Is Botrychum dissectum a Sterile 
Mutant? 
In answer to this query, first put by Prof. Chamber- 
lain in the Botanical Gazette, and passed on by- the 
JOURNAL to its readers, the following have been received. 
In regard to Botrychium dissectum, I wish to call your 
attention to a find I made this September in Cass Co., 
Indiana, in a sandy black-white oak wood. I found a 
field of about three acres that had been cleared in the 
center of a large wood. This wood was until recently 
an Indian reservation. The cleared field was an old 
camping ground with a spring near the center. About 
the low place were elevated places which you might 
call hills, say about fifteen to twenty feet in height. 
The soil is very sandy. On the south side of the cleared 
field or opening and within fifty feet of the woods on 
the south side of the field and somewhat in the shade 
of a few small trees that have grown up, I found a 
single B. obliquum. I searched for more but could not 
find any. But there were literally hundreds of B. 
dissectum of all sizes. The associates were Lechea 
villosa, Lechea sp. Potentilla canadensis, Spiranthes 
cernua, Sabatia angularis, Helianthemum, Agrimonia 
parviflora, Ceanothus, Viola sp., Poa sp., Panicum sp., 
Syntherisma sp. and others. The Botrychium was 
growing commonly in a moss I took to be a species of 
Polytrichum or something like it. te ‘ 
I might say this is the first instance where I have 
found either B. obliquum or dissectum as common. I 
have never seen B. dissectum before except as an occas- 
ional plant. The same with B. obliquum, except in 
flat woods in the southern part of the state where it 
sometimes is found in goodly numbers.—C. C. DeEaM,

swered in a recent number of the Journal, will in all
