The pappus is white or sordid, finely papillose under the lens, which makes the 
distinction between Lygodesmia and Stephanomeria still smaller. Perhaps the two 
should make one genus. Dismal River, June 27; Mullen, July 17 (No. 1584). 
Nothocalais cuspidata (Pursh) Greene, Bull. Cal. Acad., ser. 2, ii, 55 (1886) ; 
Troximon cuspidatum Pursh, FI. ii, 742 (1814). 
Only four small specimens in fruit, found west of Thedford, June 14 (No. 1252). 
Lactuca canadensis L. Sp. PI. ii, 796 (1753). 
Few of the upper leaves are pinnatifid and the panicle is sometimes more open. 
Plummer Ford, August 23; Thedford, September 12 (2 0. 1755). 
Lactuca ludoviciana (Nutt.) DC. Prodr, vii, 141 (1839); Sonchus ludovicianus Nutt. 
Gen. ii, 125 (1818). 
River bank, near Mullen, July 17 (No, 1555). A lower purplish form was growing 
on the hillsides, near Plummer Ford: July 6 (No. 1507). 
Lactuca pulchella (Pursh) DC, Prodr, vii, 134 (1839) ; Sonchus pulchellus Pursh, 
FI. ii, 502 (1814). 
Mullen, July 18; northeast of Whitman, August 2 (No. 1570). 
CAMPANULACES. 
Lobelia syphilitica L. Sp. PI. ii, 931 (1753). 
Not uncommon on South Dismal River, August 9 to 14 (No. 1680). 
Lobelia spicata hirtella Gray, Syn. Fl. ii, pt. i, 6 (1878). 
Rare: in a meadow 4 miles northeast of Whitman, August 1; Thedford, August 
26 (No. 1818). 
Legouzia perfoliata (L.) Britton, Mem. Torr. Club, v, 309 (1894); Campanula 
perfoliata L. Sp. Pl. i, 169 (17538). 
Legouzia Dur. is the oldest generic name that can be used, Pentagonia Sieg., Specu- 
lum Hall, and Specularia Heist. being older than 1753 and, as far as I have been able 
to find, not used between that date and 1782. On hillsides here and there: Thed- 
ford, June 17; Dismal River, June 29 (No. 1346). 
Campanula aparinoides Pursh, Fl. i, 159 (1814), 
Common in wet meadows throughout the region: Plummer Ford, July 3 and 4; 
West Cody’s Lake, August 10 (No. 1457). 
PRIMULACE. 
Androsace occidentalis Pursh, Fl. i, 187 (1814). 
Only three small specimens collected in a prairie-dog town southeast of Thedford, 
June 15 (1299). 
Naumburgia thyrsiflora (L.) Duby, in DC. Prodr. viii, 60 (1844); Lysimachia 
thyrsiflora L. Sp. Pl. i, 147 (1753) 
The flowers in my specimens are smaller than usual, and the teeth between the 
lobes of the corolla are obsolete. The leaves of all the specimens found near Thed- 
ford seemed to be hairy beneath. The apparent hairs, however, were probably a 
parasitic alga. Middle Loup River, near Thedford, June 14 to 16; 3 miles north- 
east of Whitman, July 29 (No, 1262). 
OLEACESA:. 
Fraxinus pennsylvanica Marsh. Arb. Amer, 51 (1785). 
This seems to grade directly into the next. Thedford, June 21 (No. 1839), 
Fraxinus pennsylvanica lanceolata (Borekhausen) Sargent, Silva Amer. vi, 50 
(1894); Fraxinus lanceolata Borck, Handb. Forstbot. i, 826 (1800).
