THE FLOWER. 



Wheel-formed, Fig. 112, (Rotate,) having 

 the form of a wheel ; the limb of the corolla 

 spreading with a very short, or no percepti- 

 ble tube. The Fifth Class presents many 

 examples of this kind of corolla. Ex. Bor- 

 age, (Borago,) Red Pepper, (Capsicum,) 

 Loose-strife, (Lysimachia.) 



Fig. 112. 



Labiate, Fig. 113, or (Ringent,) irregu- 

 lar, and gaping like the mouth of an ani- 

 mal. It consists of a single petal divided 

 obliquely into two irregular parts, called 

 the upper and lower lips, a, b. When 

 the lips are widely separated, it is called 

 ringent. When the lips are closed by 

 an appendage or kind of palate, it is called a personate co- 

 rolla, from persona, a mask. Ex. Sage, (Salvia.) Lavender, 

 (Lavendula,) Catnep, (Nepeta.) 



It is a circumstance worthy of notice, that this tribe o( 

 plants, with few exceptions, are either tonic, aromatic, 01 

 cordial in their qualities. Several of them, as Sage and Lav- 

 ender, contain considerable quantities of camphor. 



Fig. 114. 



Salver-shaped, Fig. 114. (Hypocrateri- 

 forrn.) Having the border spread out hori- 

 zontally, and ending in a tube. Ex. Prim- 

 rose, (Primula.) Narrow leaved Laurel, 

 (Kalmia angustifolia,) Lichnidia, (Phlox.) 



POLYPETALOUS COROLLAS. 



Any corolla composed of more than one petal, is termed 

 polypetalous. 



Fig. 115. 



The petals or polypetalous corollas, consist of an 

 elongated, or long narrow part, f, called the claw, 

 and by which it is attached to the calyx, and an 

 expanded and commonly more highly colored por- 

 tion, a, called the border. 



What is the form of a rotate corolla ? Give an example of a labiate 

 corolla ? How is the salver-shaped corolla described ? In the polypeta- 

 lous corolla, which is the claw, and which the border ?
