Leaf Anatomy And Systematics Of Polygaleae (Polygalaceae), Heather Wilber Dec 2013

Leaf Anatomy And Systematics Of Polygaleae (Polygalaceae), Heather Wilber

Undergraduate Honors Theses

Polygalaceae are comprised of approximately 1000 species found worldwide in a variety of habitats. Over half of the species in the family were traditionally grouped into the polyphyletic genus Polygala and need resolution. Leaves from 21 species in 13 genera within tribe Polygaleae were field collected or taken from specimens at the Missouri Botanical Garden Herbarium (MO) to find phylogenetically useful characteristics of the foliar anatomy. The leaves were rehydrated using concentrated ammonium hydroxide, embedded in paraffin, and sectioned at 10 μm thickness using a rotary microtome. To observe epidermal features, rehydrated leaves were also cleared using 3% potassium hydroxide. …

Survey Of Medicinal Herbs Of Central Illinois Prairie And Woodlands, Debra Ann Welch Jan 2013

Survey Of Medicinal Herbs Of Central Illinois Prairie And Woodlands, Debra Ann Welch

Masters Theses

Illinois has been named the "Prairie State" for good reason. When the pioneers discovered a vast sea of grasses and forbs, they thought the prairie infertile. However, they soon found out that the blacksoil prairie was composed of a rich diversity of plant species that could provide much of the medical and nutritional needs of everyday life. The medicinal uses of many prairie species have not only been tested throughout history, but today modern science has also discovered their therapeutic importance.

The purpose of this study was to survey prairie species growing in the central Illinois counties of Coles and …


Morphometric Study Of Variation In The Genus Galeopsis (Lamiaceae), Michael T. Hughes Jan 2013

Morphometric Study Of Variation In The Genus Galeopsis (Lamiaceae), Michael T. Hughes

Masters Theses

The genus Galeopsis L. of the family Lamiaceae, also known as hemp-nettle, grows naturally in Europe and Asia, with four species naturalized in North America. The number of real species is in doubt, because of conflict over whether certain taxa are species, subspecies, or synonyms. The genus consists of five to eight taxa. I studied flower and leaf size ratios to clarify the distinctions of taxa in Galeopsis. These data were analyzed statistically, using cluster analysis, Principal Components Analysis (PCA), and Analysis of Variance (ANOVA). The results indicated that although some measurements, such as leaf width in G. angustifolia, …
