dria. Its fruit is a membranous winged 

 capsule, opening at the top. Monsonia, 

 Curt. Mag. t. 73, Lamarck, U 638, re- 

 moved by Schreber and Willdenow to 

 Monadelpliia, rather, I think, belongs to 

 this class where Linnaeus placed it. The 

 5 filaments, bearing each 3 long-stalked 

 anthers, are merely inserted into a short 

 membranous cup, or nectary, for so the 

 analogy of the 3 preceding genera induces 

 us to call it; and if we refer Monsonia to 

 Monadelphia, we fall into the error of Ca- 

 vanilles mentioned p. 439- Lastly, Citrus, 

 the Orange, Lemon, &c, Lamarck, t. 639, 

 most unquestionably belongs to this Order. 

 Its stamens are about 19 or 20, combined 

 variously and unequally in several distinct 

 parcels ; but those parcels are inserted into 

 a proper receptacle, by no means into the 

 calyx, as the character of the Class Icosaii- 

 dria indispensably requires. Even the 

 number of the anthers of Citrus accords 

 better with most plants in Dodecandria 

 than in Icosandria, notwithstanding the 

 title of the latter.
