Book Description
The genus Agave is distributed in the tropical and subtropical areas of the world and represents a large group of succulent plants, with about 200 taxa from 136 species, and its center of origin is probably limited to Mexico. It is divided into two subgenera: Littaea and Agave based on the architecture of the inflorescence; the subgenus Littaea has a spicate or racemose inflorescence, while plants of the subgenus Agave have a paniculate inflorescence with flowers in umbellate clusters on lateral branches. As the main conclusion of this study, a hypothesis rises from the described observations: frying pan-shaped chromosomes are formed by sister chromatid exchanges and a premature kinetochore movement in prophase II, which are meiotic aberrations that exist in these phylogenetic distant species, Agave stricta and A. angustifolia since ancient times in their evolution, and this may be due to genes that are prone to act under diverse kinds of environmental stress.

Book Description
New in paperback Spring 2004, this is an indispensable guide to agaves. The uses of agaves are as many as the arts of man have found it convenient to devise. At least two races of man have invaded Agaveland during the last ten to fifteen thousand years, where, with the help of agaves, they contrived several successive civilizations. The region of greatest use development is Mesoamerica. Here the great genetic diversity in a genus rich in use potential came into the hands of several peoples who developed the main agricultural center of the Americas. Perhaps, as the Aztec legends suggest, it was the animals that first showed man the edibility of agave. Evolution in use ranges all the way from the coincidental and spurious, through tool and food-drink subsistence with mystical overlay, to the practical specialties of modem industry and art. The historic period of agave will be outlined here as briefly as that complicated development will allow.

Book Description
The Term Systematic Botany Encompasses The Domain Not Only Of The Higher Plants, But Also Of The Lower Plants. Since It Is Not Possible To Treat Adequately The Various Plant-Groups Under A Single Volume, This Edition Is Restricted To A Discussion Of The Angiosperms. It Has Been Designed As A Textbook For The Undergraduate Students (Pass & Honours) Of All The Indian Universities And It Will Be Helpful To Postgraduate Students In Botany As Well As To The Study Of Agriculture And Allied Subjects. The Author Has Abandoned Bentham-Hookers System And Presented A New Scheme Of Angiosperm-Classification. Although The Latter Scheme, Like Any Other Envisaged Before, Has Its Shortcomings, It Represents The Most Probable Natural Relationship Among Flowering Plants.Almost All The Taxa Prevalent In The Indian Flora Have Been Dealt With, Covering 44 Orders And 193 Families. Generally, Each Order Has Been Discussed In The Light Of Phylogeny And With Emphasis On Its General Features, Circum Inter-Relationship, Origin And Means Of Identification Of Various Families (By Bracketed Keys). Those Families Prominent In The Countrys Flora Have Been Described Under Six Or Seven Different Heads, Depending On The Available Information. Though The Inconspicuous Ones Have Not Been Categorised Likewise, One Can Even Find In Them The Array Of Items Under Each Family Being Suitably Treated. Moreover, The Nomenclature Of Plants Have Been Checked And Brought Up-To-Date As Far As Possible. Part One Is An Expose Of Taxonomic Principles, While PartsThree And Four, Deal With The Dicotyledonous And Monocotyledonous Plants Respectively. Under Part Two, There Are Certain Specialised Topics Which Have A Bearing On The Study Of The Systematic Botany Of Angiosperms. A List Of Important Books And Papers Is Inserted At The End Of Each Part. In Brief, The Author Has Made Anattempt To Give A Complete Picture Of Angiosperm Systematics.
