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.
Takhtajan, one of the foremost authorities on flowering plant evolution, has brought together from the literature and his own studies interpretations of the origin and evolution of various vegetative and reproductive parts of flowering plants. Starting with growth habit, he continues through leaf and stem structure, including the origin of vessels, sieve tubes, and rays, to flowers. After tracing the possible origin of the flower, he discusses in detail the sepals, petals, stamens, and carpels, accounting for their variations in number of parts, fusion, position, and structure. The evolution and origin of the micro- and megagametophytes and the development of triple fusion are considered. The book ends with the developmental sequence of the fruit and seed types. Each chapter has its own extensive bibliography. Takhtajan has produced a book that will be essential in the library of any college where plant evolution is considered.-C. T.

Buy (Botany) Plant Taxonomy And Ecology (Major) e-Book in English Language for B.Sc 2nd Semester KUK/CRS University NEP-2020 By Thakur publication.
This book presents a global and interdisciplinary approach to plant ecology, guiding students through essential concepts with real-world examples.
Taxonomy is one of the oldest biological disciplines. This book presents an account of general principles and aims of taxonomy in a comprehensive manner. It has been written mainly to cater the needs of undergraduate students pursuing courses in Botany/Life Sciences/Plant Sciences, but it will be useful for postgraduate students of these disciplines as well. The book gives a critical account of the important systems of classification and salient features of the APG II (Angiosperm Phylogeny Group, 2003) system of plant taxonomy. It mentions the important rules of plant nomenclature, and various codes of nomenclature including the latest Vienna Code of 2006. Further, it discusses the usefulnes...

A vividly illustrated meeting with thirty plants and their inspiring namesakes Shakespeare famously asserted that “a rose by any other name would smell as sweet,” and that’s as true for common garden roses as it is for the Megacorax, a genus of evening primroses. Though it may not sound like it, the Megacorax was actually christened in honor of famed American botanist Peter Raven, its name a play on the Latin words for “great raven.” In this lush and lively book, celebrated botanist Sandra Knapp explores the people whose names have been immortalized in plant genera, presenting little-known stories about both the featured plants and their eponyms alongside photographs and botanical ...
