A library of begonia and other plant information gathered by Michael Ludwig and donated by Carrie Karegeannes, Thelma O'Reilly, Rudy Ziesenhenne and others.

Founded by Michael Ludwig January 2006 This is a dream I, Michael Ludwig, never foresaw when I started joining plant societies in 1976. A world full of research materials, past and present, of Begonias and other plants that I love and grow, at my finger tips. I've inherited lifetimes of work from some of the greatest minds to study begonias and I look forward to adding my own studies as well and s

The genus Oreocharis is a species-rich group within the family Gesneriaceae and represents an excellent model system for evolutionary studies. However, taxonomic understanding of this genus remains insufficient, resulting in several unresolved issues. In this study, we focus on two species groups within Oreocharis—the O. argyreia group and the O. auricula group—each of which presents distinct taxonomic challenges. To address these, we conducted detailed morphological comparisons and statistical analyses, along with phylogenetic analyses based on dense population-level sampling. Our results support abolishing the variety O. argyreia var. angustifolia within O. argyreia but establishing a new species of O. nanlingensis to accommodate specimens of this variety collected from the broader Nanling mountains region. In addition, our findings suggest that O. auricula var. denticulata should be treated as a synonym of O. magnidens. We provide final taxonomic treatments, amended descriptions, photographs, and a distribution map for the relevant taxa.

Sinningia pampeana is a new rupicolous species from the rocky outcrops of the biome in southern and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii. Sinningia pampeana is restricted to rock outcrops within the Pampa grasslands, where populations are threatened by grazing, habitat degradation, and potential mining activities. Given the current uncertainty regarding its distribution and sampling completeness, a preliminary conservation assessment of ‘Data Deficient' (DD) is proposed under IUCN criteria.


Sinningia pampeana G.E.Ferreira & Chautems sp. nov.

Etymology: The specific epithet ‘pampeana' refers to the Pampa biome, characterized by grasslands and rocky outcrops across southern Brazil, Uruguay, and Argentina. The name derives from the Quechua word ‘pampa', meaning ‘plain' or ‘open field'.
