Farther distrib. cosmop. None of the earlier explorers in the Galapagos 
Tds. mention this weed of cultivated ground. It was first noted in the 
8toup 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.
