1903] Bissell,— Station for Dentaria maxima - 169 
to the display. When visiting this spot last year in the first days of 
May I collected some plants that at first I thought were only a 
peculiar form of D. diphylla. A more careful examination of the 
specimens, however, showed a decided difference in the rootstock. 
Another visit was then made to the station, more material collected 
and observations made. 
Specimens of this peculiar form were later sent to the Gray Her- 
barium and found by Dr. Robinson to be the rare Dentaria maxima, 
Nutt. Hartford County, Connecticut can now be added to the 
recorded stations for this species in New England. As the plant is 
little known some notes may be of interest. 
'There were found two colonies of about a dozen plants each sur- 
rounded by plants of both the other species. "There has been some 
discussion as to the time of flowering of D. maxima. At this station 
D. laciniata bloomed a week or ten days earlier than D. diphylla. 
D. maxima was almost exactly intermediate in time between the other 
two. It is supposed to be a larger plant hee the others but was 
about the same size in this case. 
The: basal leaves were like those of the stem. There were usually 
three leaves on a stem, sometimes two and occasionally four, when 
three the upper one was smaller, when four, the last one was very 
much smaller than the others. 
The flowers were nearly white, just tinged with rose or purple 
much like those of D. /aciniata. None of the plants matured fruit, 
in this respect following D. diphylla which seems hardly ever to form 
seed in this section. 
The rootstock is larger and longer than that of D. /aciniata, it is 
jointed and tubercled, grows deeper in the ground and is not at all 
like that of D. diphylla. 
SOUTHINGTON, CONNECTICUT. 
SINCE above was in type has come a report of the finding of 
Dentaria heterophylla, Nutt. in Litchfield County, Connecticut, thus 
making four known species of Dentaria in New England instead of 
three as stated above.—C. H. B. 
SPLACHNUM AMPULLACEUM, A CoRRECTION.— The moss reported 
from Mt. Ktaadn as .SP/achnum roseum (RHODORA 5: 44) has proved 
on further study to be S. ampullaceum and I wish to place on record 
this correction.— LeRoy H. Harvey, University of Chicago.
