174 FLOWER. 



coloured leaf as in Stramonium, or is polypetalous being 

 composed of several as in the Pond Lilies and Magno- 

 lia. In the former case, we find the tube, the orifice, 

 and the border ; in the latter, the claw by which the 

 petal is attached to the receptacle, and the border, 

 which corresponds to the expansion of the monopeta- 

 lous corolla. In either case, we find flowers that are 

 'regular, Figs. 76 and 77, the petals being equal in size 

 and similar in form ; flowers that are unequal, the pe- 

 tals being similar, but of different sizes ; and flowers 

 that are irregular, Figs. 79 and 81, the petals or their 

 segments being unequal and dissimilar. The tube is 

 long and slender, as in the sweet-scented Mirabilis, or 

 it is twisted as in Periwincle ; the throat is closed as 

 Borage and Comfrey, or it is naked as in Gromwell, and 

 the border or limb is plaited, as in Convolvulus, and re- 

 flected as in the Lilies. Petals furnished with a claw 

 as in the Pink and wall flower, are said to be renguicu- 

 late. 



A monopetalous corolla is, 



Campanulate or bell-shaped as in the Bell-flowers. 



Funnel-shaped as in the Stramonium. 



Ovate as in Uva-ursi and Partridge berry. 



Urceolate or Pitcher shaped, as in Whortle-berry. 



Salver-shaped, having a slender tube and flat border, 

 as in Moss Pink and Lichnidia. 



Rotate or wheel shaped, as in Loose strife and 

 Borage. 



Tubular as in Fever-root and Trumpet Honeysuc- 

 kle. In the Rotate corolla, the tube, if present, is very 

 short, and in the tubular corolla, there is a deficiency 

 of the border. 



Labiate or Ringent, Fig. 81, when the segments are 

 irregular resembling the lips of an animal. If these
