Io6 SWARZ ON THE GENERA OF ORCHIDEjE, 



rent on the other side with the style, and considers 

 both these parts of the nectary), calls that small 

 part, which is situated upon the style, either fixed 

 or moveably, labium suberius ; the two apertures 

 or loculaments of which he describes as a duplica- 

 iura bilocularis, formed by the same upper lip for 

 the covering of the pollen- masses contained within, 

 and to which he gave the name of Anthers. 



This part is no more deserving the name of 

 labium mperius neciarii than that of labium supe- 

 rius corolla. Of all the Orchideas yet known to 

 me, Cypripedium bulbosum Linn, is the only one 

 which really has such an upper lip fixed to the 

 base of the style, and opposite the upper leaf of the 

 calyx. To discover the real use of this pretended 

 upper lip, we have only to observe its structure 

 and insertions, and that it is often deciduous, par- 

 ticularly in the Indian and Cape genera. We see 

 that it is nearly wanting in the genus Corycium, 

 where the anther, in. form of a saccus didymus, is 

 situated beneath the lip itself, and at the sides of 

 the style nearly as in Cypripedium calceolus, which 

 on the other hand has two very distinct bilocuku*
