united, the pistil. These pistils rise from the 

 germs; which, when fecundated by the dis- 

 charge of the pollen upon the stigma of the 

 flower, become the seeds. 



The part of the corolla which secretes the 

 honey, is called the nectary. 



The rose, while still a bud, is protected by 

 several long green leaves of a pointed form, 

 which constitute the calyx, or flower-cup ; the 

 subdivisions being named sepals. These spring 

 from the pericarp, or seed-vessel, contained in 

 the tube of the calyx, which, in a state of 

 maturity, varies in colour from green to red, 

 and constitutes the fruit. 



The calyx is mounted on a short stem, which 

 is called the peduncle, or flower-stalk; when 

 consisting of many stems, to form a cluster, 

 these subdivisions are called pedicelli. 



To the flower-stalk, or peduncle, are usually 

 appended small leaflets, called bracteal or floral 

 leaves ; the petioles, or leaf-stalks, having still 

 smaller leafy appendages, called stipules. 



A ligneous plant, or shrub, such as the rose, 

 is divided into the trunk or stem, branches, and 

 sprays or branchlets. 



The leaf of the rose is composed of three,

 foot-stalk ; each leaflet being supported by a 

 secondary foot-stalk. 



The stems and stalks are often clothed with
