A LIST OF PLANTS COLLECTED IN LEE COUNTY, 



FLORIDA. 



BY A. S. HITCHCOCK. 



The plants included in the following list were collected 

 at several points in Lee county, Florida, in July and August, 

 1900. My headquarters were at Myers, on the Caloosa- 

 hatchee river, at which place most of the numbers were 

 collected. Collections were made also at Alva, about 

 twenty-five miles up the river, at PuntaRassa and Sanibel, 

 at the mouth of the river, and at Marco, an island a con- 

 siderable distance down the coast. A few plants were col- 

 lected at Everglade, at the southwest corner of the county. 

 Of all the plants in proper condition and in sufficient abun- 

 dance, ten sets were prepared. Full sets contain 500 forms, 

 though the total numbers are 549. Several species were 

 obtained which are not represented in the sets. 



In the vicinity of Myers the most extensive formation is 

 the flatwoods. This is fiat, sandy land covered with forest 

 of the long-leaved pine. Beneath is the saw palmetto with 

 other low shrubs, such as scrub oak and Andromeda fruti- 

 cosa. In the flatwoods are ponds which contain water the 

 year around. Various water plants grow here and there is 

 usually a growth of button bush {CephalantJuis) in the cen- 

 tral part. Other depressions contain cypress trees and are 

 called cypress swamps. Besides these there are shallow 

 depressions which contain water only during the rainy sea- 

 sons and which I have called wet-weather ponds. Such 

 depressions are characterized by the absence of the pines 

 and saw palmetto and the presence of certain herbs, which, 

 in most cases, are also found around the ponds. Around 

 the permanent ponds there is usually a broad open space
