the St. Mary’s River, South of Fort Wayne, Allen Co., IX. 16, 1906. 
In my own herbarium I may note the following collected 
by myself. 
No. 12, Notre Dame, 1907. Sterile. No. g10, Kizer, Dollar 
Lake, Ind., VI., 26, 1911. No. 691, Notre Dame, 1910. No. 376, 
Xs 10, *T900: 
This is P. coccinea var. asprella: No. 2242, Notre Dame, 1909. 
No. 8987, pond near Studebaker’s Woods, South Bend, Ind., 
VII. 12, 1911. The plant is sterile and corresponds to Var .asprella. 
No. 261, Notre Dame, IX., 16, ’09, var. asprella. No. 1809, 
Studebaker’s Woods, South Bend. IX., 16, 1911. This is the 
variety asprella. Some of the stems have the very narrow and 
small foliage characteristic of ordinary P. mesochora in its ter- 
restrial phases. No. 742. Sagunay, Ind., near Hudson Lake. IX, 
29, I9IO. 
No. 1618. Virginia, banks of the Potomac opposite Plummer’s 
Island, D. C. Specimen No. 1618x from the same rootstock as 
1618 is so much like the terrestrial of P. mesochora with its narrowed 
small leaves, that one could hardly tell them apart, and not 
knowing the origin of the plants, one would undoubtedly classify 
them as terrestrial phase of P. mesochora. 
These are properly P. coccinia var asprella. Other specimens 
of the variety asprella in its various phases are the following 
from Millers, Indiana and vicinity, collected at various times. 
The variation in numbers indicates either different dates of collection 
or different places.

Aguatic Puaske. The plant in the aquatic state resembles 
as to glabrous foliage perfectly that of the species. The plant 
never blooms in this phase, but scon emerges assurgently out of 
shallow water as the aérial leaves enlarge and one after another 
become nearly twice as long and broad. In June one may find 
such sterile aquatic phases with leaves 6-12 cm. long and 2-4
