The genus (Solanaceae, Capsiceae) in Mexico and Guatemala.

, the third most species-rich genus in the Solanaceae, is distributed in both the New and Old Worlds and is especially diverse in Mexico. Here we provide an identification key, taxonomic descriptions, distribution maps, and illustrations of specimens, trichomes, flowers, and fruits for the 53 known taxa of Mexico and Guatemala. The new combination (Mill.

Diversity, distribution, development, and evolution of medullary bundles in Nyctaginaceae.

Premise: Medullary bundles, i.e., vascular units in the pith, have evolved multiple times in vascular plants.

A new species of Cissampelos (Menispermaceae) from Bolivia and Paraguay.

The new species Cissampelos arenicola M. Nee & R. Ortiz, from the Bolivian and Paraguayan Chaco is described, its affinities are discussed, and its preliminary conservation status is evaluated.

Reply to J. Samuels: Taxonomic notes on several wild relatives of Solanum melongena L.

The purpose of the study "Phylogeographic relationships among Asian eggplants and new perspectives on eggplant domestication" by Meyer et al. (2012) was to use new and expanded accession sets coupled with molecular data to evaluate possible scenarios of eggplant domestication with as little influence as possible from any previously published nomenclatural scheme, and taking into consideration multiple sources of evidence regarding the history of eggplant in Asia. Samuels (2013) disfavored this system and in his Letter to the Editor attempted to re-evaluate the results according to his system.

Description and molecular diagnosis of a new species of Brunfelsia (Solanaceae) from the Bolivian and Argentinean Andes.

Phylogeographic relationships among Asian eggplants and new perspectives on eggplant domestication.

The domestication history of eggplant (Solanum melongena L.) has long been debated, with studies unable to narrow down where domestication occurred within a broad region of tropical Asia. The most commonly hypothesized region is India, however China has an equally old written record of eggplant use dating ca.

Melothria domingensis (Cucurbitaceae), an endangered Caribbean endemic, is a Cayaponia.

The Neotropical genus Melothria (Benincaseae, Cucurbitaceae) is a small group of yellow- or white-flowered climbers with small to medium-sized fruits. In 1899, Alfred Cogniaux described a species from montane rainforest in Haiti as Melothria domingensis, presumably based on the overall similarity in habit, leaf shape, and fruit morphology of his incomplete herbarium material to other Central American Melothria species. Melothria domingensis is still rare in European and American herbaria and the species has never been studied in detail.

Genetic relationships and evolution in Cucurbita pepo (pumpkin, squash, gourd) as revealed by simple sequence repeat polymorphisms.

Genetic relationships among 104 accessions of Cucurbita pepo were assessed from polymorphisms in 134 SSR (microsatellite) and four SCAR loci, yielding a total of 418 alleles, distributed among all 20 linkage groups. Genetic distance values were calculated, a dendrogram constructed, and principal coordinate analyses conducted. The results showed 100 of the accessions as distributed among three clusters representing each of the recognized subspecies, pepo, texana, and fraterna.

Antioxidant capacities of ten edible North American plants.

The EtOAc extract obtained from ten edible North American plants, Acorus calamus, Clintonia borealis, Gaultheria shallon, Juniperus osteosperma, Opuntia polyacantha, Prunus americana, Prunus virginiana, Sambucus cerulea, Sorbus americana and Vaccinium parvifolium, were tested in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical assay. High antioxidant activity was obtained from the extracts of three fruits, Gaultheria shallon, Sambucus cerulea and Prunus americana and one extracted rhizome, Acorus calamus. Catechin and epicatechin, potent polyphenolic antioxidants, were identified in the EtOAc extracts of Gaultheria shallon and Sambucus cerulea by reversed-phase thin-layer chromatography (TLC) and reversed-phase high-performance liquid chromatography (HPLC).
