A facsimile of the Orchidaceae, Flora of Panama, which originally appeared in four separate issues of the Annals of the Missouri Botanical Garden from 1946 to 1949. Contains an updated checklist, about 800 species, by R. L. Dressler.
The 29 genera of this subtribe, which contains about 4,000 species, are discussed and illustrated. The introduction contains a detailed discussion of pleurothallid morphology and a key to the genera.
Each of the 100 species of Trichosalpinx found in the New World tropics are described and illustrated in this volume. Addenda contain species new and old of previously treated genera.
The latest volume in this series treats three distinct subgenera of the immense genus Pleurothallis, which includes about 30 subgenera and over 3,000 species. Subgenus Crocodeilanthe contains 70 comparatively large species, whereas subgenus Rhynchopera has eight species and subgenus Talpinaria only four species.
This volume treats six infrageneric subdivisions of the genus Pleurothallis: section Abortivae, section Truncatae, two subsections (Acroniae and Pleurothallis) of section Pleurothallis, and two subgenera: Dracontia and Unciferia. Twenty-one new species are described in the Addenda. 111 species are illustrated in black and white.
Icones 18 contains section Pleurothallis subsections Antenniferae, Longiracemosae, and Macrophyllae, and subgenera Pseudostelis and Acuminatia on 182 pages with 172 line drawings, and with the addenda occupying about one-fourth the volume of the book. The species treated are characterized by a usually many-flowered, racemose inflorescence, which is reduced to a single flower in a few species. Many of the species are frequently cultivated.
A guide to Pleurothallis with keys to subgenera, sections, and subsections, and lists of representative species for each infrageneric taxon.
The 33 taxa included in these pleurothallid genera are not closely related, but each has a similar pollination mechanism.
Eight species of Dresslerella and 44 species of Scaphosepalum.
Species in these subgenera are described, keyed, and illustrated.
The newest orchid title from the Press is Updated Checklist of the Orchids of Vietnam, by Leonid Averyanov and Anna Averyanova. This book is 101 pages long and covers 897 species in 152 genera now known for Vietnam, representing approximately 75-80% of the orchids probably occurring in that country. Written in English and Vietnamese with maps, tables, and line drawings throughout, this book is sure to provide further impetus for exploration of this floristically rich nation.
MSB 79 Icones Pleurothallidinarum XX: Systematics of Jostia, Andinia, Barbrodria, Pleurothallis and Subgenera Antilla, Effusia and Restrepiodia with addenda to Lepanthes, Masdevallia and Pleurothallis.
Myoxanthus is described, and a key to the subgenera and species is given. Each species is described and illustrated with a black-and-white line drawing, and distribution maps are given. Types and representative specimens are listed, followed by a brief discussion.
Distribution maps and 100 full-page B&W line art that feature detailed floral dissections appear in each of six fascicles in this series. The plates are punched and bound in a plastic binder for ease of use.
Masdevallia Part Three continues with subsections Masdevallia and Minutae, together containing about another 100 species, each with at least one black-and-white illustration in addition to the text, citation of collections, and distribution maps. A looseleaf version is also available.
