genera of this order, are, with Cistus, subjoined to the 

 Linnaean Rotacea, ord. 20 ; certainly with no very evi- 

 dent reason. 



69. Guttiferce constitute a well-marked order, to which 

 Linnaeus has nothing analogous. Most of the genera that 

 compose it, are either left by him unarranged, or con- 

 sidered as of dubious affinity to any others. Indeed they 

 are generally tropical trees, respecting which he had but 

 slight information. 



70. Aurantia. Of this likewise Linnaeus seems to 

 have formed no idea, since he refers Citrus to his Bicornes, 

 and leaves Limonia undetermined. Camellia and Thea, 

 subjoined by Jussieu, with some other genera, to this 

 order, as connecting it with the next, appear to us of very 

 dubious affinity to the Aurantia ; nor are they much bet- 

 ter annexed by Linnaeus to his ColumnifercB, ord. 37. 



71. Melia constitute a good order, comprehended, not 

 very judiciously, under the Linnaean Trihilata, ord. 23, 

 above mentioned. 



72. Vites, consisting only of Cissus and Vitis, we have 

 already mentioned, ord. 59, as included amongst the He- 

 deracece, ord. 46, of Linnaeus. 



73. Gerania make a part of the Linnaean Gruinales, 

 ord. 14, but Tropaolum, a puzzling genus, which Jussieu 

 labours to prove in many respects related to them, is re- 

 ferred by Linnaeus, as reasonably perhaps, to his Trihi- 

 latcc. 



74. Malvacea are almost exactly analogous to the Co- 

 lumniferee, ord. 37. 



75. Magnolia, form an order certainly as little con- 

 nected with the preceding as any two could be in the most 

 artificial system. See the following. 



76. AnoncB. The leading genera of this and the Mag- 

 nolia compose the Limraean Coadunatte, ord. 52. 



77. Menisperma are referred by Linnaeus to his Sar- 

 meutacea, ord. 11, by their habit more than any just 

 character.
