STEVENS: NorTH DAKOTA PLANTS IOI 
+ ASTRAGALUS PARVIFLORUS (Pursh) MacM.. Marmarth, 
July 3, 1918. Quite common on the higher parts of the hills. 
} HEpysARumM sp. Sentinel Butte, Aug. 0916, Brenckle, a 
single pod collected. Reported by Arthur (N. Am. FI. 7: 450. 
1921) as H. cinerascens Rydb. 
} EVONYMUS ATROPURPUREUS Jacq. Owego, Sept. 1916, 
R. A. Shunk. 
} Lomatium MAcROCARPUM (Nutt.) Cov. & Rose. Dunseith, 
May 18, 1918, Lunell, and fruits collected at Minot in June, 1910, 
seem properly referred to this species. 
{ Stcyos ancuLatus L. I have seen a specimen collected 
by A. H. Shunk along the Sheyenne River near Anselm. 
{| CAMPANULA SIBERICA L. Belfield, July 4, 1914, a single 
plant found in a field of Bromus inermis. 
} XANTHIUM PENNSYI.VANICUM Wallr. A specimen in the 
Gray Herbarium from Leeds, Aug. 21, 1902, Lunell, is referred 
by Millspaugh and Sherff (Field Mus. Nat. Hist. Bot. Ser. 4: 
33. I919) to this species. Some specimens of Xanthium 
collected along the river at Fargo in 1919, to show variations in 
burs, were determined by Sherff as X. italicum Mor. 
canadense of the Flora) and X. acerosum Greene, t with the com- 
ment that the latter was perhaps not distinct. 
{| CHRYSOTHAMNUS NAUSEOsUS (Pall.) Britton. Williston, 
Aug. 11, 1915, on the hills along the Missouri River about fifteen 
miles southeast of the city. A plant of quite different appear- 
ance from C. graveolens (Nutt.) Greene, which is common there 
and on the buttes in the bad lands—the crown low, and with 
gray branches only 1-2 dm. long. This is the plant referred by 
Lunell (Am. Mid. Nat. 5: 41. 1918) at my suggestion to C. 
formosus Greene, but it evidently is not that species. ; 
HELIANTHUS GIGANTEUS L. The form referred to in Berg- 
man’s Flora under this name is quite common in the central 
(and western?) part of the state, but I am as yet in doubt as 
to its status. It is evidently Lunell’s H. mitidus (Am. Mid. 
Nat. 1: 235. 1914). Specimens from Valley City and New 
Rockford were determined by Standley as H. tuberosus. The 
Fargo specimens are H. Maximiliani Schrad. 
HELIANTHUS GROSSE-SERRATUS Martens. The Fargo speci- 
men of the Flora is certainly H. Maximiliani. The stem 
is only slightly hispid above and the leaves are broader and more 
nearly flat than usual. The Kenmare specimen (Bergman 2744) 
belongs to the preceding form.
