GYNANDRIA. 353 



which I had, some time ago, communicated this 

 genus to the French botanists*, and which they 

 have adopted, becomes established. See Labillar- 

 diere's excellent work on New Holland plants, 

 where several species^of it are figured.

 Ayenia, Glut a, and Passiflora, Exot. Bot. t. 28, 

 most unquestionably have nothing to do with it, 

 their stamens being inserted below the germen, 

 merely on a columnar receptacle. The learned 

 Schreber therefore removed them to the fifth Class. 

 It has been thought that this Order might receive 

 a reinforcement from the Linnaean Pentandria 

 Digynia. Several of the Contorta have long been 

 suspected to belong to Gynandria; see Pergularia, 

 Ic. Pict. t. 16, and Andr. Repos. t. 184. In this 

 genus, as well as Cynanchum and Asclepias, the 

 pollen appears in five pair of glutinous masses, ex- 

 actly like the pollen of Orchidea, sticking upon the 

 stigma. Each mass of pollen is received into a bag, 

 or cell, formed by a valvular apparatus that encircles 

 the organs of impregnation, like the generality of 

 stamens. The pollen however is, in the above 



* I was not aware of Loureiro's Stylidium, a plant, according to his 

 description, of the seventh Class: FL Cochinck. v. 1. 221; but this 

 can scarcely interfere with ours, being probably, as it grows about Can- 

 ton, some well-known shrub that happened to have a seven-cleft flower. 

 It should seem to belong to the Rubiacea, notwithstanding some points 

 in the description.
