RHYNCHOSPORA FUSCA (L.) Ait. f. 
Collected on the sandy margin of a pine-barren pond in the 
northern part of Lee County (as just mentioned) July 13 (no. 
1067). This species has apparently been reported but on 
before from the Southern States. Mr. M. L. Fernald * mentions 
its having been collected by A. H. Curtiss, at Milton, Santa Rosa 
County, Florida (no. 5929, July 8, 1897). The specimen under 
this number in the U. S. National Herbarium looks very much 
like mine, but the one at the New York Botanical Garden has a 
somewhat different appearance and may not represent the same 
species. I have more recently discovered that Mr. Nash's no. 
1321, from the sandy shore of Lake Juana, Lake Co., Florida, 
July, 1894, distributed as R. gracilenta, is also R. fusca, at least 
the representation of it in the U. S. National and Columbia Uni- 
versity herbaria; and Mr. Fernald informs me that the material 
in the Gray Herbarium is the same. These southern specimens 
differ from northern and European ones in being a little more 
slender, but otherwise seem to be identical. 
RHYNCHOSPORA DODECANDRA Baldw. 
Collected on the rosemary sand-hills of Emanuel County, 
where it is one of the most characteristic species, June 28 (no. 
977); also in very dry white sand about two miles from Open 
Pond, Decatur County, August 13 (no. 1216), where it was as- 
sociated with Paronychia riparia, Dicerandra linearifolia, Serenoa 
and Stipulicida. It does not seem to have been reported from 
Georgia before, or so far inland, these two stations being about 
sixty miles from the coast. 
Mayaca FLUVIATILIs Aubl, 
Mr. Fernald has recently reported + the collection of this 
South American species by Mr. Curtiss last year in Florida. It 
is represented in my 1901 collection by no. 1179, from a cypress 
pond in Thomas County, August 9. There are some differences 
between this species and MM. Audleti which Mr. Fernald failed to 
mention. The leaves of M: fluviatilis are much longer and more
