves, 

 generally roundish or oblong, from which arise low 

 scapes, bearing 1, or many, sometimes fragrant, 

 whitish flowers disposed in racemes. These consist, 

 according to the genus, of a small 5-cleft calyx ; and 

 5 petals slightly united at the base. The stamina 

 open with 2 pores, and the anthers become reversed. 

 The capsule is 5-celled, and 5-valved ; and the seeds 

 very small and numerous, are, as in the preceding 

 genus, invested with a long arillus. The most com- 

 mon species is the P. rotundifolia, flowering about 

 July or August. The leaves of a thick consistence, 

 are rounded or dilated oval, obsoletely serrulate on 

 the margin, with the petiole about as long as the lami- 

 na of the leaf; the scape many flowered, and the style 

 declinate or inclined downwards. 



The Chimaphila or Pipsisseway, formerly referred 

 to Pyrola, is a genus of evergreen plants with running 

 roots, and oblong lanceolate leaves clustered at different 

 distances along the stem, from the bosom of which 

 arise pedunculated umbels of a few white or reddish 

 flowers, constructed much like Pyrola, but with the 

 filaments arising from as many round margined disks, 

 and the germ destitute of any distinct style. 



In the second order, or Digynia, you will find the 

 genus Dianthus or Pink, being the type of the natural 

 order Caryophylle^:. In this genus is included, 

 besides the Pink of our gardens, the China Pink, 

 Sweet William, and the small flowered Sand Pink 

 (D. armeria). In this genus the calyx is 1-leaved, 

 and tubular, with the border 5-tootheci, its base com- 

 monly subtended by about 4 imbricate opposite scales.
