Anthocyanins in the leaves of carnivorous plants are suggested to play a role inprey capture. In this study, we investigated the role of red leaf coloration (an indicator of anthocyanins)on prey capture using Pinguicula planifolia (Chapman’s Butterwort). Overall,red leaves had less prey (i.e., Collembola) than green leaves, suggesting that red colorationdoes not enhance prey capture for Chapman’s Butterwort. However, the frequent presenceof Collembola on leaves suggests that this plant species could be relying on other cues toattract prey (e.g., olfactory cues).

Faculty Research & Creative Activity
Eastern Illinois University was established in 1899, and from its beginning recognized the importance of the botanical sciences. Two terms of botany were required for the four year program. 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 of 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 the study …

Faculty Research & Creative Activity
Since the publication of the Connecticut checklist by Dowhan (1979), new state records have continued to appear. These were summarized by Mehrhoff (1995), including some made by Tucker ( 1987, 1991 ). Although geographically distant, the flora of Connecticut has continued to hold my attention since the publication of a flora of the southeastern part of the state (Tucker 1995). Over the past decade, I have made several collections that are new records for the state flora. These new records are reported in this paper, as well as a 1970 collection of Coronilla scorpio ides that was never added to …
