Iliamna remota Greene (Kankakee mallow, Malvaceae) is listed as endangered in Illinois and is endemic to Langham Island in the Kankakee River, Kankakee County, Illinois. Information on ways to break seed dormancy of I. remota would be useful for restoration and management. The purpose of this study was to determine if hot water at different temperatures and for different lengths of time would break seed dormancy. Seeds were dipped for 60 seconds into water at 70, 80, 90 or 100 degrees C with 22 degrees C dips as a control. In another trial, seeds were dipped into 80 degrees C …

Little is known about the reproductive biology of Stylisma pickeringii var. pattersonii, an endangered plant in Illinois occurring in only three counties (Cass, Henderson, and Mason). The objective of this study was to estimate flower densities and temporal (time of day and seasonal) differences in insect visitation to flowers of S. pickeringii in 2002 for native populations in Henderson and Mason Counties. A 50 m transect was located where S. pickeringii was most abundant and quadrats (0.25 m2) were placed on alternate sides of the tape measure at every meter at random distances from the transect. The number of flowers …

Eastern Illinois University was established in 1899, and from its beginning the importance of the botanical sciences was recognized. Two terms of botany were required for the four year program. Dr. Otis W. Caldwell, a botanist, was one of the original faculty members. He taught all of the biology courses and initiated the acquisition of a greenhouse. Caldwell was the first in a series of talented and dedicated botany professors including Edgar N. Transeau, Ernest L. Stover, Hiram F. Thut and John E. Ebinger. These and many other professors incorporated a field component into almost all classes. This dedication to …
