VEGETATION OF SOUTH FLORIDA 



L. O. 20 Miles. A low tree hammock was noted about 3 kilometers (2 

 miles) to the east of the canal. 



L. 0. 21 Miles. The launch passed unbroken saw-grass, sweeping to the 

 distant horizon. The embankments have been so recently formed that there 

 has not been time for the establishment of weeds. The edge of the canal is 

 fringed with saw-grass, Sagittaria lancifolia L., Piaropus crassipes (Mart.) 

 Britton, and Pontederia cordata L. 



L. O. 23 Miles. The white water-lily, Castalia odorata (Dryand.) Woodr. 

 & Wood, was noted in the canal. 



L. O. 23~L. 0. 24 Miles. De Soto Tiger, a noted Seminole, was killed 

 here by a renegade white man on Dec. 28, 1911. Natural vegetation grows 

 on both banks of the canal. Large white-crane was noted where we trans- 

 ferred to the launch Frances. A large blue-heron was seen. 



L. O. 26 Miles. Here the saw-grass vegetation is dominant without 

 hammocks and with the water in the canal and on the glade land at the same 

 level. 



L. 0. 27 Miles. The saw-grass forms the exclusive growth with no ham- 

 mocks. A large slue, or channel, was filled with the white water-lily, Castalia 

 odorata Woodr. & Wood, also Crinum americanum L., Pontederia cordata L. 

 and Sagittaria lancifolia L. Here the native plants are not admixed with any 

 introduced weeds, which are absent. 



L. O. 28 Miles. The portion of the Glades north of this point may be 

 termed Upper Glades, because the vast saw-grass marsh is unbroken either 

 by hammocks or channels. Before the canals were cut the Indians never 

 penetrated the Upper Glades on account of the absence of open water and the 

 density of the saw-grass. A small willow hammock was passed to the right, 

 close to the canal. The low trees were loaded with epiphytes. 



L. O. 29 Miles. The channels become more frequent and they are filled 

 in part with water-lilies, spider-lilies, pickerel-weed and other aquatic plants, 

 as also the lagoons surrounded by unbroken saw-grass. 



L. O. 30 Miles. The saw-grass is everywhere. 



L. 0. 31 Miles. About half way, Nymphaea advena macrophylla 

 (Small) Miller & Standley, the spatterdock, was seen in a slue here. A tree 

 hammock was seen about one-half mile away from the canal with a channel 

 leading toward it. The banks were covered with loose limestone rock brought 

 up from the bottom of the canal by the suction dredge.
