, a remarkable new species of the genus Saxifragasect.Irregulares (Saxifragaceae) from Guangxi, is described and illustrated herein. This new species morphologically differs from all known S.sect.Irregulares taxa by its greenish petals, verruculose sepals, and thick leathery leaf blade abaxially scarlet with white spots.

section subsection is a lineage of 12 species distributed mainly in the European Alps. It is unusual in terms of ecological diversification by containing both high elevation species from exposed alpine habitats and low elevation species from shady habitats such as overhanging rocks and cave entrances. Our aims are to explore which of these habitat types is ancestral, and to identify the possible drivers of this remarkable ecological diversification.

A major challenge in evolutionary biology is to understand how complex traits of multiple functions have diversified and codiversified across interacting lineages and geographic ranges. We evaluate intra- and interspecific variation in floral scent, which is a complex trait of documented importance for mutualistic and antagonistic interactions between plants, pollinators, and herbivores. We performed a large-scale, phylogenetically structured study of an entire plant genus (, Saxifragaceae), of which several species are coevolving with specialized pollinating floral parasites of the moth genus (Prodoxidae).

Two new 2,4'-epoxy-8,5'-neolignans (1 and 2), together with five known 7,9';7',9-diepoxylignans (3-7), were isolated from an ethyl acetate soluble portion of a hepatoprotective water decoction of Penthorum chinese. Their structures and absolute configurations were elucidated by extensive spectroscopic analyses and electronic circular dichroism (ECD) calculations. This is the second report of 2,4'-epoxy-8,5'-neolignans from plants.

Premise Of The Study: The use of multiple genetic regions from the nuclear genome, including low-copy markers, has long been recognized as essential to robust phylogenetic construction, addressing gene tree incongruence, and allowing increased resolution to test current taxonomy and resolve basic hypotheses about character evolution, biogeography, and other organismal traits of interest to biologists. Heuchera, the largest genus of Saxifragaceae endemic to North America, has presented an unusually difficult case for systematists with limited sampling in previous molecular studies. We used morphological and multilocus molecular phylogenetic data to test the monophyly of Heuchera, better resolve hypotheses of relationships, and test hypotheses of character evolution, biogeography, and diversification rates.
