The Odontoglossum Story

A new monograph by Stig Dalström, Wesley E. Higgins and Guido Deburghgraeve

The most comprehensive treatment of Odontoglossum since James Bateman’s classic Monograph of Odontoglossum in 1874.

The Odontoglossum Story is a monographic treatment with a new classification of the genus, which is divided into 6 sections, and further subdivided into series of similar species. This revised classification is based on the latest DNA science combined with morphological characteristics. The book presents all 77 species currently recognized in the genus. Nine natural Odontoglossum hybrids are also included as samples of the prolific tendency of many species to cross-pollinate with other sympatric members of the genus.

Each species is fully described and illustrated with a line drawing as well as with brilliant photographs. Many are taken in the natural habitat. Each species distribution is visually demonstrated with a map and by citations of examined herbarium specimens. Additionally, the story behind each species is presented in layman’s terms which make this monograph enjoyable reading.

Problems with generic delimitation in the Odontoglossum complex (Orchidaceae, Oncidiinae) and an attempt for a solution | SpringerLink

A scientific paper examining the relationships between Odontoglossum and related genera and methods for establishing these relationships. This paper is available for download as a PDF from Springer. The Abstract is below.

Abstract
Concepts of the generic delimitation in the Odontoglossum complex are revised. Comparative morphology of previously recognized genera: Cochlioda, Collare–stuartense, Odontoglossum, Solenidiopsis, and Symphyglossum is presented. Differences between those taxa are compared with the results of molecular studies. A new combination within Collare–stuartense is proposed.

A Comprartive Analysis of Four Populations of Odontoglossum crispum Lindl in Columbia

A scientific paper examining the relationships between Odontoglossum and Oncidium. The paper first discusses the latest scholarship rejecting the Chase et al (2008) classification of Odontoglossum crispum to Oncidium axleandrae and why. The paper further reviews populations Odontoglossum crispum and reviews the comparison between those populations. This paper is available for download as a PDF from ResearchGate. The Abstract is below.

Abstract
A comparative analysis of four populations of Odontoglossum crispum Lindl. are made. Four plants representing the range of variation found at each locality were chosen for study: Velez, Santander; Cabrera, Fusagasuga, Cundinamarca; Villa Gomez, Pacho, Cundinamarca; San Francisco, Putumayo.
