called Brodicea. 5 



the Brodicece, used the word hractece instead of spat/ice^ as more 

 agreeable to nature. 



Tliese difficulties do not trouble the generality of practical 

 botanists ; but theoretical ones, before they can found new ge- 

 nera, or even understand the old ones to any purpose, are, and 

 always have been, obliged to consider them, and may be 

 glad of any suggestions on subjects concerning which the chief 

 leaders in botany have never agreed together, nor scarcely 

 been consistent with themselves. I am persuaded the line of 

 discrimination betwixt a calyx and corolla is, in many cases, not 

 to be drawn, for this plain reason, that Nature in such cases 

 unites both the parts into one, the inner surface performing the 

 functions of a corolla, the outer those of a calyx. This is a 

 suggestion of Linnaeus, but he has not illustrated it so fully as 

 it deserves. I need not repeat here what is already before the 

 public in another place, Introduction to Botany, 264, 266, and 

 267; nor shall I now add any thing more than a wish, that a 

 subject so interesting to the physiological as well as the systema- 

 tical botanist might be pursued by both to their mutual as- 

 sistance.
