Native Orchids of Trinidad and Tobago provides detailed descriptions of the native species and varieties of orchids from Trinidad and Tobago. The Orchidaceae is the largest family of flowering plants with between 15,000 and 20,000 known species and varieties in from 500 to 600 genera; and new ones are being discovered by almost every botanical expedition to tropical areas. In Trinidad and Tobago, the Orchidaceae is the second largest family of flowering plants in terms of number of species. The native species and varieties known at the present time number 181, and they belong to sixty-six genera. The genera are enumerated in strict phylogenetic sequence, in accord with SCHLECHTER'S system. The species are listed alphabetically under the genera. An attempt has been made throughout to indicate synonymy as completely as possible even to the inclusion of binomials, which have never been used in connection with the flora of Trinidad and Tobago. The description of each genus has for the most part been drawn up to cover the morphological limits shown by the concept throughout its entire geographic range, whereas the specific descriptions are usually based only upon material collected in Trinidad and Tobago.

This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
