3. Pentandria. Xanthium, Ambrosia, Ne- 

 phelium, Parthenium, Jva and Clibadium 

 all partake, more or less accurately, of the 

 nature of compound flowers, but their an-^

 referred to the Class Syngenesia ; particu- 

 larly Xanthium and Nepkelium, whose 

 fertile flowers have 110 resemblance to that 

 Class. Amaranthus, an extensive duno*-*

 our Chenopodium, follows next. Leea is 

 the same with Aquilicia, and belongs to 

 Pentandria Monogynia, the former name 

 being retained for the sake of the highly 

 meritorious botanist and cultivator whom 

 it commemorates. The Gourd tribe, Cu* 

 curbita, Cucumis, Bryonia, Engl. Bot. 

 f. 439, might be brought hither from the 

 abolished Order Syngenesia, unless it 

 should be thought better to consider them, 

 as polyadelphous, to which I am most in- 

 clined.
