DuRING THE SUMMER OF I9Q0!I 321 
Flelenium sp., and Rudbeckia Mohrit. 1 did not revisit the locality 
until August 22, at which time the /soetes seemed to have com- 
pletely disappeared, but a careful search revealed its dead and 
withered leaves lying flat on the moist ground, and the ripe spo- 
rangia buried just below the surface. 
| Number 1046, collected on July 11 around a cypress (Z7ax- 
odium inbricarium) pond near Cobb in the same county, had 
much the same appearance, though differing slightly in habitat. 
These two numbers last mentioned are referred by Mr. A. A. 
Eaton, who has examined some of my specimens, to /. flaccida 
rigida Engelm. (Trans. Acad. Sci. St. Louis, 4: 386. 1882), 
which he considers merely a later emersed state of /. flaccida. 
There are some discrepancies between my specimens and the 
original description of this variety, as regards season and _ habitat, 
but these may perhaps be due only to the difference in latitude, 
the original specimens having come from south Florida. 
The above observations on /soefes are mentioned chiefly to 
show the great necessity for further field work on the southern 
species, and to indicate that the genus may be found much more 
abundant in the Southern States than at present supposed. 
SAGITTARIA ISOETIFORMIS J. G. Smith, Rep. Mo. Bot. Gard. 6: 
£15, fF $3. 1095 
This interesting little plant was collected on the muddy margin 
of a small pine-barren pond in Decatur County, between Forest 
Falls and Bainbridge, August 12 (no. 1198), where it was accom- 
panied by Eleocharis tricostata, and it was seen a few hours later 
in and around Open Pond, in the same county. It seems to have 
been known hitherto only from peninsular Florida. 
The specific name is a most appropriate one, doubtless more 
so than its author realized. The submersed sterile form grows in 
great abundance in the shallow clear water of Open Pond near the 
shore, just as S. graminea does in New England, and it is here im- 
possible to distinguish it from /soetes without close examination. 
CYPERUS RETROFRACTUS (L.) Torr. 
While walking along the summit of the Pine Mountain range 
in Meriwether County, on the 29th of August, I noticed for the
