STEVENS: NortH DAKOTA PLANTS: 95 
MALVA VERTICILLATA L. I have not seen the specimen 
which Bergman referred to this species but am inclined to think 
that it was M. borealis Wallm., which is the common plant at 
Fargo and other places in the state. A specimen of what seems 
to be M. crispa L. + was sent by A. G. Sorlie, Grand Forks, 
Oct. 10, 1916. 
EuPHORBIA Esuta L. Wahpeton, June 3, 1920, Geo. P. 
Wolf; Hazelton, July 15, 1919, in field of Bromus inermis; New 
Rockford, July, 1911, J. R. Campbell; Mona, June 5, 1914, 
Albert Graves; Ray, July 2, 1917, H. A. Nelson. In one field 
near Fargo patches are scattered over 20 acres. Apparently 
a bad weed, spreading by the roots. Time and manner of in- 
troduction unknown. 
} SILENE DICHOTOMA Ehrh. Edgeley, July, 25, 1917, 
Brenckle; Langdon, July 19, 1918; Regent, July 20, 1916, A. 
C. Goldtrap. In timothy fields. Plants grown from seed 
proved to be coarse biennials larger than S. noctiflora. 
+ SILENE Faparia (L.) Sibth. & Sm. Specimens determined 
by Paul C. Standley. 
Biennial; glaucous, much branched, 6-9 dm. high. Basal 
and lowest stem leaves narrowed at the base, tances stem leaves 
ovate, sessile; flowering stems dichotomous wit flower 
in the fork, each branch with several remote clusters of three 
to seven flowers each. Flowers about I cm. wide, white, opening 
at night; petals cleft to the throat, not appendaged, the lobes 
oblanceolate, rounded at the apex; calyx indistinctly fifteen- 
ribbed, closely investing the ovate horny capsule, but not 
especially enlarged in fruit 
Venturia, July 16, 1919; Oakes, July 18, 1919. Lower stems 
and leaves with very much the aspect of Vaccaria Vaccaria. 
A specimen in the herbarium of Dr. J. F. Brenckle was collected 
at Kulm by him in 1916, and he states that he had found the 
plant there previous to that date. Apparently well established 
at Oakes and Venturia along roadsides. Dr. Standley writes 
that this is probably the first time it has been collected in this 
country. 
+ LycuHnis ALBA Mill. Devil’s Lake, July 13, 1920. 
CHENOPODIUM 
For several years I have been interested in C. album and 
related forms, especially in regard to seed characters. The 
plants are rather difficult to collect as the seeds are slow in 
maturing and the lower leaves are likely to be lost by the time 
the fruiting branches are well matured. With respect to the 
adherence of the pericarp it is to be noted that it rubs off more 
easily in fresh material.
