Systematics, Evolution, and Ecology of Melastomataceae by Renato Goldenberg,Fabián A. Michelangeli,Frank Almeda Pdf
This book presents a synthesis of critical new information for the Melastomataceae, one of the ten richest families among flowering plants with over 5,800 species that has its diversity highly concentrated in tropical or subtropical areas. It describes the family’s global diversity and distribution and summarizes recent advances in systematics, evolution, biogeography, reproductive biology and ecology.

Systematics and Phylogeny of Siphanthera (Melastomataceae) by Frank Almeda,Orbélia R. Robinson Pdf
This study represents the first attempt to evaluate generic and species limits in the South American genus Siphanthera by incorporating new information from macromorphology, pollen and seed micromorphology, chromosome cytology, a cladistic analysis, and distributional information. Available data provide a rationale for recognizing Siphanthera as a monophyletic genus of fifteen species with a bicentric distribution centered in the Brazilian Planalto, and the Guayana Highlands and contiguous areas. The monotypic genus Farringtonia has been merged with Siphanthera during this study and two new species are proposed here, S. todziae from the Amazon Basin and S. wurdackii from the Brazilian Planalto. The recent assignment of Siphanthera to the broadly defined tribe Melastomeae is called into question pending the results of a forthcoming family-wide multi-gene phylogenetic analysis. An evaluation of taxonomic characters used to recognize previous infrageneric groups has led to the abandonment of a formal sectional classification of the genus. Some major evolutionary trends in Siphanthera include: change from a perennial to an annual life cycle; change in foliar venation from basal acrodromous to loss of secondaries in one direction and change in the prominence of secondary veins and their pattern of divergence from the primary vein in another direction; reduction in inflorescence complexity from branched compound dichasia to congested capituliform inflorescences or few-flowered or solitary flowered inflorescences; change in petal shape from obovate with a rounded to acute base to more or less rotund petals with a clawed base; reduction in stamen number from eight fertile stamens to four fertile stamens; change in anther shape from elongate and subulate or rostrate with a small apical pore to ovoid or subrotund with a broad ventrally or dorsally inclined apical pore; and modification of capsule shape from essentially globose with a rounded apex to laterally compressed with a bilobed or notched apex. Species constituting the first diverging lineage in our cladogram suggest a possible Brazilian Planalto origin for the genus. Pathways to northward migration were opened via large areas of continuous savanna vegetation across the Amazon Basin that connected the Brazilian and Guayana Shields during climatic fluctuations of the Pleistocene. In a less likely alternative, the distribution of Siphanthera can be accounted for by vicariance of a widespread ancestor that spanned the Brazilian and Guayana Shields. In this scenario, the taxa that branch off from the first diverging clade in our phylogenetic tree could represent a geographic sequence of differentiation from the widespread ancestor and not a series of dispersal events. Present-day rain forest dominance of the Amazon Basin with its few and scattered savanna islands has largely isolated northern and southern populations of Siphanthera and appears to explain the prevailing bicentric concentration of species on the South American continent (publisher's description.
Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.
Plant Systematics is a comprehensive and beautifully illustrated text, covering the most up-to-date and essential paradigms, concepts, and terms required for a basic understanding of plant systematics. This book contains numerous cladograms that illustrate the evolutionary relationships of major plant groups, with an emphasis on the adaptive significance of major evolutionary novelties. It provides descriptions and classifications of major groups of angiosperms, including over 90 flowering plant families; a comprehensive glossary of plant morphological terms, as well as appendices on botanical illustration and plant descriptions. Pedagogy includes review questions, exercises, and references that complement each chapter. This text is ideal for graduate and undergraduate students in botany, plant taxonomy, plant systematics, plant pathology, ecology as well as faculty and researchers in any of the plant sciences. * The Henry Allan Gleason Award of The New York Botanical Garden, awarded for "Outstanding recent publication in the field of plant taxonomy, plant ecology, or plant geography" (2006) * Contains numerous cladograms that illustrate the evolutionary relationships of major plant groups, with an emphasis on the adaptive significance of major evolutionary novelties *Provides descriptions and classifications of major groups of angiosperms, including over 90 flowering plant families * Includes a comprehensive glossary of plant morphological terms as well as appendices on botanical illustration and plant description
