New records and other notes on North Dakota plants* 
O. A. STEVENS 
The present paper is supplementary to Bergman’s Flora of 
North Dakota (in Sixth Bien. Rept. Agr. Coll. Survey [1911- 
1912]. 1918) and, as such, will follow the same arrangement and 
nomenclature. The purpose is to record additional species, 
designated by a dagger (t), and other notes of special interest. 
During the years 1910 to 1920 I have had opportunity to visit 
nearly every part of the state and, incidental to economic work, 
to obtain many specimens of interest. Some of these were 
noted in the Flora and others have been reported by Lunell 
(Am. Mid. Nat. 4-6. 1917-1919). I have also included in the 
paper a few corrections which have come to notice and revised 
certain groups in which I have become especially interested. 
Where not otherwise stated, the specimens listed have been 
collected by myself. 
LEPIpIum RAMOsIssIMUM A. Nels. I do not know why 
Bergman reduced this to a synonym of L. densiflorum Schrad. 
The two species are very different and may be distinguished as 
follows: 
L. densiflorum. Annual, stem usually simple below and with 
several long racemes above; basal and lower stem leaves 
serrate; pods distinctly margined and broadest toward the 
apex. 
L. ramosissimum. Biennial, bushy branched from the base; 
asal and lower stem leaves pinnatifid, the lobes linear or 
oblanceolate; pods not margined above, elliptic in outline. 
The following specimens belong to L. ramosissimum: Tower 
City, Bergman 870; Valley City, Aug. 13, 1912, (first year 
rosettes); Courtenay, June 20, I9IT; Kensal, July 26, 1915, 
(rosettes, also flowering stems) ; Manfred, July 12, 1913; Sykes- 
ton, July 15, 1891, Bolley; Sheyenne, July 4, 1908, Lunell; 
Leeds, Aug, I, 1912; Bathgate, July 22, 1892, Lee; Ganbetta; 
Bell 264; Rugby, Bergman 2611. This species is quite common 
throughout the central part of the state, growing about streets 
and dooryards rather than in fields. At Langdon on July 19, 
1918, I noticed the rosettes of L. ramoisssimum fairly covering
