 The plant seems to havebeen overlooked by Linnœus, and is not noticed 

 by hini, although other plants first inentioned by Paolo Boccone were 

 not passed over in the Synonyms cited. 



Poiret thus distinguished the plant in his earlier work (1789) : — 

 « Cette espèce pousse des tiges nombreuses, longues, un peu velues. 

 « Les feuilles sont linéaires, un peu aiguës, glabres ; les fleurs sont dis- 

 « posées en panicule. La corolle est blanche ; les pétales sont cachés par 

 « le calice qui est plus long. Les divisions du calice sont hérissées de 

 « poils dans leur milieu, lisses et membraneuses à leurs bords. » Poiret
