Eragrostis obtusiflora (Poaceae, Chloridoideae), a species distributed from the southwestern United States to central Mexico, has long been recognized for exhibiting morphological and anatomical features atypical of Eragrostis. Phylogenetic analyses

Chloridoideae (chloridoid grasses) are a subfamily of ca. 1700 species with high diversity in arid habitats. Until now, their evolutionary relationships have primarily been studied with DNA sequences from the chloroplast, a maternally inherited organ

Based upon a specimen first collected by S. N. Stephenson, a new grass species, Distichlis bajaensis H. L. Bell, is described. Stephenson hypothesized that this specimen was a hybrid between D. littoralis and D. spicata. Analyses of sequences of nucl

The Distichlis clade comprises Distichlis (7 species), Monanthochloë (2), and Reederochloa (1). All species except D. distichophylla (endemic to Australia) and D. spicata (widespread in the New World) are restricted either to North or South America.

The phylogeny of Chloridoideae (Gramineae) was inferred from parsimony analyses of DNA sequences from two genomes-the chloroplast tmL intron, trnL 3' exon, and trnL-F intergenic spacer, and the nuclear ribosomal internal transcribed spacer region (IT

Optimal growth of euhalophytes requires moderate concentrations of salt and, in dicotyledons, is associated with succulence and accumulation of Na(+) in plant tissues. However, reports of salt-stimulated growth in monocotyledons are rare. Relative gr

From 1876 to 1880 in San Luis Potosi, Mexico, J. G. Schaffner made the first collections of a small grass that later was named Schaffnerella gracilis (Chloridoideae). The monotypic genus apparently was not encountered again by botanists until 2001, w

Swallenia alexandrae, Eureka Valley dune grass (Poaceae, Chloridoideae), is a narrow endemic known only from three localities in the Eureka Valley and adjoining Saline Range in the northern portion of Death Valley National Park (Inyo County, Californ
