30 Addisonia 



Our native heliotropes are nowhere as conspicuous as in southern 

 Florida. The margins of the Everglades and the adjacent prairies, 

 as well as the flatwoods northward, commonly support large areas 

 covered with a growth of heliotropes. 



This species is the heliotrope of the Everglades and the connecting 

 prairies and adjacent low pinelands. It also, apparently, occurs at 

 outlying localities. The original specimens were collected by Dr. 

 M. C. Leavenworth, evidently during the Seminole w^ars, and are 

 recorded as coming from Tampa Bay. We have specimens col- 

 lected during the same period nearer the natural center of this 

 plant's geographic distribution. The label reads "Found in 

 Alpatiokee Swamp (pine woods) near Fort Vinton, Fla." A note 

 accompanying the label in Dr. Torrey's handwriting says, "Sent 

 to me by U. S. A. ofificer whose name I have unfortunately lost. 

 J. T." This swamp, now called Halpatiokee, was recently traversed 

 by the writer, w'ho can testify that the plant still grows there in 

 great abundance. 



On the edges of the everglades and in the adjacent low pinelands 

 this plant often grows very abundantly, forming carpets of yellow 

 as far as the eye can see. 



After the early collections cited above the plant was collected 

 only a few times in the latter half of the last century. It was only 

 after the botanical exploration of Florida was taken up by the 

 Garden and the writer that its geographic range became evident. 



The specimens from which the accompanying illustration was 

 made were collected by the w-riter May 20, 1918, from plants 

 transplanted from the Everglades, and grown in the reservation 

 of Mr. Charles Deering at Buena Vista, Florida.
