175 
nearly linear-lanceolate leaves, in western Nebraska and in the Black Hills of South 
Dakota. Dismal River, near Plummer Ford, July 6 to 8; Forks of Middle Loup, 
July 27; sand hills northeast of Whitman, July 29; Mullen, July 18 (No, 1509). 
2. A stouter form, hirsute all over; leaves ovate or oblong-ovate. Plummer Ford, 
July 4; Mullen, July 19; Dismal River, July 27 (No. 1433). 
3. A very stout form with purplish stem, hirsute all over, and with broad leaves, 
the lower broadly ovate, obtuse. Forks of Middle Loup, July 27 (No. 1810). 
4. A few specimens with thick and fleshy leaves, hirsute, especially on the ribs; 
stem densely hirsute, panicle crowded. Mullen, July 18 (No. 1799). 
Allionia nyctaginea Mx. I'l. i, 100 (1803). 
Not common in the sand-hill region, Plummer Ford, July 5; Mullen, July 20 
(No. 1496). 
Abronia fragrans Nutt.; Hook. Kew Journ. Bot. v, 261 (1853). 
Planted from seeds collected in the neighborhood; but I did not see any wild 
plant. Farther west it is very common. Thedford, June 19 (No. 1263), 
AMARANTHACEAI. 
Amaranthus retroflexus L. Sp., V1. ii, 991 (1753). 
In an old field: Mullen, July 18 (No. 1798), 
Amaranthus blitoides Wats. Proc. Amer. Acad. xii, 273 (1877). 
The stem is often more or Jess succulent. Thedford, June 21; Mullen, July 18 (No, 
1291). No. 1695 is a form with smaller leaves and the peduncles more or less thick- 
ened; road: Mullen, July 14). 
Amaranthus albus L. Sp. Pl. ed. 2, ii, 1404 (1763). 
In my specimens the seeds are evidently not rugose. Thedford, August 26; north- 
east of Whitman, July 29 (No. 1614). 
Amaranthus torreyi! (Gray) Benth.; Wats. Bot. Cal. ii, 42 (1880); Amblogyne 
torreyi Gray, Proc. Amer. Acad. v, 167 (1861), 
Common in the sand hills along Dismal River, especially around Plummer Ford. 
July 8 (No. 1370). 
This has been confused with Acnida tuberculata. The leaves are thicker, more 
veiny, obovate to ovate, obtuse, but mucronate, resembling those of Amaranthus 
blitoides. On the sand hills, Natick, June 20; Plummer Ford, July 8 (No. 1370). 
Acnida tuberculata Moq. in DC. Prodr. xiii, pt. ii, 277 (1849). 
The form common in eastern Nebraska with large thin leaves, lanceolate to oval, 
generally tapering at both ends, was growing on lowlands: Forks of Middle Loup, 
July 29; northeast of Whitman, August 1; West Cody’s Lake, August 10 (No. 1674). 
At Plummer Ford, July 8, was found a similar form, but with narrowly oblong to 
lanceolate, mucronate leaves, and the lower fertile flowers in small heads (No. 1513). 
In the dry alkaline lakes west and north of Whitman was found a low-branched 
form, with small leaves and reddish stems and flowers, July 31 and September 20 
(No. 1778). 
Freelichia floridana (Nutt.) Moq. in DC. Prodr, xiii, pt. ii, 420 (1849); Oplotheca 
Jfloridana Nutt. Gen. ii, 79 (1818). 
Mr. J. M. Holzinger has united this with F. gracilis. As they present themselves 
in this state, however, they are distinct. In /’. floridana the wings of the fruiting 
calyx are erose-dentate, not spiny except the lower teeth; in /. gracilis the teeth all 
become spines: Mullen, July 24 (No. 1594). In the sand hills near Plummer Ford, 
August 21, i found a giant form, 10 to 12 dm, high, with bracts nearly black in age, 
and large leaves, somewhat over 1 dm. in length (No. 1838).
