This book is very useful to the researcher in the field of morpho-anatomical study of cypsela. It is also helpful to the students of BSc. and MSc. to know the details of cypselas. They can distinguish among different taxa of Asteraceae on the basis of cypselar morpho-anatomical study.It is useful to the separation of taxa in the species level. The researcher on the field of this study can observe detailed morpho-anatomical features of cypsela which is very useful to carry out their study.

In Asteraceae, a set of bracts are found as a whorl surround the base of the inflorescence, known as involucres. These bracts are also known as involucral bracts. In the present work bracts of 20 tribes of the family Asteraceae have been presented. On the basis of present 1445 studied genera, The classification of Compositae can be updated on the basis of taxonomic studies of variation of bracts.This type of systematic study is a valuable tool for plant taxonomists. This book is neither a conventional text book nor for only examination purposes. It is a little effort to develop interest to...
