98 STEVENS: NortH DAKOTA PLANTS 
by Bergman from Morton County (Bell 30) is undoubtedly A. 
speciosa Torr.; it is sterile but has the characteristic pointed 
leaves of that species. The specimen reported by Bergman as 
possibly a hybrid of the two species seems scarcely different 
from A. syriaca. 
+ ASCLEPIAS PuMILA (A. Gray) Vail. Mr. W. W. Eggleston 
has examined our material of A. verticillata L. and refers the 
following to A. pumila: Esther, Bell 542; Fleak, Bell 1370. 
} ACERATES LANUGINOSA (Nutt.) DC. Janesburg, Bell 3o, 
of Bergman’s catalogue should be referred to this species instead 
of to A. viridifiora Ell. 
+ VERONICA MARITIMA L. Kongsberg, Sept. 1918, Fred 
Schmidt, Jr. A few plants in a-grove of planted trees. Deter- 
mined by F. W. Pennell. 
CuscuTA ARVENSIS Beyr. The Logan County record is by 
Brenckle, Aug. 18, 1912. We have also the following records: 
McLeod, Bell 385: Valley City, July 26, 1913; Enderlin, Aug. 20, 
1918. Dr. T. G. Yuncker, who has examined portions of the 
Logan County and Valley City specimens, writes that he would 
call them C. pentagona Engelm. The other specimens seem to 
be the form which he calls C. calycina Engelm. The former 
were growing upon plants of the dry prairie, while the latter 
preferred those of riverbanks and similar localities. 
Cuscuta Gronovit Willd. Fargo, Aug. 14, 1890, Waldron, 
is the only specimen which I consider typical. When preparing 
my paper on Cuscuta (Am. Jour. Bot. 3: 185-188. 1916) I was 
unable to find fresh material, but all that I have found at Fargo 
since that time agrees better with what I had called C. plattensis 
A. Nels. The habitat of C. plattensis, as stated by Nelson, 
hardly indicates this plant and I become doubtful of its identity. 
Dr. Yuncker writes me that an examination of the type of C. 
plattensis shows my plant to be quite different, although the 
description of the species as given by Nelson agrees. He refers 
my specimens to C. Gronovii var. curta Engelm. Ina flax field at 
Ft. Ransom, where considerable damage was caused, this form 
and C. Coryli Engelm. were both present, sometimes separate 
and at others tangled together on the same host plant. The 
field was a small one next to the woods of the river.
