 Further distrib. cosraop. None of the earlier explorers in the Galapagos 

 Ids. mention this weed of cultivated ground. It was first noted in the 

 group by Andersson on Charles Isl. in 1852, and its present much more 

 general distribution among the islands well shows the fact that inter- 

 communication between them must now be such as to carry seeds 

 frequently from one to the other.
