Additional Authors : Lee-Ann C. Hayek, Andrea Weeks

ABSTRACT Kosteletzkya pentacarpos (L.) Ledeb. (syn. 5 Kosteletzkya virginica (L.) C. Presl ex A. Gray) has been treated as a single variable species or as a species including four varieties: K. virginica var. althaeifolia, var. aquilonia, var. smilacifolia, and var. virginica. The aim of this study was to test the validity of formally recognizing these …

Perspectives on Chemotaxonomy: Molecular Data Confirm the Existence of Two Morphologically Distinct Species within a Chemically Defined Lepraria caesiella (Stereocaulaceae)

Author : James C. Lendemer

ABSTRACT Lepraria caesiella as currently circumscribed includes two sets of populations with different thallus morphologies. The populations are chemically identical but differ ecologically and are rarely sympatric. A phylogeny was inferred from ITS1, 5.8S, and ITS2 sequence data generated froma geographically broad sampling of the populations with each thallus type. Two strongly-supported clades were recovered …

Phylogenetics and Diversification of Syringa Inferred from Nuclear and Plastid DNA Sequences

Author : Jianhua Li

Additional Authors : Benjamin Goldman-Huertas, Jeffrey DeYoung, John Alexander III,

ABSTRACT Analyses of nuclear ribosomal DNA have suggested the paraphyly of Syringa with respect to Ligustrum, a hypothesis requiring further testing from other sources of data. In addition, relationships among lineages of Syringa have not been resolved. In this study, we used DNA sequences of two nuclear and five plastid regions to better resolve phylogenetic …

Vascular Plant Flora of Two Natural Areas in Wabash County, Indiana

Author : David J. Hicks

ABSTRACT The Kokiwanee (56 ha) and Hathaway (29 ha) preserves are located in northeastern Indiana. Both sites include gorges cut by tributaries of the Wabash River, which produce a range of microenvironments that are unusual for this part of Indiana. Floristic inventories were done from 2004 through 2011. Kokiwanee had 467 vascular plant species, while …

Biodiversity Data in the Information Age: Do 21st Century Floras Make the Grade?

Author : Michael W. Palmer

Additional Authors : J. Channing Richardson

ABSTRACT Floras, or documented lists of vascular plant species in a defined area, are widely used in biodiversity research and conservation, and represent a common type of publication in regional botanical and natural history journals. Although all floras present common types of information, there has not yet been a formal attempt to develop community standards …

Seeds of Eriocaulaceae of the United States and Canada

Author : Scott Zona

Additional Authors : Philip Davis, L.A.A.H. Gunathilake, Jeffery Prince, James W. Horn,

ABSTRACT A study of seed coat micromorphology, using both light microscopy and scanning electron microscopy, revealed characters of taxonomic significance and utility among the species of Eriocaulaceae of the United States and Canada. Our survey of nine native species of Eriocaulon, five Lachnocaulon, and one Syngonanthus revealed diversity in the shape and size of the …

Study of Understory Vegetation at The University of Mississippi Field Station in North Mississippi

Author : Rani Menon

Additional Authors : Marjorie M. Holland

ABSTRACT The University of Mississippi Field Station is a 300-hectare area located in the Eocene Hills of the interior coastal plain of the southeastern US. Twenty long-term monitoring plots were established in 1996 following a major ice storm. Plots were sampled for understory (vegetation less than 1.5 m height) vegetation from 1996 to 2008 to …

Stand Dynamics of a 46-Year Invasion by Phellodendron amurense Rupr. in an Eastern North American Forest

Author : Eric C. Morgan

ABSTRACT An invasion by Phellodendron amurense Rupr. (Amur corktree) provided an opportunity to examine the subsequent changes in the forest composition that took place since the invasion began. Through the removal of 278 individual trees of P. amurense, tree ring analysis allowed a re-creation of the forest over the 46 yr since the species first …
