2013 journal article
Evidence of population bottleneck in Astragalus michauxii (Fabaceae), a narrow endemic of the southeastern United States
Conservation Genetics, 15(1), 153–164.
author keywords: Astragalus; Bottleneck; Endemism; Genetic diversity; Microsatellites; Pinus palustris
TL;DR:
Although genetic factors can threaten rare species, maintaining habitats through prescribed burning, in concert with other interventions such as population augmentation or (re)introduction, are likely most critical to the long term survival of A. michauxii.

2011 journal article
Recent vicariance and the origin of the rare, edaphically specialized Sandhills lily, Lilium pyrophilum (Liliaceae): evidence from phylogenetic and coalescent analyses
MOLECULAR ECOLOGY, 20(14), 2901–2915.
author keywords: coalescence; divergence; edaphic; Lilium; Pleistocene; rarity
MeSH headings : DNA, Chloroplast / genetics; DNA, Plant / genetics; DNA, Ribosomal Spacer / genetics; Gene Flow; Genetic Speciation; Genetic Variation; Genetics, Population; Haplotypes; Lilium / genetics; Models, Genetic; North America; Phylogeny; Sequence Analysis, DNA; Species Specificity
TL;DR:
The rare Sandhills lily is investigated, which is endemic to seepage slopes in a restricted area of the Atlantic coastal plain of eastern North America, and a close relationship is established between L. pyrophilum and the widespread Turk’s cap lily, L. superbum.

2010 journal article
Evidence for range stasis during the latter Pleistocene for the Atlantic Coastal Plain endemic genus, Pyxidanthera Michaux
MOLECULAR ECOLOGY, 19(19), 4302–4314.
author keywords: amplified fragment length polymorphism; cpDNA; Diapensiaceae; phylogeography; Pleistocene; refugium
MeSH headings : Alleles; Amplified Fragment Length Polymorphism Analysis; DNA, Chloroplast / genetics; Genetic Variation; Genetics, Population; Haplotypes; Magnoliopsida / anatomy & histology; Magnoliopsida / genetics; Molecular Sequence Data; Phylogeography; Sequence Analysis, DNA
TL;DR:
It is demonstrated that the refugial paradigm is not always appropriate and GACP endemic plants, in particular, may exhibit phylogeographical patterns qualitatively different from those of other ENA plant species.

2008 journal article
Tripterocalyx carneus (Nyctaginaceae) is self-compatible
SOUTHWESTERN NATURALIST, 53(3), 403–406.
TL;DR:
An experiment on a natural population of Tripterocalyx carneus to determine whether this species is self-compatible showed that flowers that were bagged but not emasculated set viable fruit in the majority of cases.
