90. Melastoma are not distinguished by Linnaeus from 

 his Calycanthemec. 



91. Salicaria are in the same predicament. Jussieu 

 has considerably the advantage here. 



92. Rosacea embrace the Seuticosrc, ord. 35, and Po- 

 macea, ord. 36, of Linnaeus, nor can there be a more na- 

 tural assemblage. 



93. Leguminosce comprehend, in like manner, two 

 Linnaean orders, Papilionacea, the 32nd, and Lomentacea, 

 the 33rd, which we should be disposed to keep distinct, 

 however nearly they must be considered as akin. The 

 Linnaean characters, though often termed artificial, serve 

 Jussieu for the distinctions of his sections. 



94. Terebintacece, on order learnedly sketched out, ra- 

 ther than completed, by Jussieu, which seems entirely to 

 have escaped the perception of Linnaeus. It brings to- 

 gether many things which he either did not pretend to ar- 

 range, or which clogged some of his orders. 



95. Rhamni constitute a very natural order, of which 

 the Linnaean Dumoscc, ord. 43, are but a sketch, confess- 

 edly imperfect. 



Class 15. 



96. Euphorbia are Linnaean Tricocca, ord. 38. 



97. Cucurbilacece agree, in name as well as idea, with 

 the 34th of the Linnaean orders. 



98. Urticcc are nearly analogous to Scabrida, ord. 53, 

 except that Piper is mentioned as related to them, instead 

 of being referred to a monocotyledonous order with Arum, 

 Pothos, Acorus, 8cc. Yet its germination is rather hinted 

 at than determined, nor does any thing positive seem to be 

 known on that subject. 



99. Amentacece are mostly what Linnaeus has, under 

 the same appellation, in his 50th order. 



100. Conifera are his 51st, bearing the same name. 



As Linnaeus enumerates, at the end of his Natural 

 Orders, J 16 genera, which he could not then satisfac-
