400SYNGENESIA— POLYGAM.-^QU.Eupatorium. 



y. In dry places where water has been, or about the margins of 

 ponds. 



Annual. September. 



Root with many stout fibres. Herb more erect, and taller, with less 

 extended branches than the foregoing species. Leaves undivided, 

 pointed, less deeply serrated ; the upper ones dilated at the 

 base and often combined, embracing the stem. FL drooping, 

 though their stalks are quite straight to the very summit, larger 

 and handsomer than the last, especially when furnished with 

 their spreading golden rays in the variety |3. The seeds are often 

 smooth, and their bristles, always rough, are 4. 



y is certainly nothing more than a starved plant of this species, 

 growing out of the water. The Jiuwe)- is drooping in my speci- 

 men from Miller's herbarium, though drawn erect by Dillenius. 

 I have an analogous small variety of B. tripartita from Switzer- 

 land.
