This book
There is no complete description of the total anatomy of a palm and yet we claim to present information about all 183 genera which are included in the palm family (Arecaceae). This paradox arises because palms are large organisms of considerable structural complexity that changes with age so that a full description of anatomical variation within a single individual has never been attempted. Nevertheless, our seemingly reductionist approach, which deals with small samples from relatively standard regions, must serve to generate the overview we present in this book. So immediately we make apologies for the evident deficiencies of our work. Furthermore, we deal only with vegetative anatomy: inflorescence, flower, fruit, and seed represent different topics.
The palms are such a distinctive group of plants that it is appropriate to describe their unique anatomical features in detail. They are unusual monocotyledons because they have developed the tree habit in the absence of secondary growth, a feature shared by a few other groups of monocotyledons (e.g. Pandanaceae, bamboos). Because palms cannot increase stem thickness by secondary growth they are developmentally constrained in terms of habit (aerial stems normally unbranched and with a terminal cluster of large leaves), giving them their distinctive physiognomy. They are, with few exceptions, entirely tropical in their distribution and they have become tropical icons, most familiar in the economically important coconut palm.
