Lithospermum angustifolium Mx. Fl. i, 130 (1803), 
Collected in fruit only, near Thedford, June 20 (No. 1389). 
Lithospermum gmelini (Mx.) Hitchcock, Spring Fl. Manhattan, 30 (1894); Bat- 
schia gmelini Mx. F1. i, 130 (1803). 
This is a true sand-hill species. Thedford, June 15 (No, 1355). 
Onosmodium molle Mx. F]. i, 133 (1803). 
If this and O. carolinianum are to be united as one species, as they very probably 
should be, O. molle is the older name, and the form it represents should be regarded 
as the type. Thedford, June 20 (No. 1365). 
CONVOLVULACES. 
Ipomcea leptophylla Torr. Pl. Frem. {4 (1853). 
On the prairies near Plummer Ford, July 8 (No. 1511). 
Cuscuta indecora pulcherrima (Scheele) Engelm. Trans. St. Louis Acad, i, No. 3, 
502 (1859); C. pulcherrima Scheele, Linniwa xxi, 750 (1848). 
The most common Cuseuta in the region: northeast of Whitman, August 1, host 
plants, Helianthus petiolaris, Rumex venosus; South Dismal River, August 14, host, 
Helianthus petiolaris; Mullen, September 19, hosts, Cycloloma atriplicifolia, Chenopo- 
dium leptophyllum, Corispermum hyssopifolium, and Polygonum ramosissimum (No. 
1634). Ina few specimens the corolla is smaller and the plant approaches the true 
C. indecora, Mullen, August 17; hosts, Psoralea lanceolata and Artemisia canadensis ; 
Thedford, August 19, host, Lotus americanus (No. 1694). 
Cuscuta coryli Engel. Amer. Journ. Sci. xliii, 337 (1842). 
More rare: South Dismal River, August 14; host, Salix cordata angustifolia. Thed- 
ford, August 26, host, Aster sp. (No. 1688). 
Cuscuta cuspidata Engelm. Bost. Journ. Nat. Hist. v, 224 (1845).

psilostachya (No, 1639). 
SOLANACE #2. 
Solanum nigrum L. Sp. Pl. i, 186 (1753). 
The specimens from-.Mullen, July 20, are tall, hairy, with the younger parts sub- 
canescent, Those from Thedford, June 21, are greener and with thin leaves (No. 
1385). 
Solanum triflorum Nutt. Gen, i, 128 (1818). 
The only places in which I have seen this plant growing are prairie-dog towns 
(see note, page 141). Thedford, June 21, August 19 (No, 1393), 
Solanum rostratum Dunal, Sol. 234 (1816), 
Rare in the region; I collected only one specimen and Mr. Tulen only a few: 
Thedford, September 12 (No. 1758). 
Physalis heterophylla Nees, Linnia, vi, 463 (1831); Physalis virginiana American 
authors, not Mill. Dict. ed. 8, No. 4 (1768), 
Under this I place several different forms. They appear to belong to one species, 
very probably the one named, but they differ somewhat from the form found in 
eastern Nebraska. One form is very low, only 1 to 1.5 dm. high, very glandular and 
with thick, cordate leaves. It is of such a character as one would expect P. heter- 
ophylla to assume in such a locality as the sand hills. Thedford, June 14 (No. 1287). 
Another form, more grayish and less ¢landular, was collected near Cody’s Lakes, 
August 11, and near Mullen, July 23 (No, 1808); a third, much taller, resembling 
more the true P. virginiana, but villose rather than viscid, was found on a hillside 
near Plummer Ford, July 3.
