-206 FORMS OF THE COROLLA. 



\y smaller than the others, as in Biitomiis^ t, 651, or 

 otherwise different, as in Aquilegia. t. 297. It is by 

 no means always necessary, in defining characters of 

 genera, to use these last terms, it being sufficient in 

 general to say that a Corolla is regular in opposition 

 to one that is irregular ; more especially as some 

 species of a genus may possibly have an equal corolla, 

 others an unequal one. 



The most usual shapes of a monopetalous corolla 

 arc 



campanulata^f. 159, bell-shaped, as in Campanula, 1. 12. 



infundibuliformis, f. 160, funnel-shaped, (102) Pulmo- 

 naria, t. 118. 



kypocrateriformis, f. 155, salver-shaped, (103) Pri- 

 mula, t. 4. 



rotata, wheel-shaped, that is salver-shaped with scarce- 

 ly any tube, Borago, if. 36. 



ringens, f. 161, ringent, irregular and gaping like tlie 

 mouth of an animal, Lamium, t. 768 ; called by for- 

 mer botanists /a6?a?«, lipped. (104) 



personata,/. 162, personate, irregular and closed by a 

 kind of palate, Antirrhinum, t. 129. Those of a 

 polypetalous one are 



cruciformis, f. 156, cruciform, regular and like a cross, 

 Bentaria, t. 309, and Cheiranthus, t. 462. 



(102) [Tubular at bottom, but gradually expanding toward the 

 top, as Thorn Apple, Daturar\^ 



(103) [Tubular for nnost of its length, but suddenly expanding 

 into a flat border at top.] 



(104) [The upper lip of a ringent coroUais commonly smaller, 

 and has the stamens projecting from beneath it. The lower lip 

 is larger and more expanded. When this order is changed, the 

 corolla is said to be reversed.']
