Book Review — Delmarva Lichens: An Illustrated Manual

Author : Erin A. Tripp

Delmarva Lichens: An Illustrated Manual, by James Lendemer and Nastassja Noell, is a much-welcomed contribution that highlights the lichen and allied fungal diversity of the greater Delmarva Peninsula area. Delmarva, which is far easier than saying “the region encompassed by portions of Deleware, Maryland, and Virginia,” is admittedly among the more ecologically disturbed regions for …


Taxonomy, Distribution, and Lectotypification of Two Rare, Southern Appalachian Saxifrages, Micranthes careyana and M. caroliniana

Author : Max S. Lanning

Additional Authors : Katherine G. Mathews

Taxonomists have traditionally distinguished two very similar Southern Appalachian endemic herbs, Micranthes careyana and M. caroliniana, by differences in four floral characters: sepal orientation, filament shape, petal coloration, and fruit length. Yet identification in the field and the herbarium has proven difficult, which is problematic for monitoring populations and determining rarity. The goal of this …


Contrasting Pollination Systems of Wild Unction and Devil’s Potato Root (Apocynaceae) on San Salvador: Preliminary Observations and Analyses

Author : Suzanne Koptur

Additional Authors : Tatyana Livshultz, Gretchen Ionta, Ching-Wen Tan,

Apocynaceae display highly complex and diverse floral morphologies. Pollen dispersal units include monads (single pollen grains; e.g. Plumeria), tetrads (Apocynum), and pollen packaged in pollinia, e.g. Asclepias and Cynanchum (Fishbein et al. 2018). All species produce adhesive from the specialized apex of the gynoecium (the style-head). At anthesis, this adhesive may be amorphous or molded …


Investigations Into the Reproductive Biology of the Southern Appalachian Endemic Piratebush (Buckleya distichophylla): Pollination Biology, Fruit Development, and Seed Germination

Author : Ryan Huish

Additional Authors : Amy E. Faivre, Melissa Manow, Conley K. McMullen

Endemic to the mountains of Tennessee, North Carolina and Virginia, piratebush (Buckleya distichophylla, Santalaceae) is a rare, dioecious, hemi-parasitic shrub with a scattered and isolated distribution. Vegetative reproduction and few visible seedlings within the densest population of piratebush on Poor Mountain in southwest Virginia emphasize the need for research into this species’ reproductive biology to …


The Vascular Flora of Snake Creek Gorge in the Georgia Piedmont

Author : Toby N. Saunders

Additional Authors : David R. Morgan

ABSTRACT Snake Creek Gorge is in the Brevard Fault Zone of the Georgia Piedmont, USA. We conducted an inventory of the vascular plants of the gorge throughout the 2016 growing season in a 20 ha study area and additionally evaluated variation in community compositions in 91 100 m2 quadrats. We measured six habitat and community …


Seed Germination and Seedling Survival of Invasive Callery Pear (Pyrus calleryana Decne.) 11 Years After Fruit Collection

Author : Tziporah H. Serota

Additional Authors : Theresa M. Culley

ABSTRACT: The ability of seeds to persist long term and still germinate readily with substantial seedling survival are characteristics shared by many invasive plants, often leading to dominance of species in invaded sites. One rapidly spreading species in the United States is the Callery pear (Pyrus calleryana), which can form dense monocultures following bird dispersal …


Noteworthy Collection: Illinois 84(1)

Author : Debbie S. Newman

Additional Authors : William E. McClain, John E. Ebinger

A second population of Phemeranthus calycinus (Montiaceae, large-flowered rock pink) was confirmed for southwestern Illinois. This is the second site known east of the Mississippi River for this taxon. Phemeranthus calycinus (Engelm.) Kiger (Montiaceae) Monroe County: open, nearly level outcrop of Au Vase sandstone, 35 m x 85 m, adjacent to an unnamed tributary of …


Taxonomy, ecology, and distribution of the genus Rhododendron (Ericaceae) in South Carolina

Author : Charles N. Horn

ABSTRACT: Data from field trips and a survey of herbarium specimens was used to determine relative abundance of the ten known species of Rhododendron (Ericaceae) in each county of South Carolina. All counties were documented to contain at least one species. The western-most mountainous and upper piedmont counties of Oconee, Pickens, Spartanburg, and Greenville were …


Noteworthy Collections: West Virginia (84-1)

Author : James P. Vanderhorst

Additional Authors : Brian P. Streets, Elizabeth A. Byers, Greg Short, Patricia L. Faulkner, Rodney Bartgis

New state records or clarifications of state distribution are presented for twenty taxa of vascular plants growing in West Virginia. These include twelve species considered native but overlooked in the state, one hybrid between species native to North America, four species native to North America but believed to be introduced in the state, and three …
