320 Harper: BoTaNnicAL ExpLORATIONS IN GEORGIA 
ADIANTUM HISPIDULUM Sw. Syn. Fil. 124. 1806 
Collected in an apparently unused well in the outskirts of 
Thomasville, where it was accompanied by Woodwardia areolata, 
on the morning of August 9 (no. 1171). As far as I know, this 
Old World species has never been reported as growing spon- 
taneously in the United States. It was fairly abundant and fruit- 
ing copiously, and seemed as much at home as the Woodwardia, 
which is a common inhabitant of wells in South Georgia.* 
IsOETES FLACCIDA Shuttl. 
This species (or some forms of it) is represented in my 1901 
collection by five numbers, all from the coastal plain, though no 
species of /svetes had previously been reported from the coastal 
plain of the southeastern United States outside of Florida. 
Numbers 843 and 951, partly emersed, were collected in 
June in a sluggish pine-barren stream in Bulloch County, and no. 
1112 was found in a similar situation in Sumter County, July 24. 
It is not absolutely certain that these three numbers represent the 
typical /. flaccida, which grows in “lakes and clear streams, middle 
and west Florida,” and is said + to mature in April and May and 
disappear in June. 
Number Io!o is a plant of rather different habit and habitat. 
It was found in wet pine-barrens around a mayhaw (Crataegus 
aestivalis) pond in Sumter County, and was a smaller and stiffer 
plant than the others. It grows in the greatest abundance, but so 
concealed by the tall grass that one might walk over it day after 
day without suspecting its presence. I only discovered it acci- 
dentally by pulling up a specimen with another plant, but on 
getting down on my knees I found it in apparently inexhaustible 
quantities. At that time, July 5, there was more water in these 
pine-barrens than I ever saw before or after, and yet none of the 
Asoetes was completely submersed, so it is almost a strictly ter- 
jenn SS kee species accompanying it were Sag vb 
u stata, Khynchospora Tracyi, Rhexia arts- 
tosa, Sabbatia campanulata, Breweria aquatica, Gerardia linifolia, 
i On a subsequent visit (Sept. 18, 1902) the Adiantum was found to be still flour
