A Systematic Approach To Subtribe Loliinae (Poaceae: Pooideae) Based On Phylogenetic Evidence, Pilar Catalán, Pedro Torrecilla, José A. López-Rodríguez, Jochen Müller, Clive A. Stace Dec 2007

A Systematic Approach To Subtribe Loliinae (Poaceae: Pooideae) Based On Phylogenetic Evidence, Pilar Catalán, Pedro Torrecilla, José A. López-Rodríguez, Jochen Müller, Clive A. Stace

Aliso: A Journal of Systematic and Floristic Botany

Loliinae (Poaceae, Pooideae) encompass a large group of genera closely related to Festuca, the largest genus in the subtribe, which as traditionally circumscribed has been shown to be highly paraphyletic. In this investigation we combined molecular and morphological data representing 20 genera of Loliinae and closely related subtribes. Combined analysis of nucleotide sequences from the nuclear ITS and chloroplast trnL–F regions and structural characters recovered a consensus topology that shows Loliinae to be monophyletic and possessing two main clades—the fine-leaved Festuca clade that includes Ctenopsis, Micropyrum, Narduroides, Psilurus, Vulpia, and Wangenheimia, and …


Variability Of Bluegrass (Poa) In Siberia, Marina V. Olonova Dec 2007

Variability Of Bluegrass (Poa) In Siberia, Marina V. Olonova

Aliso: A Journal of Systematic and Floristic Botany

Siberian bluegrass (Poa) includes a number of polymorphic species such as P. arctica s.l., P. nemoralis s.l., P. palustris s.l., P. pratensis s.l., P. sibirica s.l., and P. smirnovii s.l., plus numerous hybrids and purported derivatives (e.g., P. attenuata s.l., P. glauca s.l., P. urssulensis s.l.). In Siberia Poa is represented by morphologically isolated species and hybrid-apomictic complexes, including both distinct species and taxonomic groups of obscure rank. Section Stenopoa is especially rich in these complexes. Most of the key morphological characters used in the taxonomy of bluegrass vary as much within populations as among populations and thus …


Phylogeny Of Triticeae (Poaceae) Based On Three Organelle Genes, Two Single-Copy Nuclear Genes, And Morphology, Ole Seberg, Gitte Petersen Dec 2007

Phylogeny Of Triticeae (Poaceae) Based On Three Organelle Genes, Two Single-Copy Nuclear Genes, And Morphology, Ole Seberg, Gitte Petersen

Aliso: A Journal of Systematic and Floristic Botany

Triticeae are renowned for their complicated taxonomy, but their phylogeny is equally intricate and perplexing, and remains largely unresolved. Based on morphology and nucleotide sequences from two plastid genes (rbcL, rpoA), one mitochondrial gene (coxII), and two single-copy nuclear genes (DMC1, EF-G), the most comprehensive hypothesis (both with respect to taxa and data points) of the phylogeny of diploid Triticeae to date is presented. The incongruence length difference tests clearly indicate that the four logical data partitions (morphology and the three genome compartments) are mutually incongruent, except the mitochondrial and nuclear sequences. …


A Brief Nomenclatural Review Of Genera And Tribes In Theaceae, Linda M. Prince Jul 2007

A Brief Nomenclatural Review Of Genera And Tribes In Theaceae, Linda M. Prince

Aliso: A Journal of Systematic and Floristic Botany

The angiosperm family Theaceae has been investigated extensively with a rich publication record of anatomical, cytological, paleontological, and palynological data analyses and interpretation. Recent developmental and molecular data sets and the application of cladistic analytical methods support dramatic changes in circumscription at the familial, tribal, and generic levels. Growing interest in the family outside the taxonomic and systematic fields warrants a brief review of the recent nomenclatural history (mainly 20th century), some of the classification systems currently in use, and an explanation of which data support various classification schemes. An abridged bibliography with critical nomenclatural references is provided.

Patterns Of Floral Structure And Orientation In Japonolirion , Narthecium, And Tofieldia, Margarita V. Remizowa, Dmitry D. Sokoloff, Paula J. Rudall Jan 2006

Patterns Of Floral Structure And Orientation In Japonolirion , Narthecium, And Tofieldia, Margarita V. Remizowa, Dmitry D. Sokoloff, Paula J. Rudall

Aliso: A Journal of Systematic and Floristic Botany

Floral evolution requires reassessment in basal monocots, including species formerly assigned to Melanthiaceae, in the light of recent developments in the molecular phylogenetics of monocots. We have investigated flowers of Tofieldia (Tofieldiaceae), Japonolirion (Petrosaviaceae), and Narthecium (Nartheciaceae). We confirm Engler's (1888) hypothesis that orientation of lateral flowers in monocots is dependent on presence and position of additional phyllomes on the pedicel. The type of floral orientation that occurs in Tofieldia is unusual for monocots, since the additional phyllomes are represented by calyculus scales rather than a bracteole, and the outer whorl tepals are initiated alternating with the calyculus scales. In …


Phylogenetic Analyses And Biogeography Of Trilliaceae, Susan B. Farmer Jan 2006

Phylogenetic Analyses And Biogeography Of Trilliaceae, Susan B. Farmer

Aliso: A Journal of Systematic and Floristic Botany

Trilliaceae are plants of North Temperate forests with a holarctic distribution and a high degree of endemism. Molecular phylogenetic analyses are presented in order to examine the tribal, generic, and species-level classification of the family. These molecular studies, and earlier morphological studies, support the placement of the genus Pseudotrillium as basal in the family and sister to the tribes Trillieae and Parideae, which are monophyletic sister groups. Trillidium (Trillium) govanianum provides an unresolved problem: morphologically it is included within Parideae, but molecular data place it within Trillium as sister to T. undulatum. Within tribe Trillieae, clades are …

Does The Monocot Mode Of Leaf Development Characterize All Monocots?, Geeta Bharathan Jan 1996

Does The Monocot Mode Of Leaf Development Characterize All Monocots?, Geeta Bharathan

Aliso: A Journal of Systematic and Floristic Botany

Patterns of early leaf development in monocots are analyzed in a phylogenetic context. Recent developmental and phylogenetic studies enable this reevaluation of the leaf base model of the developing monocot leaf. Two questions are addressed: a) is the presence of the Vorläuferspitze (fore-runner tip) invariably correlated with development of the lamina from the lower leaf zone? and b) was the ancestral monocot characterized by the leaf base mode of development? Scanning electron microscopic observations are made of young primorida using the mold and cast method. These data are combined with data from the literature and examined in a phylogenetic context …
