Erysimum repandum L. 
This species, which we may call ‘spreading mustard,” 
has been abundantly introduced apparently in seeds 
of red clover on a farm near Zanesfield, Logan county, 
Ohio. Ohio is thought by Lyster H. Dewey, to whom 
I am under obligations for the determination in the 
first instance, to be the third state of the Union to be 
credited with this mustard, native in the eastern Med- 
iterranean region. It was collected near Philadelphia 
in 1877 as a ballast weed; again at South Bethlehem, 
Pa., in 1892 (?), and at Long Pine, Nebraska, in 1808. 
Specimens at Zanesfield were freely collected by the 
writer, June 16, 1900. 
Lespedeza angustifolia (Pursh) EIl. 
Sand soil, Neapolis, Fulton county, 1899. Lewis 
Schultz. 
Orobanche ramosa L. (7?) 
On roots of tobacco, Neville, Clermont county. Some 
features of the imperfect specimens collected after frost, 
point to O. Ludoviciana Nutt., which, however, so far 
as I know, has not been reported on tobacco, 
Gerardia Besseyana burgess. 
Wooster, O., 1899, J. W. T. Duvel. 
Aster roscidus Burgess. 
Aster undulatus L. 
Both on dry soils. 
Wayne county, 1899, Selby and Duvel. 
Neapolis, Fulton county, 1900, Selby. 
Lactuca Canadensis L. 
A striking variety, as it appears to the writer, charac- 
terized by the elongated naked stem below the inflo— 
rescence. The var. nudata is proposed for it. Williams 
county, 1899, Selby.
