114 THE KOBE. 



Analysis. We have in hand a slirub, with woody stems, 



4 to 6 feet high your own stature more or less. It is 

 beset with prickles. Mark their structure ; compare them 

 with the thorns of the thorn-apple, and note how they 

 differ. 



The leaves are odd-pinnate, consisting of 5 to 9 (an odd 

 number) elliptical, serrate leaflets, with pinnate and reticu- 

 late veins. The 2 narrow stipules are adnate to the petiole. 



The Inflorescence is in the form of a corymb the 

 peduncle branching into unequal pedicels bearing the flow- 

 ers at about the same level. 



The Flower may be cut vertically (1) for a better view 

 of the structure. The calyx tube is seen inclosing, but not 

 adhering to the 15 20 distinct, inferior (?) ovaries. The 



5 sepals are some or all of them tipped with a leaflet. The 5 

 quincuncial, broad-ohcordate, rose-colored petals are inserted 

 with the oo perigynous stamens on the calyx tube. 



The Fruit, generally called a hip (5, 6), is globular, 

 fleshy, red, inclosing (not adhering to) the 15 or more dis- 

 tinct bony achenia. The styles are persistent (3, 4). The 

 seed is anatropous, suspended from the upper part of the 

 cell (7, 8). 



THE DOUBLE KOSE. In wild native plants double flower- 

 ing is extremely rare. Have you ever known an instance ? 

 This phenomenon seems to be an unnatural condition 

 induced and perpetuated by the art of the cultivator. Its 

 study reveals many secrets of nature's laws. In any col- 

 lection of Roses we find some single and natural, some semi- 

 double, and some fully double. The 1st exhibits a corolla of 

 5 broad, equal petals, and a great number of stamens within 

 its enclosure. The 2d displays a 5-petaled corolla with 20 or 

 more narrow petals superadded, and in their midst a dimin- 

 ished number of stamens. The 3d shows a hundred petals
