REMARKS. 



I. The Class IV. Tetrandria, being a numerous one, Linnaeus chose to separate it into two, and an opportunity presented itself from the 



consideration of the differences which occur in plants having four stamina, from the proportion of these. Didynamia expresses this 

 difference ; and the flowers are either ringent or personate, a natural tribe. But as all the ringent flowers are not included in the class 

 Didynamia, some coming under Class II. Diandria, there can be no good reason for not making this real division of a class into an 

 Order. The System hence becomes more easy and regular, and in fact frequently, more natural. 



II. The Class VI. Hexandria, also readily separates into two parts, from the like consideration of the proportion in the stamina, and Tetra- 



dynamia contains the natural tribe of cruciform plants. 



III. The Class XIII. Polyandria, also readily divides into two parts, from the consideration of the insertion of the stamina, and one of 

 these, the Icosandria, of Linnaeus, possesses many edible fruits, but as it is not altogether a natural class, therefore no one can regret 

 seeing this part distinguished as an order. 



IV. In the Monadelphia of Linnaeus, many of the numerical names, which had been used to characterize the Classes, are employed to dis- 

 tinguish the Orders, or subdivisions, as Pentandria, Decandria, &c. and hence arises a confusion unavoidably perplexing to the young 

 student, and which our Method, as is evident, completely removes. The same observation applies to the Classes Diadelphia, Polyadel- 

 phia, Gynandria, Monctcia, Dicecia, where the same (may I call it so) impropriety occurs. This class in Linnaeus is not natural, 

 but being made into orders, many of them then become natural as orders, as the Columnifer^e. 



V. The Papilionaceous Flowers, as they are generally termed, form the Order Decandria in the Class Diadelphia of Linnaeus; but the 



author, unwilling, as it would seem, to make any breach in so natural an assemblage of plants, has so far deviated from the principles of 

 his System, as to refer to that Class several genera, which strictly belong to the preceding Class, being in fact Monadelphious. This 

 inconvenience is entirely obviated in the present scheme, where Monadelphia and Diadelphia constitute two successive Orders in our 

 Class X. Decandria. 



VI. Polyadelphia is a small, and, as Doctor Smith observes, " rather an unnatural class." Most persons are shocked to see Citrus the 

 orange, in this class, and not in the Icosandria class; for Linnaeus describes it of the Class XVIII. Polyadelphia, Order III. Icos- 

 andria. Now in our Reformed Sexual System, it comes under Class XIII. Polyandria, Order Icosandria, in juxta-position with 

 other edible fruits, in the subdivision Polyadelphia. 



VII. Class V. Pentandria, a very numerous class, is subdivided by Syngenesia, and so formed into two classes by Linnaeus, the latter 

 of which, however, as containing an order Monogamia, is not therefore altogether a natural class. We obviate this by making Syn- 

 genesia an order, and the subdivision Polygamia to contain the natural tribe of compound flowers; whilst, under another subdivision, 

 Monogamia, many plants, not having compound flowers, arrange themfelves. 



VIII. Against Gynandria, which Doctor Smith calls, "an odd and miscellaneous class," there lies the same objection, as we observed 

 above, as against the Class Diadelphia, the numerical names of Classes being applied to Orders. In our scheme, Class II. Diandria, 

 has an Order Gynandria, which contains the natural tribe of Orchises; and thus the mind is delighted to see a natural assemblage 

 embraced in an order, if not in a class. The separation of the remainder cannot be regretted, as not possessing amongst each other the 

 smallest affinity. 



IX. Monolcia is a miscellaneous class, and borrows the names of its secondary divisions from most of the other classes, as Monandria, Di- 

 andria, &c. nay even from Monadelphia, Syngenesia, and Gynandria ; for all these become, in Linn^eus's Sexual System, Orders. 

 In our scheme, Class Triandria, Order Monacia, contains mostly grasses, hence we retain this natural assemblage in the same class 

 at least, if not in the same order. 



X. Diozcia. The same remarks apply here, as in Monozcia. 



XL Polygamia subdivides the classes Monxtia and Dicecia ; therefore in the logic of science it is in reality an order.
