CHAP. XXXII. 



OF THE GENERA REJECTED BY THE SYSTEM, AS 



GROUNDED ON THE VARIATIONS OF SOME 



PARTS ONLY OF THE FRUCTIFICATION. 



IT has been observed in Chap. 2.9th that there 

 are few genera, wherein all the parts of fructifica- 

 tion are constant in every species ; and that this 

 inconstancy of particular parts had been another 

 source of error in former Botanists : We shall here 

 give a list of these mistakes, referring the old genera 

 to the new titles, in the same manner as we did those 

 in the list given in the preceding chapter. 



OLD GENERA. NEW GENERA. 



Arisarum Arum, with a hooded spatha. 



Asteriscus Buphthalmum, with a starry leafy calyx. 



Silybum Carduus, with a thorny calyx. 



M Id ' C Dracocephalum, with the calyx gibbous 



{. and bilabiate. 



/Tithymaloides jf Eu P horbia > with the calyx gibbous and ir- 



* C. regular. 



Trionum Hibiscus, with an inflated calyx. 



p- . C Ranunculus, with a triphyllous calyx and

Jva Teucrium, with a gibbous calyx. 



Lunularia C Marchantia, with the common calyx 



ifc quadrifid. 



Leuc an themuml Chr ^ anthemum ' with the s< l uamae of the

Cardiaca Leonurus*, with a quinquedentate calyx. 



p , . f Herniaria, with the leaves of the calyx 



* The scarlet Leonurus of the Cape is removed to the ge- 

 nus Phlomis, oji account of its wanting the shining 1 points on 

 the antherae; but the title Leonurus is nevertheless applied tt> 

 the Cardiaca.
