Hundreds of nuclear and plastid loci yield novel insights into orchid relationships
American Journal of Botany, Volume 108, Issue 7, Page 1166-1180, July 2021., 2021 PREMISE The inference of evolutionary relationships in the species‐rich family Orchidaceae has hitherto relied heavily on plastid DNA sequences and limited taxon sampling. Previous studies have provided a robust plastid phylogenetic framework, which was used to classify orchids and investigate the drivers of orchid diversification.

Endocarpic trichomes in Vandeae (Orchidaceae) [PDF]
, 2022 Endocarpic trichomes have been analyzed in fruits of 267 species from 80 genera of the orchid tribe Vandeae, using light and scanning electron microscopy. They have been observed for the first time in 56 genera and confirmed in the rest.

Phytotaxa, 2015 Macradenia grandiflora a new species from southeastern Brazil is described and illustrated. It is related to M. lutescens, but differs by the number of lip calli, the size of sepals, petals and lip, the number of flowers per inflorescence, the cuspidate apex of sepals and petals, and the irregularly lacerate margin of the clinandrium.

Phytotaxa, 2016 The subtribal delimitation and relationship of Old World Cymbidiinae and Eulophiinae within Cymbidieae remain unresolved. Relationships among all subtribes of Cymbidieae (Orchidaceae: Epidendroideae) were estimated using the coding genes psaB, rbcL, matK, ycf1 and Xdh for 103 taxa. The results indicate that most of the clades are successively sister to

Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, 2019 Las orquídeas Epidendroideae presentan el polen organizado en polinios con diferente grado de compactación; cada polinio puede contener hasta 4 millones de granos de polen. En este estudio se evaluó la viabilidad y la germinación in vitro del polen aglutinado en polinios.

Convergent evolution of floral signals underlies the success of Neotropical orchids [PDF]
, 2013 The great majority of plant species in the tropics require animals to achieve pollination, but the exact role of floral signals in attraction of animal pollinators is often debated.

A new overlooked species and a new record of Cyrtopodium (Cymbidieae, Orchidaceae) from Uruguay
Phytotaxa, 2023 Cyrtopodium izaguirreae, a new species from Uruguay is described and compared with morphologically similar taxa. The species was previously mistaken with C. brandonianum, but differs by smaller flowers, proportionally shorter and broader leaves, and geographic distribution restricted to Uruguay. The pinkish lip resembles C. brandonianum and C. pallidum,

Ontogeny of the extrafloral nectaries of Vigna adenantha (Leguminosae, Phaseolae) and its relation with floral development [PDF]
, 2014 Background: The inflorescences of the genus Vigna Savi have extrafloral nectaries (EFNs) among the flowers whose origin is still unknown. The disposition, anatomy and morphology, as well as the ontogeny of the extrafloral nectaries (EFNs) associated with
