A CAUSE OF CONFUSION. 229 



the Scrophulariaceae is easily distinguished from that of 

 the Labiatse. 



In some corollas, the two lips are hollowed out in a 

 very singular fashion, as in the Calceolaria; assuming a 

 " slipper-like appearance," similar to what takes place in the 

 labellum of certain orchids, to wit, the Cypripedium. These 

 calceolate (calceolus, a slipper) corollas may be looked upon as 

 consisting of two slipper-like lips. 



The forms of the bilabiate, tubular, and ligulose florets, 

 of the capitula of the Synantherae, are likewise due to simple 

 differences of union. The floscular capitulum comprises the 

 tubular florets, and the semi-floscular capitulum, the ligulate 

 florets; the radiate capitulum consists of florets ligulate or 

 bilabiate at the circumference, and of tubular florets over the 

 rest of the receptacle. By considering the capitula, as the 

 vulgar do, to be flowers, Tournefort introduced considerable 

 confusion into the nomenclature of the Synantherae. 



SUMMER FLOWERS. 

 *' Dawn, gentle flower, 



From the morning earth ! 

 We will gaze and wonder 

 At thy wondrous birth 1 



" Bloom, gentle flower, 

 Lover of the light, 

 Sought by wind and shower, 

 f ondled by the night ! " *
