This variety of the Rose is a native of the United States, and 
is found in various parts of the country, from Maine to Carolina, 
inhabiting the declivities of hills and rocky places. The calyx with 
the tube is contracted at the mouth, with a five-parted limb ; the 
segments are somewhat spirally imbricated at the apex in aestivation, 
and are usually pinnately divided, and numerous ; the carpels are 
numerous, bony, inserted on the inside of the tube of the calyx, 
which at length becomes baccate, and encloses them ; they are dry 
and indehiscent, bearing each a style on the inner side ; styles exser- 
ted from the constricted part of the calycine tube, sometimes distinct, 
sometimes collected into a columnar style ; seeds solitary, exalbumi- 
nous, inverted ; embryo straight, with flattish cotyledons. 
The Pose is known by almost every person at first sight, and 
has been a favorite flower from time immemorial among the civilized 
nations of both continents. The shrub varies in size in different 
species and varieties, and the colors are red, white, purple, yellow,
