100 STEVENS: NoRTH DAKOTA PLANTS 
+ CRYPTANTHA CALYCoSA (Torr.) Rydb. Bowman, June 23, 
1918, in loose burned clay around large boulders of the same 
material. 
AMSINKIA MeEnzigEsiI (Lehm.) Nels. & Macbr. A. imter- 
media F.& M. Rugby, July 7, 1917, and July 27, 1918,a number 
of plants along the railroad track near the station; the first col- 
lection in flower, the second in fruit. Bergman’s specimen from 
Pembina is evidently this species also, instead of A. lycopsoides 
Lehm. | 
+ LAMIUM AMPLEXICAULE L. Langdon, July 18, 1918, a 
quantity in a dooryard. 
+ DRACOCEPHALUM THYMIFLORUM L. Belfield, July 4, 1914, 
several plants in a field of Bromus inermis. Several other 
introduced plants were also in the field: Potentilla argentea L., 
Campanula sibirica L., Chrysanthemum Leucanthemum L. and 
Bromus tectorum L. To be consistent with Bergman’s nomen- 
clature this plant should perhaps be referred to Moldavica but 
I have not thought it desirable to make such a change at this 
time. The plant is different in appearance from D. parviflorum 
Nutt., being slender and having very small flowers. 
+ Lycopus communis Bicknell. Pleasant Lake, July 26, 
1912, Lunell; Anselm, Aug. 29, 1920 (common in alder swamps). 
The Anselm plant has been verified by P. A. Rydberg. 
} SALVIA LANCEOLATA Willd. In fields. Carrington, Aug. 
27, 1919; Mandan, Sept. 13, 1920. : 
CHAMAERHODOs ERECTA (L). Bunge. This was included in 
the seventh edition of Gray’s Manual, the record being appar- 
ently based on a specimen collected near Crookston, Minn. 
(Minnesota Bot. Studies 2: 584. 1901). I had thought that 
it might have been introduced in gravel as railroad ballast, but 
so far as I have been able to learn the locality mentioned is a 
gravel pit. It is probably one of the instances of a plains species 
occuring on the eastern edge of the Red River Valley. I have 
not seen the plant east of the hills along the Sheyenne River at 
Sheyenne and Valley City. : 
} CRATAEGUS MOLLIs T. & G. Fargo, May 26, 1917. One 
tree is in a thicket east of the fair grounds, and quite a number 
occur in a bend of the river two miles farther north. 
} Mepicaco FaLcaTta L. Oakes, July 18, 1919, a plant 
along the railroad tracks.
