in our time, used to amuse themselves with the idea, that 

 the Professor would not allow this fine plant a place in 

 the garden, because he knew not where to class it in his 

 system. 



82. Caryophylles are exactly analogous, except a few 

 rather doubtful genera at the end, to the similarly named 

 22nd order of Linnaeus. But between this very natural 

 tribe and the last, Rut aces, there is a hiatus valde dejlen- 

 dus, as to any natural affinity ; the present order being- 

 much more related, as Jussieu candidly indicates, to the 

 Amaranthi, ord. 30, and proving that the presence or ab- 

 sence of a corolla, is no more infallible than any other 

 character, for a general principle of arrangement. 

 Class 14. 



83. Sempervivs are the second section of Linnaeus 's 

 Succulents, ord. 13. 



84. Saxifrags are chiefly the fourth section of the 

 same. 



85. Cacti consist merely of Ribes and Cactus, as arti- 

 ficial a combination as most in the sexual system itself. 

 The former Linnaeus ranks with his Pomaces, ord. 36 ; the 

 latter is the first genus of his Succulents. 



86. Portulaces are selected out of the first and third 

 sections of the Succulents. 



87. Ficoides consist of more of the same. 



In this part of their respective systems, we find it more 

 difficult than usual to follow the ideas of the learned au- 

 thors. Habit seems to have guided Linnaeus ; but Jussieu 

 tracing, in his last five orders, nearly the same affinities, 

 has somewhat strained his technical characters to confirm 

 them. 



88. Onagrs accord, in the main, with the Linnaean 

 Calycanthems, ord. 17. They well connect the five pre- 

 ceding orders with the following. Bsckea belongs to the 

 Myrti. 



89. Myrti are the Linnaean Hesperides, a very natural 

 family, much amplified by Jussieu from recent discoveries.
