328 POLYANDRIA. 



are very doubtful. Caryocar, whose large rugged 

 woody nuts contain the most exquisite kernel ever 

 brought to our tables, and which is the same plant 

 with Geertner's and Schreber's Rhizobolus, as the 

 excellent Willdenow rightly judged, is not certain 

 in number ; and still less the Cimicifuga ; whilst 

 JVahlbomiais probably a Tetracera : see Willdenow. 



5. Pentagynia contains chiefly Aquilegia the Colum- 

 bine, and Nigella both strictly allied to genera in 

 the third order. Reaumur ia indeed is here well 

 placed. Some Nigellce have ten styles. 



6. Hexagynla consists of Stratiotes, Engl. Bot. t.379', 

 and Brasenia, a new genus of Schreber's with which 

 I am not acquainted. 



I would recommend an union of the last five 

 orders, for the same reason that influenced me in 

 the preceding class. They now only serve to keep 

 natural genera asunder, the species of which not 

 only differ among themselves as to number of pistils, 

 but each species is often variable besides. The genera 

 are so few that no inconvenience could arise on that 

 account. I conceive such reforms, founded in expe- 

 rience not in theory, serve to strengthen the system, 

 by greatly facilitating its application to practice. 



7. Polygynia. An order for the most part natural, 

 comprehending some fine exotic trees, as Dillenia, 

 Exot. Bot. t. 2, 3, 92 and 93 ; Liriodendron, the 

 Tulip-tree ; the noble Magnolia, &c. ; a tribe con-
