Elaiophores in Gomesa bifolia (Sims) M.W. Chase & N.H. Williams (Oncidiinae: Cymbidieae: Orchidaceae): structure and oil secretion [PDF]
Annals of Botany, 2009 Oils are an unusual floral reward in Orchidaceae, being produced by specialized glands called elaiophores. Such glands have been described in subtribe Oncidiinae for a few species. The aims of the present study were to identify the presence of elaiophores in Gomesa bifolia, to study their structure and to understand how the oil is secreted ...

Charles Darwin on Catasetinae (Cymbidieae, Orchidaceae)
Harvard Papers in Botany, 2018 The background and accomplishments of Darwin's work on Catasetinae are analyzed, and issues that he and others did not resolve are discussed in detail. The segments on Catasetinae published by Darwin in the Annals and Magazine of Natural History in September 1869 and in the second edition of his orchid pollination opus (as Catasetidae) published in ...

Interaction between Cymbidium aloifolium and Apis cerana: Incidence of an outlier in modular pollination network of oil flowers [PDF]
Ecology and Evolution, Volume 12, Issue 3, March 2022., 2022 Cymbidium aloifolium is a perennial, epiphytic orchid found in the tropical regions of South Asia. Its oil‐rewarding flowers are invariably pollinated by a non‐oil bee, Apis cerana indica. The study highlights the mechanism and traits that establish floral constancy and pollination mutualism. Photo: Arjun Adit Abstract So far, oil‐rewarding flowers are

Symbiont switching and trophic mode shifts in Orchidaceae [PDF]
New Phytologist, Volume 231, Issue 2, Page 791-800, July 2021., 2021 Summary Mycorrhizal fungi are central to the biology of land plants. However, to what extent mycorrhizal shifts – broad evolutionary transitions in root‐associated fungal symbionts – are related to changes in plant trophic modes remains poorly understood.

Plastid phylogenomics reveals evolutionary relationships in the mycoheterotrophic orchid genus Dipodium and provides insights into plastid gene degeneration [PDF]
Front Plant SciThe orchid genus Dipodium R.Br. (Epidendroideae) comprises leafy autotrophic and leafless mycoheterotrophic species, with the latter confined to sect. Dipodium. This study examined plastome degeneration in Dipodium in a phylogenomic and temporal context.

Two new miniature species of Cymbidium sect. Jensoa (Orchidaceae, Cymbidieae) from southern Vietnam
TurczaninowiaTwo new species of Cymbidium sect. Jensoa (Orchidaceae) are described from southern Vietnam as new for science under the names C. ledinhhienii and C. sungwookii. Both species morphologically are most similar to C. nanulum but clearly differ by the epigeous pseudobulbs and articulate perennial leaves when plant flowers with leaves. Diagnostic characters

Phylogenetics of tribe Collabieae (Orchidaceae, Epidendroideae) based on four chloroplast genes with morphological appraisal. [PDF]
PLoS ONE, 2014 Collabieae (Orchidaceae) is a long neglected tribe with confusing tribal and generic delimitation and little-understood phylogenetic relationships. Using plastid matK, psaB, rbcL, and trnH-psbA DNA sequences and morphological evidence, the phylogenetic ...

Specimen Identification Through Multilocus Species Tree Constructed From Single‐Copy Orthologs (SCOs): A Case Study in Cymbidium Subgenus Jensoa [PDF]
Ecology and Evolution, Volume 15, Issue 4, April 2025.Standard DNA barcodes often fail to distinguish closely related plant species due to deep coalescence, hybridization, and low‐sequence variation. In this study, we demonstrate that single‐copy orthologs (SCOs), widely used in metazoan taxonomy, can serve as effective multilocus markers for plant species identification.

The genome of Cymbidium sinense revealed the evolution of orchid traits [PDF]
Plant Biotechnology Journal, Volume 19, Issue 12, Page 2501-2516, December 2021., 2021 Summary The Orchidaceae is of economic and ecological importance and constitutes ˜10% of all seed plant species. Here, we report a genome physical map for Cymbidium sinense, a well‐known species belonging to genus Cymbidium that has thousands of natural variation varieties of flower organs, flower and leaf colours and also referred as the King of ...
