stalked appendage, whose stalk is occasionally irrita- 

 ble at it's joint." Broion. The Stamens, according 

 to this able observer, consist of 3 Filaments, com- 

 bined together, as well as more or less united to the 

 Style, within the upper Calyx-leaf, opposite to the 

 Lip ; the 2 lateral ones almost always abortive, and 

 generally short, or obsolete, the intermediate one only 

 bearing an Anther. In Cypripedium alone, as far as 

 hitherto observed, the latter only is abortive, both the 

 side ones being antheriferous. Anther of 2 cells, 

 which are either separate, and fixed to the sides of 

 the Column (or Style), often extending beyond them; 

 or brought together into a simple Anther, either 

 parallel to the Stigma, immoveable and permanent, 

 fig. 71, e, or terminating the Column in the form of a 

 generally moveable, deciduous lid, fig. 77 and 78, a; 

 each cell being divided internally by one, seldom three, 

 longitudinal partitions. The Pollen consists either of 

 simple grains, or frequently of fourfold globules, col- 

 lected into masses fitting the cells; these in the fixed 

 divided Anther, fig. 71, e, rarely in the terminal move- 

 able one, fig. 77, 78, a, consist of many angular por- 

 tions, cohering by elastic gluten; in the parallel An- 

 ther, rarely in the terminal one, the masses are rather 

 powdery, in plates, of easily separable granulations ; 

 in the terminal lid, fig. 78, a, they are usually waxy, 

 homogeneous and smooth : after the cells open, the 

 masses of Pollen, fig. 71, d, and fig. 72, stick by a ta- 

 per base, or elastic thread, to the Stigma, or any thing 

 else. Germen, fig. 78, d, roundish, obovate, or ob-
