THE FLOWER. 3M 



plants the foot-stalks of the leaves perform the office ot 

 tendrils, as in the common Nasturtion, and Virgin's bower, 

 (Clematis cirrhosa.) 



Gland, Fig. 93. This is a small 

 tumor which discharges a fluid that is 

 eilher resinous, oily, or saccharine. It 

 is situated on various parts, as on the 

 back of the leaf, on the petiole, or 

 sometimes between the notches of 

 the leaves. Some glands are raised 

 from the surface by little foot-stalks, 

 as at g in the figure where they are 

 situated on the petiole, and appear 

 like small tubercles. Others are 

 hardly raised above the surface, appearing like dots, scales, 

 or minute bladders, as in the leaves of the Plum, and Peach 

 The Moss rose owes its peculiarity of appearance, about the 

 calyx and flower-stalk, to its glands. 



Pubescence. This term includes the clothing of plants, 

 such as Hair, Wool, Bristles, Stings, &c. These slight ap- 

 pendages differ considerably from each other in form, soft- 

 ness, color, and other particulars. Their individual names 

 are taken from some well known substance, or thing which 

 they are supposed most nearly to resemble. Thus the cloth- 

 ing of the Mullein is woolly ; that of the Primula villosa, is 

 velvety ; that on the under side of the Colt's foot, ( Tussilago,) 

 is downy ; while that of the common Nettle is prickly. 



THE FLOWER. 



Having described the different parts of a plant from the 

 root upward, we come now to describe the flower. This 

 part, which is the chief object of culture to the florist, is 

 equally important to the scientific Botanist, since on it de- 

 pends the distinction, and systematic arrangement of the plant 

 o which it belongs. 



What are the glands of plants ? What are the appearances of glands, 

 ar d where are they situated ? On what account is the flower of iinpor 

 taice'to the Botanist ?
