M uhlenbergia includes 151 species of mostly New World origin; 133 species are indigenous to North America [although many of these range to Central America (33) and South America (14)]; 38 species occur in Central America (a single species is endemic); 25 species occur in South America (10 are endemic); and only six endemic species are known to occur in southern Asia. No modern subgeneric classification within the genus exists and species relationships are not clear. An anatomical survey of the… Expand
Phylogenetics of Muhlenbergiinae (Poaceae: Chloridoideae, Cynodonteae) based on ITS and trnL-F DNA sequences
TLDR
A phylogenetic study of Muhlenbergiinae based on parsimony analysis of DNA sequences of the nuclear ribosomal internal transcribed spacer region and chloroplast suggests two subtypes of C4 photosynthesis, NADME and PCK, are thought to occur in Mhlenbergia. Expand
A phylogeny and classification of the Muhlenbergiinae (Poaceae: Chloridoideae: Cynodonteae) based on plastid and nuclear DNA sequences.
TLDR
The phylograms suggest that Muhlenbergia originated in North America because the sister (Sohnsia filifolia and Scleropogoninae) is composed of predominantly North American species. Expand
Revision of Muhlenbergia (Poaceae, Chloridoideae, Cynodonteae, Muhlenbergiinae) in Peru: classification, phylogeny, and a new species, M.romaschenkoi
TLDR
A taxonomic treatment, phylogeny based on analysis of six DNA sequence markers and classification of Muhlenbergia for Peru is given, finding that the type of Podosemumangustatum clearly aligns with what was referring to as the hybrid between this species and M.rigida. Expand
MUHLENBERGIINAE (POACEAE: CHLORIDOIDEAE: CYNODONTEAE): FROM NORTHEASTERN MÉXICO
TLDR
A taxonomic treatment of the subtribe Muhlenbergiinae for northeastern Mexico (Coahuila, Nuevo Leon, and Tamaulipas) is given and a brief discussion indicating relationships among all species of MuhLenbergia in northeastern Mexico are provided. Expand
Muhlenbergia tarahumara (Poaceae: Choridoideae: Cynodonteae: Muhlenbergiinae), a new species from Chihuahua, Mexico
TLDR
Based on morphological and phylogenetic analysis of plastid and nuclear dna sequence data, it is concluded that the new species is sister to the aegopogon clade that is nested within a clade of species in Muhlenbergia subgen. Expand
Phylogeny of Muhlenbergia subg. Pseudosporobolus, including M. spatha (Poaceae, Chloridoideae, Cynodonteae, Muhlenbergiinae) now found in Zacatecas, Mexico
TLDR
A molecular phylogeny emphasising species in M. spatha is presented, using sequence data from two plastid markers (rpl32-trnL and rps16 intron) and nrDNA ITS to clarify affinities of the diminutive annual. Expand
A new species of Sporobolus (Poaceae, Chloridoideae) from Trindade Island, Brazil, with comments on the distribution of the genus in the South Atlantic
Sporobolus nesiotioides (Poaceae) is described as a new species from Trindade Island, Brazil, using morphological and anatomical characters. The species has affinity with the extinct S. durus fromExpand
A classification of the Chloridoideae (Poaceae) based on multi-gene phylogenetic trees.
TLDR
The maximum likelihood and Bayesian analysis of DNA sequences provides strong support for the monophyly of the Chloridoideae; a new tribal and subtribal classification for all known genera is proposed. Expand
Author ' s personal copy A classification of the Chloridoideae ( Poaceae ) based on multigene phylogenetic trees
We conducted a molecular phylogenetic study of the subfamily Chloridoideae using six plastid DNA sequences (ndhA intron, ndhF, rps16-trnK, rps16 intron, rps3, and rpl32-trnL) and a single nuclear ITSExpand
The paleoecological significance of stable carbon isotopes in lake sediments from the Chirripo Paramo of Costa Rica
The high elevation paramos of Costa Rica are dominated by C3 grasses (primarily bamboo) and evergreen shrubs; however, the high altitude C4 grass Muhlenbergia flabellata may dominate suitableExpand

Muhlenbergia, Subgenus Muhlenbergia (Gramineae) in North America
Muhlenbergia, subgenus Muhlenbergia (Gramineae, subfamily Eragrostoideae), consists of a group of usually rhizomatous, leafy, mesic grasses confined largely to eastern temperate North America, theExpand
Muhlenbergia aguascalientensis (Poaceae: Chloridoideae: Eragrostideae), a new species from Mexico
TLDR
A distinct taxon belonging to this complex was found during an examination of herbarium specimens at HUAA to complete the monographic descriptions of the Muhlenbergia montana complex, and to make a floristic study of the grasses from Aguascalientes. Expand
A chloroplast DNA analysis of Chaboissaea (Poaceae: Eragrostideae)
TLDR
Cladistic analysis indicates that Chaboissaea subbiflora is the sister to the remaining three species in the genus, followed by C. atacamensis and C. ligulata, both of which are extremely closely related and differ by only four autapomorphies in the latter. Expand
Correlation between generated morphological character data and flavonoid content of species in the Muhlenbergia montana complex
TLDR
A phenetic comparison of the morphological and chemical features suggests a different rate of divergence for chemical and morphological characters among species in this closely related group of taxa. Expand
Allelic variation in the amphitropical disjunct Muhlenbergia torreyi (Poaceae: Muhlenbergiinae)
TLDR
It seems likely that Muhlenbergia torreyi has dispersed to South America recently, because the populations there are less variable, and the genetic variation is slightly greater in North America than in South America. Expand
C4 acid decarboxylation type in Eragrostis (Poaceae) patterns of variation in chloroplast position, ultrastructure and geographical distribution
TLDR
NAD-ME-like species are numerically and proportionally dominant where rainfall is < 30 cm year−1, and as many species occur in high as in low rainfall areas as well as in relatively humid coastal and subcoastal areas. Expand
C4 Grasses: an Anatomical Criterion for Distinguishing Between NADP-Malic Enzyme Species and PCK or NAD-Malic Enzyme Species
TLDR
The likely C4 type of 255 biochemically-untyped grass species was deduced by direct observation or from Metcalf's anatomical descriptions and all 124 C4 species examined, including C3 eu-panicoids, proved to be XyMS+. Expand
