200 COMPARISON OF THE NATURAL ORDERS 



ence in the Cotyledons of one genus, might well justify 

 him in not dividing an Order on that account, and 

 possibly cherished this idea, as an irrefragable proof 

 of his position, that no character whatever was free 

 from exception in natural orders. Neither the de- 

 duction, nor the fact as to Nymphtea, is now -ad- 

 mitted, and yet the Lentibularia of Brown, see (Ord. 

 34) p. 96, and Cuscuta, see Convolvuli, are strong ex- 

 ceptions. 



12. HOLERACEJE- A large Order, of which the 

 1st section is composed of many of Jussieu's Atri- 

 plices 29 ; the 2d of more of the same, with Calligo- 

 num, one of his Polygonece 28 ; the 3d of Axyris 

 only, one of his Atriplices ; the 4th of some Ama- 

 ranthi 30, and some Atriplices ; the 5th of Poly- 

 goneie 28, with Begonia their ally in habit, see a re- 

 mark on Jussieu's 52d Order; the 6th ofNyssa, Mi- 

 musops, Rhizophora and Bucida ; the 7th of Anacar- 

 clium (removed by a manuscript note from the 6th 

 section), Laurus, Tinus, Wintcrania and Heist eria. 

 There is no analogy between these two latter sections 

 and any of Jussieu's Orders. His Lauri 27, a good 

 Order, was not perceived by LinnaBus. 



13. SUCCULENTS Cactus., one of Jussieu's 85th 

 Order, with some of his Portulac&E 86, and Ficoi- 

 dea 87, make the 1st section; Sempewvc* 83 are 

 the 2d ; some more Portulace<z chiefly compose the 

 3d ; and S&pifragee 84 are the 4th section of this 

 Order, iu which Linuaeus was guided by habit, and
