I possess this plant from almost all the warm parts of 

 South America, from the Cape of Good Hope, from the 

 Mauritius, and from New Holland. The flowers are so 

 crowded as to make the spike appear almost cylindrical. 

 The calyx is closed over the fruit, splitting down to the base 

 in one or more places, most readily on each side of the 

 shorter tooth, which often thus constitutes a separate leaflet. 

 The Verbena littoralis of Humboldt seems to be a variety of 

 this with shorter spikes than usual.

 tetrairono, foliis lanceolatis acutis sessilibus subconnatis 

 venosis grosse serratis, spicis breviusculis, corolla calycem 

 cylindraceum plusquam duplo superante. 



Hab. In Provincia Bonaria^, et in Pampas non raro occurrit. 



Ubique tactu asperrima. Folia rigida, laete atque pallide 

 virens. SpiccB paucae, ternatas nunc proliferae, unciam et

In general aspect the present species approaches the fol- 

 lowing rather than the preceding. The bracteae are like 

 those of V. bonariensis, but the flowers are very different, far 

 more showy, and of a blucish purple colour. Calyx splitting, 

 when the inclosed fruit is ripe, as in the foregoing.
