columnar receptacle. The learned Schreber 

 therefore removed them to the 5th Class. . 



But this Order may receive a reinforce- 

 ment from the Linnanin Pentandria Digy- 

 7iia. Several of the ContortcE have long- 

 been thought to belong to G;/7fr7/?r//7<7; see 

 Fergularia, Ic. Pict. t. 10", and yindr. 

 Repos. t. 184. In this genus, as well as 

 Cynanchum and Asclepias, the pollen is 

 borne in 5 pair of glutinous masses, ex- 

 actly like the pollen of Orc/ndece, by 5 

 glands upon the stigma. Some obscurity 

 arises from each mass of pollen being re- 

 ceived into a bag or cell, formed by a pe- 

 culiar valvular apparatus that encircles the 

 organs of impregnation, and bears a great 

 resemblance to stamens. The pollen how- 

 ever is, in the above genera, not attached 

 to these cells or valves, but to the 5 

 glands, each of which is double, and all of 

 them seated on that thick abrupt angular 

 body which acts as a stigma*. Nor is 



* Mr. R. Brown believes the cells s-ecrete the pollen, 

 and project it on the stigma, as the pollen of some 

 Orchidecc sticks to any part of the plant. If so, these 

 plants must remain in Peniandria.
