TRANSACTIONS OF WAGNER 
VEGETATION OF SOUTH FLORIDA 
168 
L. O. 20 Miles.—A low tree hammock was noted about 3 kilometers (2 
miles) to the east of the canal. 
L. О. 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. О. 23-L. O. 24 Miles. —De Soto Tiger, a noted Seminole, was killed 
here by a renegade white man on Dec. 28, 1g11. 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. O. 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. O. 31 Miles.—About half way, Nymphæa 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.
