Justice Joseph E. Adderley, at Bight ilile Rocks, Great Bahama, Informed us 

 at the time of our visit there in February, 1905, that soon after the hurricane of 

 August 13. 1899, this sedge appeared in clearings, and had soon spread as a trouble- 

 some weed through cultivated lands, killing out pasture grasses in places ; it had 

 therefore come to be called there " Hurricane Grass."
