Linnaeus employed the generic name in the first edition of 

 his Systema, (1835), but that is a mere Hst of genera. 



POMBALIA, VandelH Fasc. PI. 7 (1771). 



This long antedates lonidium as a generic name, for the latter 

 was not published until 1803 (Vent. Hort. Malm. 27, t. 27). 



l^ombalia is based on the South American plant commonly 

 known as lonidiuui IpccacnanhcE which Vandelli described as 

 Poinbalia IpccacuanJicB, giving a very good figure of it. There 

 seems no good reason, then, for not using the older name. 

 As to related genera, Solea, Spreng, as also older than lonidium, 

 dating from 1800, and was thought by Dr. Gray to be distinct, 

 although united with lonidium by Bentham and Hooker. Hy- 

 bantJius, Jacq. Enum. Carib. 2 (1760) is the oldest named of the 

 group, based upon the spiny plants of the West Indies, and 

 Baillon unites them all under this name. But if we follow Dr. 

 Gray in keeping up Hybant/ius, (Bot. Gaz. xi. 293), then the 

 next oldest name is Pombalia. 



Silene Caroliniana, Walt. Fl. Car. 142 (1788). 



Silene Pennsylvanica, Michx. Fl. Bor. Am. i. 272 (1803). 

 There is a specinen of this plant in Walter's Herbarium, 

 marked " Silene an Virginica," evidently a type of his description, 

 which fits it exactly. In the Linnaean Herbarium there is also a 

 specimen of it marked Virginica, by Linnaeus, but pinned fast 

 to the sheet is another bearing a good specimen marked only 

 '• K," indicating that it was received from Kalm, of the 5. Vir- 

 ginica of the description in Species Plantarum, 419. Linnaeus 

 evidently did not distinguish the two species.
