The Role Of Red Leaf Coloration In Prey Capture For Pinguicula Planifolia, Jenna Annis, Janice Coons, Charles Helm, Brenda Molano-Flores

Faculty Research & Creative Activity

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).

A New Species Of Cyperus Section Incurvi (Cyperaceae) From Venezuela, Gordon Tucker

Faculty Research & Creative Activity

Cyperus fedoniae is described as a new species. It is known from a single collection from the lowlands of southern Venezuela. It is a member of section Incurvi. It is related to C. dichromeniformis and C. inops, from which it can be distinguished by its smaller size and features of spikelets and achenes. A distinctive feature is the arching culms which take root at the base of the spikelets.Cyperus fedoniae es descrito como una nueva especie. Se conoce de una sola muestra de las tierras bajas del sur de Venezuela. Es un miembro de la secci.n Incurvi. Est. relacionada con …

Aceraceae - Acer Griseum, Janice Coons, Nancy Coutant, Wesley Whiteside

Plants by Family

Acer griseum was first brought to North America in 1907 by Ernest Henry Wilson in the form of two seedlings that were collected from Hubei Province in China. These two original plants remain at the Arnold Arboretum in Boston, Massachusetts, and were the source of the first North American horticultural distribution of the plant in 1927 (Del Tredici 2007). It is a handsome plant with very showy bark and is becoming more popular and easier to obtain than it has been in the past.

Botany At Eastern Illinois University, Marissa C. Jernegan, Nancy Coutant, Janice M. Coons

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 …

Additions To The Flora Of Connecticut, Gordon C. Tucker

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 …

Bulletin 200 - Trees And Shrubs Of The Campus And East Central Illinois, Ernest Stover

Eastern Illinois University Bulletin

The keys to the trees, shrubs and vines have been revised

in an attempt to make them more usable for the beginning student.

The keys to several of the genera, pines, oaks, ashes, willows,

etc., have been rewritten and species added that were not

in the previous printings.

The key to the trees in winter has been added hoping that it

will be helpful to both teachers and students. The identification

of trees without their leaves during the winter is not only interesting

but useful.

The identification of plants is but one phase of their study.

Botany is the basic …
