1g0 BOTANICAL GAZETTE [SEPTEMBER 
belonging to one of the original specimens from this station 
reads: ‘‘Muddy and gravelly shores of Nanticoke River near 
Seaford, Delaware. Wm. M. Canby, Wilmington, Del., August 
1874.” That this was the first collection at this station is shown 
by the fact that duplicates in the U. S. National Herbarium and 
in the Herbarium of the Field Columbian Museum bear the state- 
ment that it is ‘‘a new station.” The area occupied by Isoetes 
at this place is located ‘‘nearly opposite the town, a little above 
it, in fact. The space there is not very large, perhaps 100°” ° 
(30™). 
3. Back Creek, tributary to Elk River, eastern shore of Mary- 
land. This station is on the south shore of the creek about 3*™ 
from the western end of Chesapeake and Delaware Canal and 
nearly 1*" below Chesapeake City. The first collection was 
made by T. C. Palmer in August 1893. He made further col- 
lections the following year and published a short statement in 
the BoTANICAL GAZETTE.’ 
oe Piney Creek Cove is a broad indentation in the north shore 
of Elk River 9-11*™ from its mouth. On August 13, 1894, 
T. C. Palmer collected Jsoetes saccharata, just below the mouth of 
the small stream which empties at the northeast angle of the 
cove. This station was also mentioned with the last in the 
BoranicaL GAZETTE. 
5. Town Point is the upper angle formed by the confluence of 
Bohemia River with Elk River, into which it flows from the east. 
About 500™ north of this point Isoetes was collected on July 31, 
1896, by T. C. Palmer. A specimen from this collection in the 
National Herbarium gives the habitat: ‘Tidal tract; gravel 
nearly bare.” This station has not been previously recorded. 
6. Cabin Johns Creek empties into Elk River from the south- 
east about 5*™ above the mouth of the latter. A specimen in 
the National Herbarium bears the data: ‘July 21,1896. Cabin 
John’s Creek, Elk River. Tidal tract; gravel covered with mud. 
Collector T. Chalkley Palmer.’’ This collection has not been 
published heretofore. 
7. Lloyds Creek is a large shallow cove on the south shore of 
*William M. Canby, in a letter. 7 Bort. GAZ. 20: 32. 1895.
