Fence rows and low shaded grounds : throughout the United States. J"!. July. Fr, 

 August - September. 



Obs. This plant is frequently to be seen in low grounds, along streams, 

 and sometimes along fence-rows and borders of fields ; but it has not be- 

 come generally known as an intrusive weed. An observing farmer, how- 

 ever, has recently brought to me some specimens of it collected in his 

 fields, — where, he assured me, he found it a very troublesome weed — and 

 moreover, exceedingly difficult to extirpate. I have, therefore, deemed 

 it proper to describe the plant, and commend it to further notice, — so 

 that its true character may be certainly determined, before its inroads 

 become extensive. Since the above remark was written (1846), the plant 

 has become very troublesome on some farms in Pennsylvania.

 fruit become httle nuts or hard akenes, each with a single seed without albumen. Herbage 

 not aromatic.

 A few are slightly medicinal. The Alkanet of commerce (a red coloring matter) is afford- 

 ed by a plant of this Order, viz. ; Anchusa tinctoria, L. Several species have showy 

 flowers, and some of the Heliotropiums are admired for their fragrance.
