Herendeen Premise of research. Discoveries of fossil flowers in Cretaceous rocks offer improved evidence for rela- tionships with living clades, but for more secure inferences formal phylogenetic analyses are desirable. We extend previous analyses of magnoliids, monocots, and basal eudicots to Aptian, Albian, and Cenomanian fossils related to the basal “ANITA” lines and Chloranthaceae. Methodology. We performed parsimony analyses of a morphological data set of Recent angiosperms and published fossils, with the arrangement of Recent taxa constrained to backbone trees based primarily on molecular data. Pivotal results. Not only Monetianthus (as previously inferred) but also Carpestella is nested within Nymphaeaceae, while Pluricarpellatia may be a stem relative of Cabombaceae or Nymphaeaceae. Anacostia (with Similipollis pollen) is nested within Austrobaileyales. -
Diversidad De Plantas Y Vegetación Del Páramo Andino
Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1). -

UNIVERSIDAD DE LOS ANDES FACULTAD DE CIENCIAS, DEPARTAMENTO DE CIENCIAS BIOLÓGICAS TRACING BACK THE POLLEN FOSSIL RECORD OF HEDYOSMUM (C HLORANTHACEAE ), A BASAL ANGIOSPERM CAMILA MARTÍNEZ AGUILLÓN Trabajo de grado para optar al título de Biólogo Director: Carlos Jaramillo, STRI Co-director: Santiago Madriñán, Universidad de los Andes Bogotá D.C., 2009 TRACING BACK THE POLLEN FOSSIL RECORD OF HEDYOSMUM (C HLORANTHACEAE ), A BASAL ANGIOSPERM ABSTRACT The Chloranthaceae family has been described as one of the oldest lineages within the angiosperms. Hedyosmum is the only Neotropical genus and is composed of approximately 45 species. The fossil record shows that the first apparition of the genus was in the Early Cretaceous (~120 Ma), followed by a time gap of 70 Ma during the Paleogene, where no fossil records of Hedyosmum were found. It is only until the Early Miocene when a new record associated with Hedyosmum: Clavainaperturites microclavatus is found. The association was established using only transmitted light microscopy. The aim of this study was to determinate the relationship between the fossil Clavainaperturites microclavatus from the Miocene and the extant genus Hedyosmum using transmitted light microscopy, scanning and transmitted electron microscopy. The quantitative characters were evaluated with a non-metric multidimensional scaling. Given the high morphological affinity of the pollen fossil with the extant Hedyosmum it is concluded that C. microclavatus belongs to Hedyosmum, and that the radiation of the genus could have occurred in Central and South America in the Early Miocene, before to the emergence of the Panamanian Isthmus and the rising of the Andean cordillera. Two hypotheses were suggested to explain the gap in the fossil record of the genus, a change in the pollination syndrome or/and a dramatic population decrease after the K/T event. -

Arts 48:153- Wood of the genus is primitive in its notably long scalariform perforation plates; scalariform lateral wall pitting of vessel elements; and the low ratio of length between imperforate tracheary elements and vessel elements. Pit membrane remnants are characteristically present to various degrees in perforations of vessel elements; this is considered a primitive feature that is related to other primitive recharacterization vessel features. Specialized features of Hedyosmum wood include septate fiber-tracheids with much Bull. 36:381-389. reduced borders on pits; vasicentric axial parenchyma; and absence of uniseriate rays (in wood of larger stems). Ray structure (predominance of upright cells) and ontogenetic change in tracheary element length are paedomorphic, suggesting the possibility of secondary woodiness in the genus. -
'Parasite Lost': Botanist Discovers Unusual Plant
Date: April 28, 2008 ‘PARASITE LOST’: BOTANIST DISCOVERS UNUSUAL PLANT MISSING SINCE 1985 (ST. LOUIS): Intensive field research and herbarium study leads the Missouri Botanical Garden in St. Louis to describe as many as 100 plant species a year that are new to science. The discovery of an entirely new genus is significantly rarer. Dr. George Yatskievych, scientist and curator in the Garden’s Science and Conservation Division, has successfully recovered and is studying such an undescribed genus: an unusual parasitic flowering plant that has lost its chlorophyll and depends entirely on its host tree for nutrients and water. Only one specimen of this “parasite lost” existed prior to Yatskievych’s research, found over 20 years ago and not seen since. In 1985, Dr. Wayt Thomas of the New York Botanical Garden had a chance encounter with a single specimen while collecting other plants in the Mexican state of Guerrero. The odd, orange- brown, fleshy-stemmed plant had a pinecone-shaped dense cluster of flowers. The late Dr. Larry Heckard of the University of California, a leading North American expert on parasitic plants, examined the specimen but was unable to identify even its plant family. Parasitic plants are extremely hard to study as pressed specimens, as they become brown and distorted during the drying process. Thus, the plant remained unidentified for more than 20 years, before eventually making its way through the scientific community to the Missouri Botanical Garden. As a Garden botanist, Yatskievych has performed taxonomic research on families of parasitic plants for the Flora of Missouri Project and the Flora of North America. -

Contribution to the Floristic Knowledge of the Sierra Mazateca of Oaxaca,Mexico
NUMBER 20 MUNN-ESTRADA: FLORA OF THE SIERRA MAZATECA OF OAXACA, MEXICO 25 CONTRIBUTION TO THE FLORISTIC KNOWLEDGE OF THE SIERRA MAZATECA OF OAXACA,MEXICO Diana Xochitl Munn-Estrada Harvard Museums of Science & Culture, 26 Oxford St., Cambridge, Massachusetts 02138 Email: [email protected] Abstract: The Sierra Mazateca is located in the northern mountainous region of Oaxaca, Mexico, between the Valley of Tehuaca´n-Cuicatla´n and the Gulf Coastal Plains of Veracruz. It is part of the more extensive Sierra Madre de Oaxaca, a priority region for biological research and conservation efforts because of its high levels of biodiversity. A floristic study was conducted in the highlands of the Sierra Mazateca (at altitudes of ca. 1,000–2,750 m) between September 1999 and April 2002, with the objective of producing an inventory of the vascular plants found in this region. Cloud forests are the predominant vegetation type in the highland areas, but due to widespread changes in land use, these are found in different levels of succession. This contribution presents a general description of the sampled area and a checklist of the vascular flora collected during this study that includes 648 species distributed among 136 families and 389 genera. The five most species-rich angiosperm families found in the region are: Asteraceae, Orchidaceae, Rubiaceae, Melastomataceae, and Piperaceae, while the largest fern family is Polypodiaceae.
