Hitchcock). Fremont county (A. S. Hitchcock). Sioux City, 
Council Bluffs, Keokuk, 1891 (P. H. Rolfs). 
BORRAGINACE^. 
Echium vulgare L. Ames, 1894 (G, W. Carver). Not since 
observed. 
CON VOL V UL ACE^ . 
Convolvulus arvensis. Ames. Since 1837 well established. 
Ladora, 1895 (John Hiltbrummer). Des Moines, 1896 (C. N. 
Page). Very likely occurs in other places. First introduced 
as a cultivated plant. This may become one of our most pesti- 
ferous of perennial weeds. 
SOLANACE^. 
Solanum carolinese L. This weed has been well established 
on the college farm since 1887. As it started in an experi- 
mental plot, I am inclined to think it was introduced acci- 
dentally with some cultivated plants. It has been reported to 
me from many other places in the state. Certainly showing an 
extension northward and that acclimation has occurred. 
The following are the localities for this state: 
Zearing, 1896 (J. S. Bartley). Indianola, 1895 (A. D. Field). 
Mapleton, 1895 (Abjh. Lamb). Story City (C. C. Johnson). 
Central City, 1894 (Herman Finson). Fayette, 1894 (Mrs. M. 
E. Williams). Logan, 1895, Council Bluffs, 1895. (L. H. P.) Pro- 
fessor Bessey informs me that he observed it here many years 
ago. It is well established at this point. Ogden, 1894 (John Wil- 
liams). Plattsville, 1894 (J. B. Studley). Des Moines, 1894. 
Woodbine (Erastus Childs, Geo. Phillips). Muscatine (F. Rep- 
pert). Keokuk, 1891 (P. H. Rolfs). Taylor county, 1894 (C. 
O. Pool). Grand Junction, 1890. 
Solanum rostratum Dunal. This weed has been reported 
from many widely scattered localities. It was not common in 
1887 or up to 1890, since Professor Hitchcock, a diligent col- 
lector, does not report it in catalogue of the Anthophyta and 
Pteridophyta of Ames, Iowa, 1891. It has been long known in 
western Iowa, as Professor Todd informs me. Ames, 1895 
(John Arrasmith, Turner McClain). Montezuma, 1895 (J. M. 
^ Bryan). Aspinwall, 1895 (C. H. Laughlin). Woodbine, 1895
