natural Family of Plants called Composita: 101 



at variance with the foregoing observations, that although in an 

 assemblage of flowers priority of expansion generally indicates a 

 greater degree of perfection, and consequently a more ready con- 

 vertibility of the hermaphrodite into the female flower; yet in a 

 hermaphrodite flower the development of stamina usually pre- 

 cedes that of pistilla. The most remarkable exceptions to this 

 order of development which I at present remember, occur in 

 several species of Plantago, where the stigmata are fully deve- 

 loped, and often even withered, before the bursting of the antherae. 



I now proceed to make some remarks on certain genera of 

 Compositae which either occur under different names in late syste- 

 matic works, or whose structure and limits seem to be imper- 

 fectly understood. 



SoLIVA 



was estabHshed in the Prodromus Florae Peruvianas et Chilensis,- 

 and is adopted by Persoon in his Synopsis Plantarum. 



To this genus Hippia minuta of the Linnean Herbarium un- 

 questionably belongs, and it is perhaps not specifically distinct 

 iVoni SoUva pedicellata. But on comparing the structure of this 

 plant with the figures and descriptions, given by Mons. de Jus- 

 sieu (in the fourth volume of the Annales du Museum,) of the dif- 

 ferent species of his Gymnostyks, it appears to me evident that the 

 whole of this genus is referable to Soliva, whose principal charac- 

 ters would consist in the want of corolla or perhaps its accretion 

 with the persistent style in the female florets ; in the pericarpia 

 being more or less winged, and presenting their disk instead of 

 their margins to the centre of the capitulum.
